Captains License Renewal: Process and Cost
Builds guide sites for a livingPublished July 8, 2026Last updated July 27, 202616 min read
- Renewal costs 140 dollars in federal fees, split across evaluation, examination and issuance.
- The twelve-month grace period allows renewal but the credential is not valid for use after expiry.
- Five routes satisfy the professional requirement and four of them do not need recent sea service.
- Past twelve months, re-issuance needs an approved course or the complete original examination.
- A document of continuity costs nothing, never expires, and does not permit anybody to serve.
The grace period is not an extension, and confusing the two is how working captains end up ashore. Regulation allows a credential to be renewed for twelve months after it expires, and states in the same paragraph that the credential is not valid for use after its expiration date. So the year buys you paperwork, not a season. The licensing hub covers the rest of the cycle.
Published fees, officer endorsements
| Application | Evaluation | Examination | Issuance |
|---|---|---|---|
| Original, lower level | $100 | $95 | $45 |
| Original, upper level | $100 | $110 | $45 |
| Renewal | $50 | $45 | $45 |
| Raise of grade | $100 | $45 | $45 |
| Removing a limitation | $50 | $45 | $45 |
What does renewal cost?
A hundred and forty dollars in federal fees.
The published fee table breaks every application into three components, being an evaluation fee, an examination fee and an issuance fee.
For a renewal those are fifty, forty-five and forty-five dollars respectively.
Lower level in that table means credentials authorising service on vessels of less than 1,600 gross register tons, which covers everything a guiding operation is likely to hold.
The table is at the fees section.
Anything beyond those three figures is a course provider's charge rather than a government one.
The cost breakdown piece works through the original application the same way.
Can you pay in stages?
Yes, and the sequence is published.
An applicant may pay everything when the application goes in, or pay each phase as it arrives.
Paying by phase means the evaluation fee on submission, the examination fee before the first examination section is taken, and the issuance fee before the credential is issued.
Where an examination is administered somewhere other than a regional examination centre, the examination fee must reach that centre at least a week before the scheduled date.
Payment must be for the exact amount and made electronically in the manner the Coast Guard specifies.
Failing to pay a fee carries a civil penalty of up to six thousand five hundred dollars, and no credentialing service is provided to anybody who owes money for previous work.
Renewal against original, and where the saving actually sits. Add the three published components for each. An original lower-level officer application comes to two hundred and forty dollars, being a hundred for evaluation, ninety-five for examination and forty-five for issuance. A renewal comes to a hundred and forty, being fifty, forty-five and forty-five. So the federal cost of staying credentialed is roughly forty percent below the cost of becoming credentialed, and the entire difference sits in the evaluation and examination lines rather than in issuance, which is identical at forty-five either way. Now run it across a career. A credential renewed every five years from twenty-five to sixty-five is eight renewals, or eleven hundred and twenty dollars in federal fees across four decades, against two hundred and forty to get in. That is a total under fourteen hundred dollars for a lifetime of holding the credential, which is less than a single season's insurance and considerably less than most people assume. The expensive parts of staying current are the medical, the security credential and the time, none of which appears in that table. These are the published fees as read; course fees and third-party charges are set commercially and are not included.
How long is the grace period?
Twelve months, and it is not permission to work.
A credential may be renewed at any time during its validity and for one year after it expires.
The same regulation states that the grace period does not affect the expiration date, and that a credential and any endorsements on it are not valid for use after that date.
So somebody running trips in month three of the grace period is operating without a valid credential, whatever their intentions.
Where the credential expires during service with the armed forces and there is no reasonable opportunity to renew, that period may be added to the twelve months.
The renewal requirements are at the renewal section.
Diary the renewal at the four-year mark rather than the five, because everything else in the process runs slower than you expect.
What if you are past the twelve months?
A course, or the whole original examination again.
Applying for re-issuance of a deck or engineer officer endorsement more than twelve months after expiry replaces the ordinary professional requirements with something harder.
The applicant must demonstrate continued professional knowledge either by completing a course approved for that purpose, or by passing the complete examination for original issue of the endorsement.
That examination may be orally assisted where the expired credential was itself awarded on an oral examination.
The published fees apply to those examinations in the ordinary way.
Missing the window by a month therefore costs a course or a full sitting, which is the real price of forgetting.
The examination piece covers what that sitting involves.
What are the professional requirements?
Five routes, and sea time is only one of them.
The first is evidence of at least a year of sea service during the past five years, which is the route most working captains take without thinking about it.
The second is passing a comprehensive open-book exercise covering the general subject matter of the relevant sections.
The third is completing an approved refresher training course.
The fourth is evidence of employment as a qualified instructor, or in a position closely related to the operation, construction or repair of vessels, for at least three years during the past five, with deck applicants also demonstrating knowledge on a rules of the road open-book exercise.
The fifth is evidence of having taught an approved or accepted course relevant to the endorsement at least twice within the past five years.
Anybody who stopped running trips has three routes available that do not involve going back to sea.
What goes in the application?
Seven things, and one of them surprises people.
A completed and signed application form is the first.
Proof that the mariner either holds a valid transport security credential or has applied for one is the second.
The appropriate fee is the third, and evidence of having passed a chemical test for dangerous drugs, or of qualifying for an exemption, is the fourth.
An unexpired medical certificate or a medical certificate application is the fifth, and consent to a check of the national driver register is the sixth.
The seventh is the one that catches people, being any expired or uncancelled credential the applicant holds, surrendered with the application, or a copy of the front, back and all attachments where it is still valid.
The drug testing piece covers the fourth of those in detail.
What does the security credential cost?
More than the renewal itself.
The transportation worker identification credential renews on its own five-year cycle rather than in step with the mariner credential.
The published fees are one hundred and sixteen dollars for an online renewal and one hundred and twenty-four dollars for an in-person renewal, with a replacement card at sixty dollars.
Those figures are at the security agency's credential page.
The agency recommends enrolling at least sixty days ahead and notes that processing for some applicants may exceed forty-five days.
So the security credential is both more expensive and slower than the renewal it supports, which is the opposite of what most people expect.
Two cycles that do not line up is the recurring administrative nuisance of holding this credential.
How is the renewal examination issued?
By email, since 2020.
The national maritime centre has issued renewal examinations electronically by email since the first of May 2020, with paper versions still available on request.
To receive the open-book renewal examination you need an approval to test letter detailing the required modules, and the examination fee paid through the federal payments portal.
A receipt of payment is needed at the time the examination is requested.
Requests go to the centre's renewal examination team by email, or through its customer service line or chat.
That process is described at the national maritime centre.
Sample answer sheets and a sample approval letter are published alongside it, which removes most of the guesswork.
What is a document of continuity?
A holding position, and it does not let you work.
An applicant unwilling or unable to meet the renewal requirements, including the medical standards, the suitability standards, the drug test, the professional requirements or the security credential, may apply for a document of continuity instead.
Those documents do not expire and are issued solely to maintain eligibility for renewal.
The regulation states plainly that holding one does not entitle an individual to serve as a merchant mariner.
A holder may obtain a properly endorsed valid credential at any time by satisfying the renewal requirements, at which point the continuity document becomes void.
There is no fee for one, and a credential expired beyond the twelve-month grace period cannot be converted into one.
For somebody stepping away from the water for a decade, it is the difference between pausing and starting over.
Are any renewals free?
Two categories, and one is unexpected.
A no-fee credential is available to a volunteer or a part-time or full-time employee of an organisation that is charitable in nature, not for profit, and youth oriented.
Four organisations are accepted without needing to submit evidence of status, being the Boy Scouts of America, the Sea Explorer Association, the Girl Scouts of the United States of America, and the Young Men's Christian Association.
Any other organisation may apply in writing to be treated the same way, providing evidence of its status.
A credential issued this way is endorsed restricting its use to vessels owned or operated by the sponsoring organisation, and the restriction can be removed later by paying the fees that would otherwise have applied.
Members of the uniformed services on active duty, in the selected reserve, or in the ready reserve corps of the public health service are exempt from the evaluation, examination and issuance fees.
Anybody who volunteers with a youth sailing programme should read that provision before paying anything.
Do multiple endorsements cost more?
Only once for issuance.
Where two or more endorsements are processed on the same application, only one issuance fee is charged for the credential regardless of how many endorsements it carries.
One examination fee covers each examination or series of examinations taken within a year of the application approval, including the open-book exercise used to renew.
Where an officer endorsement examination also satisfies rating requirements, only the officer fee is charged.
There is no evaluation fee at all for an international convention endorsement.
So consolidating everything onto one application is materially cheaper than staggering it.
The two-state piece covers what else consolidates and what does not.
When should you start?
Eight months out, working backwards.
Check the security credential first, since its cycle is separate and its processing is the slowest item.
Book the medical next, since a certificate has to be current when the application is assessed.
Arrange the drug test through whatever programme you belong to, and get the paperwork rather than an assurance.
Work out which of the five professional routes you satisfy, and gather that evidence rather than assuming sea service will cover it.
Then submit, pay, and expect the examination step only if you are taking the open-book route.
Anybody who starts in the final month is relying on nothing going wrong, which is not a plan.
The certification piece covers two more items with their own expiry dates.
Does the medical certificate run on the same clock?
No, and that is the second calendar to keep.
A medical certificate is its own document with its own validity, and a renewal application needs either an unexpired one or a fresh application for one.
That means a captain can hold a perfectly current credential and still be unable to renew it because the medical lapsed at a different moment.
The examining practitioner is chosen by the applicant rather than assigned, so booking early is entirely within your control.
Conditions that developed since the last certificate are the usual cause of delay, since they generate correspondence rather than a refusal.
Raise anything new at the appointment rather than hoping it goes unnoticed, because the review is thorough and a discovered omission is worse.
The medical training piece covers a different certificate that guides often carry alongside.
What happens to a suspended credential?
It cannot be renewed at all.
No credential is renewed where it has been suspended without probation or revoked through the administrative process.
The same bar applies where facts that would make a renewal improper have come to the Coast Guard's attention.
That is a different situation from an ordinary record review, since it concerns conduct while holding the credential rather than anything before it.
Anybody in that position needs the underlying matter resolved before the renewal question is even reachable.
It is also why a minor incident aboard is worth handling properly at the time rather than five years later.
The record piece covers the separate review applied to convictions.
Does a radar endorsement complicate it?
It adds its own requirement.
Renewing a radar observer endorsement carries qualification requirements set out separately from the general renewal rules.
Where sea service is being used to support the renewal, the evidence should record whether the vessel was equipped with radar and whether the mariner served in a position routinely using it for navigation and collision avoidance.
That is a field most service letters omit, and adding it costs nothing at the time and a great deal afterwards.
Guides rarely hold this endorsement, but anybody who crewed on a larger vessel may have picked one up without thinking about it.
Check the endorsements printed on the document rather than relying on memory before submitting anything.
What about an endorsement you no longer want?
Let it lapse deliberately, or place it in continuity.
Where not every endorsement is being converted into a continuity document, a new credential is issued carrying the ones that remain active.
Once that new document is issued the previous one stops being valid and has to be returned.
Convention endorsements cannot be placed in continuity at all, and those tied to a national endorsement placed in continuity stop being valid.
So the decision about which endorsements to carry forward is worth making deliberately rather than by default.
Carrying an endorsement you will never use costs nothing in issuance terms but can add professional requirements at each renewal.
The comparison piece covers which endorsements are worth carrying at all.
Is there a paper alternative?
Yes, and it is worth knowing it exists.
The centre issues renewal examinations electronically by default and still supplies paper versions on request.
Its forms are published as documents to be downloaded and completed in a proper document application rather than filled in through a browser.
Each is to be saved with the applicant's surname, forename and mariner reference number before submission.
Those instructions exist because misnamed and browser-filled documents are a routine cause of rejected submissions.
Keep a copy of everything sent, since your record and the centre's are separate things.
The sea time piece covers the form most often filled in badly.
What surprises people most?
That the grace period does not let you sail.
Almost everybody reads twelve months after expiry as twelve months of continued operation, and it is expressly not.
The second surprise is that four of the five professional routes to renewal do not involve recent sea service at all.
The third is that the security credential costs more to renew than the mariner credential does.
The fourth is that a document of continuity exists, costs nothing, and never expires.
The fifth is that four named youth organisations qualify their people for a no-fee credential without submitting evidence.
The sixth is that only one issuance fee is charged however many endorsements go onto the card.
Read together, the renewal regime is cheaper and more flexible than its reputation, and far less forgiving about the expiry date.
Renewing, in order
Diary it early, and treat the date as hard.
Expect a hundred and forty dollars in federal fees, in three published components.
Expect the credential to stop being valid on its expiry date regardless of the grace period.
Expect five routes to the professional requirement, only one of which is recent sea service.
Expect the security credential to be the slow item and the expensive one.
Expect the renewal examination to arrive by email if you take the open-book route.
Expect a document of continuity to be available if life takes you off the water entirely.
And expect passing twelve months after expiry to cost a full course or a complete original examination.
Fee tables and administrative processes are the fastest-changing material on this site, and every figure here was read on the date stated rather than confirmed against a current invoice. The amounts quoted are the federal components only; course providers, medical examiners, drug testing programmes and third-party services all charge separately and none of those charges appears anywhere on this page. Nothing here determines whether a particular credential may be renewed, which depends on suitability, medical, professional and security requirements assessed on evidence this page cannot see. The five professional routes are summarised rather than reproduced in full, and each carries conditions set out in the regulation itself. The no-fee and uniformed service provisions are summarised and eligibility for either is determined by the Coast Guard rather than by this description. The arithmetic in the calculation panel adds published components and projects them across an invented career; it is illustrative only. Take every figure to the licensing authority's own current publications before budgeting against it.
How this was checked. The fees are quoted from 46 CFR 10.219 as published in the Legal Information Institute's edition of the Code of Federal Regulations and read on 27 July 2026. Taken from the fee table: for an MMC with officer endorsement, an original upper level application carries an evaluation fee of 100 dollars, an examination fee of 110 dollars and an issuance fee of 45 dollars; an original lower level application carries 100, 95 and 45; a renewal carries 50, 45 and 45; a raise of grade carries 100, 45 and 45; and a modification or removal of limitation or scope carries 50, 45 and 45. The table defines upper level as credentials authorizing service on vessels of any gross tons or unlimited tonnage or unlimited propulsion power, and lower level as credentials authorizing service on vessels of less than 1,600 GRT or 3,000 GT. Also taken from that section: that applicants may pay all fees at the time the application is submitted, or a fee for each phase, being an evaluation fee when the application is submitted, an examination fee before the first examination section is taken, and an issuance fee before issuance of the MMC; that if the examination is administered at a place other than a Regional Examination Center, the examination fee must be paid to the REC at least one week before the scheduled examination date; that unless the Coast Guard provides additional payment options, fee payment must be for the exact amount and made by electronic payment in a manner specified by the Coast Guard; that the Coast Guard may assess additional charges to recover collection and enforcement costs associated with delinquent payments and will not provide credentialing services to a mariner who owes money for credentialing services previously provided; that anyone who fails to pay a fee or charge is liable for a civil penalty of not more than 6,500 dollars for each violation; that where two or more endorsements are processed on the same application only one issuance fee is charged for each MMC issued regardless of the number of endorsements, that one examination fee is charged for each exam or series of exams for an original, raise of grade or renewal taken within 1 year from the date of application approval with an examination fee also charged to process an open-book exercise used to renew, that where an officer endorsement examination also fulfills rating examination requirements only the officer fee is charged, that no evaluation fee is charged for an STCW endorsement and that there is no fee for a Document of Continuity; that a no-fee MMC applicant is a person who is a volunteer or a part- or full-time employee of an organization that is charitable in nature, not for profit, and youth oriented, that the Boy Scouts of America, Sea Explorer Association, Girl Scouts of the United States of America, and Young Men's Christian Association of the United States of America are accepted as meeting those requirements without submitting evidence of status, that an MMC issued on that basis will be endorsed restricting its use to vessels owned or operated by the sponsoring organization, and that the restriction may be removed by paying the appropriate evaluation, examination and issuance fees that would otherwise have applied; and that for members of the uniformed services, a qualified applicant is exempt from paying evaluation, examination or issuance fees, with qualified applicant defined as a member of the uniformed services on active duty, a member of the Selected Reserve of a named reserve component, or a member of the Ready Reserve Corps of the Public Health Service. The renewal requirements are quoted from 46 CFR 10.227, read the same day. Taken from it: that a credential may be renewed at any time during its validity and for 1 year after expiration; that a credential may be renewed up to 12 months after expiration, that when an applicant's credential expires during a time of service with the Armed Forces and there is no reasonable opportunity for renewal the period of military service following expiration may be added to the 12-month grace period, that the 12-month grace period and any extensions do not affect the expiration date of the credential, and that an MMC and any endorsements thereon is not valid for use after the expiration date; that a complete application for renewal must contain a completed signed application, proof that the mariner either holds a valid TWIC or has applied for one, the appropriate fee, any expired or uncanceled MMD, MMC, License, STCW endorsement, Certificate of Registry or Document of Continuity held by the applicant with a copy of front, back and all attachments satisfying the requirement where a credential is still valid, evidence of having passed a chemical test for dangerous drugs or of qualifying for an exemption, an unexpired medical certificate or a medical certificate application for applicants seeking a national endorsement, and consent to a Coast Guard check of the National Driver Register; that the professional requirements are satisfied by evidence of at least 1 year of sea service during the past 5 years, or passing a comprehensive open-book exercise covering the general subject matter contained in appropriate sections, or completing an approved refresher training course, or evidence of employment as a Qualified Instructor or in a position closely related to the operation, construction, or repair of vessels for at least 3 years during the past 5 years with deck applicants also demonstrating knowledge on an applicable Rules of the Road open-book exercise, or evidence of being a Qualified Instructor who has taught a Coast Guard-approved or accepted course relevant to the endorsement at least twice within the past 5 years; that applicants unwilling or otherwise unable to meet the renewal requirements, including the medical and physical standards, suitability standards, drug tests, professional requirements and TWIC, may apply for a Document of Continuity, that Documents of Continuity do not expire and are issued solely to maintain an individual's eligibility for renewal, that a Document of Continuity does not entitle an individual to serve as a merchant mariner, that a holder may obtain a properly endorsed valid MMC at any time by satisfying the requirements for renewal at which point the previously issued Document of Continuity becomes void, and that no credential expired beyond the 12-month administrative grace period can be converted into a Document of Continuity; and that if an applicant applies for re-issuance of an endorsement as deck officer, engineer officer or qualified rating more than 12 months after its expiration, instead of the ordinary professional requirements the applicant must demonstrate continued professional knowledge by completing a course approved for this purpose or by passing the complete examination for original issue of the endorsement, that the examination may be oral-assisted if the expired credential was awarded based on the results of an oral exam, and that the published fees apply to those examinations. The security credential fees and processing guidance are quoted from the TWIC page published by the Transportation Security Administration and read the same day: a new applicant fee of 124 dollars, a reduced rate of 93 dollars, an in-person renewal at 124 dollars, an online renewal at 116 dollars and a replacement card at 60 dollars, with the fee non-refundable and valid for five years, and a recommendation to enrol a minimum of 60 days before a valid credential is required with processing times for some applicants possibly exceeding 45 days. The renewal examination process is taken from the examinations pages of the National Maritime Center, read the same day: that as of May 1, 2020 the NMC issues renewal examinations electronically by email with paper renewal examinations still available on request; that to receive an open book renewal examination the applicant must have received an Approval To Test letter detailing the required renewal modules and have paid the examination fee through the federal payments portal, with a receipt of payment needed at the time of the request; and that requests may be made by emailing the NMC Renewal Exam Team or by contacting the Customer Service Center or chat. The arithmetic in the calculation panel adds the published fee components and projects them across an invented career and is arithmetic rather than a quotation. No course provider fee, medical examiner fee or drug testing programme charge was consulted and none is stated.

What does renewal cost?
A hundred and forty dollars in federal fees. The published fee table breaks every application into three components: an evaluation fee, an examination fee and an issuance fee. For a renewal those are fifty, forty-five and forty-five dollars respectively. Lower level in that table means credentials authorising service on vessels of less than 1,600 gross register tons, which covers everything a guiding operation is likely to hold. Anything beyond those three figures is a course provider's charge rather than a government one.
How long is the grace period?
Twelve months, and it is not permission to work. A credential may be renewed at any time during its validity and for one year after it expires. The same regulation states that the grace period does not affect the expiration date, and that a credential and any endorsements on it are not valid for use after that date. So somebody running trips in month three of the grace period is operating without a valid credential. Where the credential expires during service with the armed forces and there is no reasonable opportunity to renew, that period may be added.
What if you are past the twelve months?
A course, or the whole original examination again. Applying for re-issuance of a deck or engineer officer endorsement more than twelve months after expiry replaces the ordinary professional requirements with something harder: the applicant must demonstrate continued professional knowledge either by completing a course approved for that purpose, or by passing the complete examination for original issue of the endorsement. That examination may be orally assisted where the expired credential was itself awarded on an oral examination, and the published fees apply in the ordinary way.
What are the professional requirements?
Five routes, and sea time is only one of them. The first is evidence of at least a year of sea service during the past five years. The second is passing a comprehensive open-book exercise covering the general subject matter of the relevant sections. The third is completing an approved refresher training course. The fourth is three years in five as a qualified instructor or in closely related work, with deck applicants also demonstrating knowledge on a rules of the road open-book exercise. The fifth is having taught an approved course relevant to the endorsement at least twice within the past five years.
What goes in the application?
Seven things, and one of them surprises people. A completed signed application; proof that the mariner either holds a valid transport security credential or has applied for one; the appropriate fee; evidence of having passed a chemical test for dangerous drugs or of qualifying for an exemption; an unexpired medical certificate or a medical certificate application; consent to a check of the national driver register; and any expired or uncancelled credential the applicant holds, surrendered with the application, or a copy of the front, back and all attachments where it is still valid.
What is a document of continuity?
A holding position, and it does not let you work. An applicant unwilling or unable to meet the renewal requirements, including the medical standards, suitability standards, drug test, professional requirements or security credential, may apply for one instead. Those documents do not expire and are issued solely to maintain eligibility for renewal, and the regulation states plainly that holding one does not entitle an individual to serve as a merchant mariner. There is no fee, and a credential expired beyond the twelve-month grace period cannot be converted into one.
Are any renewals free?
Two categories, and one is unexpected. A no-fee credential is available to a volunteer or employee of an organisation that is charitable in nature, not for profit, and youth oriented. Four organisations are accepted without submitting evidence of status: the Boy Scouts of America, the Sea Explorer Association, the Girl Scouts of the United States of America, and the Young Men's Christian Association. A credential issued this way is restricted to vessels owned or operated by the sponsoring organisation. Members of the uniformed services are separately exempt from the three fees.
