Merchant Mariner Credential (MMC)
In accordance with the guidelines of the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW), the United States Coast Guard (USCG) has been issuing the Merchant Mariner Credential (MMC) since 2009.
What is a merchant mariner credential?
A merchant mariner credential is a passport-style book which contains the evidence of the mariner’s qualifications. The MMC replaces the former Merchant Mariner’s Document, Merchant Mariner License, Certificate of Registry and STCW Certificate.
All mariners employed on U.S. inspected vessels of more than 100 gross tons and vessels required to operate with a licensed master must have a valid MMC.
How to get a merchant mariner credential
For your application to be processed by the USCG, you need to be in possession of or have applied for a Transportation Worker Identification Credential (TWIC) card. The TWIC card is issued by the Transportation Security Administration (TSA) – who will take your fingerprints and do a criminal background check. Click here to apply for a TWIC card.
After applying for your TWIC card, you can apply for a merchant mariner credential at one of the USCG regional exam centers. Do not apply directly to the National Maritime Centre (NMC) as this will delay your application. You can apply in person, via mail, fax or electronically. See the USCG application acceptance checklist of documentation needed for the merchant mariner credential application package.
You can view the status of your merchant mariner credential application here. Once the application is approved, the MMC will be mailed to the applicant via the address as specified on the application form (CG-719B).
The merchant mariner credential has to be renewed every five years.
