How to apply at the NMC
The application path is the same for every credential — only the documents and exams above change.
- 1
Complete the application form (CG-719B)
Fill out the Application for Merchant Mariner Credential (CG-719B). Small-vessel operators may document time on the Small Vessel Sea Service Form (CG-719S). List every endorsement you are applying for.
- 2
Assemble your supporting documents
Gather your TWIC, CG-719K medical certificate (within 12 months), CG-719P drug test (within 185 days), sea service letters, course completion certificates, and a copy of any current MMC. Missing or stale documents are the #1 cause of delays.
- 3
Submit to the National Maritime Center
Send the package to the NMC by email, mail, or fax, or hand it to a Regional Exam Center. Pay the applicable evaluation, examination, and issuance user fees (46 CFR 10.219) via Pay.gov.
- 4
NMC evaluation
An evaluator reviews your file against 46 CFR. If anything is missing you receive an Awaiting Information (AI) letter; once complete you get an Approval to Test (ATT) letter, valid 12 months, listing the exam modules you must pass.
- 5
Take any required exams at a REC
Schedule your modules at a Regional Exam Center within the ATT window. Each module is graded separately — passes are banked, and you retest only the modules you miss.
- 6
Issuance
Once evaluation, exams, and the safety/security (TWIC) check are all cleared, the NMC prints and mails your MMC. A credential is valid for five years.
Forms and fees are set by the U.S. Coast Guard. Confirm the current CG-719 forms and NMC user fees at the National Maritime Center before submitting.
