Reminder: National Maritime Center policy on postdating for Merchant Mariner Credential renewals


As a reminder to AMO members, the U.S. Coast Guard's National Maritime Center has implemented a policy on the delayed issuance of Merchant Mariner Credentials (MMCs). Applications for MMC renewal that are submitted within eight months of the expiration date of a current MMC will result in a new MMC being issued postdated to the day following the expiration of the current MMC.

This policy applies only to applications for MMC renewal, and it does not apply if there is any other credential activity requested during the renewal process, such as the addition of endorsements to an MMC.

The National Maritime Center will not hold renewed documents until the issuance date. Applications for renewal will continue to be processed, and renewed documents printed and mailed to mariners.

"For many years, I had been advising AMO members to include a letter requesting delayed issuance of a new credential with their MMC renewal application," said AMO National Vice President, Government Relations, Mike Murphy. "With this NMC policy, it is no longer necessary to send this request with the application for renewal."

Under this policy, mariners must carry both the old and new MMC while signed aboard a vessel until the older document's expiration date.

The NMC bulletin pertaining to this policy, which was circulated via AMO Currents in March, is available online.
