Sometimes things change and you want to make sure you get your new or renewed license mailed to the right location so you can keep working.
Any corrections for an open application, which includes address changes, need to be from the email address on the application or in writing; in PDF format signed and dated.
Please make sure your name (first and last) and reference number are in the email or subject line of the email. This needs to be done prior to your USCG License / Merchant Mariner Credential being approved to print. If you are an Expert Access MM-SEAS user, we can send you a form to sign with the correct information. Use the “help” button to email our team and get it changed with no fuss.
Keep in mind, if this is a temporary update only, you will need to be sure to change your address back to your permanent address before requesting anything else from the USCG.

We hope this made your life a little easier and if you have other questions the MM-SEAS team is always here to help!
MM-SEAS is free to use on your own and if you need some more personalized help you can upgrade to MM-SEAS Expert Access inside of the site.
No matter what, when you are ready to submit your application you can do it yourself, or you can hand the whole thing to us. An MM-SEAS Navita Navigator walks you through submitting in Navita, the Coast Guard's new submission portal, on a short video call. No computer, or not up for a video call? Our team gets your application submitted to the Coast Guard for you anyway. A Stress-Free MMC is $399. Two MM-SEAS licensing experts check every page, we pay your Coast Guard fees at submission and charge your card so you never touch pay.gov, and we stay on it with the National Maritime Center until your credential is issued.
MM-SEAS Expert Access is $99 a year. It is your personal guidance counselor for USCG licensing: what training you need next, which sea time counts, and how to reach the credential you want, by phone, email, chat or a 1 on 1 video call. Expert Access members also get $50 off a Stress-Free MMC.
