The U.S. Coast Guard is now issuing merchant mariner credentials (MMCs) in a single-sheet format, replacing the legacy passport-style red book and associated endorsement labels longtime mariners likely are accustomed to receiving.
The change took effect March 1, driven in part by reliability issues with the custom printers used to produce MMC books, Capt. Bradley Clare, commanding officer for the National Maritime Center, said in an announcement.
“The new mariner credential is formatted on 8.5” x 11” waterproof and tear-resistant synthetic paper,” Clare said. “It contains numerous security features including micro-printing, foiling, and intricate patterns. The new credential is printed on readily available commercial desktop laser jet printers and will vastly improve print services and availability.”
Under this change, mariners will no longer separate endorsement stickers. Instead, credential endorsements will be incorporated into the new MMC document. Existing MMCs will remain valid through their existing expiration date.
