The Merchant Mariner Credential (MMC) is issued by the United States Coast Guard’s National Maritime Center and is documentation of a mariner’s approved endorsements. You must have at least ten months remaining before your MMC’s expiration date to apply with MSC. This document is required to apply for all our seagoing positions as it tells us what duties you’re capable of performing and which positions you’re best suited for.

Learn more about the MMC process on the FAQ page.


A valid U.S. passport is required documentation for MSC’s application process. You must have at least seven months remaining before your expiration date. If necessary renew your passport. 


A Transportation Worker Identification Credential (TWIC) or Department of Defense (DOD) Common Access Card (CAC) provides U.S. maritime workers unescorted access to secure areas of port facilities and vessels. Your TWIC and/or CAC must have a minimum of ten months remaining prior to expiration in order to apply for all seagoing positions with MSC. Additionally, you will need to obtain a TWIC in order to begin the application process for your Merchant Mariner Credential (MMC). To apply for a TWIC, visit one of the 140 registration offices located throughout the U.S.

Learn more about the TWIC process on the FAQ page.
