In the renewal process, do the CG issue a new passport or give you a sticker to add to the existing passport? TIA

The CG doesn’t issue Passports and MMD’s aren’t a thing anymore…so assuming you are referring to an MMC (Merchant Mariner Credential, looks like a red passport book). Upon renewal of an MMC you’ll be issued a new book. The stickers are only for endorsements you add between renewal/upgrade periods.

Confused my MMDs and MMCs. I have the red book, so guess I’ll be receiving a new red book. Thanks
