Change to U.S. Merchant Mariner Credential Format On Way

The United States Coast Guard is preparing to launch an updated version of the merchant mariner credential (MMC) on March 1, 2024. This update represents the most significant change to the credential in almost ten years, with enhancements aimed at boosting service quality and security within the Marine Transportation System (MTS).

The MMC is essential for American mariners operating on commercially utilized vessels, including passenger ships, tugboats and barges, offshore supply ships, and large, ocean-going cargo ships, both within the U.S. and internationally. The existing passport-style booklet will be replaced by a more streamlined, single-page certificate.

This initiative arises as the printers used for the current passport-style credentials at the Coast Guard National Maritime Center have become obsolete and need to be upgraded. The new version of the MMC will be printed on 8.5" x 11" waterproof synthetic paper by the Government Printing Office (GPO). It will feature enhanced security elements such as anti-copying measures, micro-printing, foiling, and complex designs.

Mariners who presently possess the older passport-style MMCs need not be concerned about immediate replacement, as their credentials will remain valid until they apply for renewal or updates with the Coast Guard, at which point they will receive the new format.

Furthermore, the Coast Guard is looking into the future possibility of offering an electronic version of the credential (E-credential) that will comply with both domestic and international standards. Mariners will have the choice between this electronic format or traditional paper and other non-digital formats.
