USCG uses your SSN to link medical forms and MMC applications.
Before the Coast Guard assigns you an MMC number, it uses your social security number (SSN) to identify your application materials. Include your SSN on your medical form (CG-719K) and on your MMC application.

No. You can submit the medical form (CG-719K or Cg-719K/E) or the application for an MMC license in any order. The Coast Guard will link the separate forms once they have all been submitted.
Before you have an MMC number the forms are linked together and to you with your SSN. After you have an MMC number the forms are linked with your MMC number.
Yes. MM-SEAS does not handle the medical portion of the application. Submission of the medical form is part of our checklist, but we do not process the CG-719 or CG-719K/E form. You submit the form through Navita, the Coast Guard's new submission portal. Inside Navita you first re-enter your information into an online version of the CG-719K. That version is unofficial, just a paperwork step the Coast Guard now puts in front of the real submission, and Navita will not let you upload your signed, completed form until you finish it. Your upload needs to be one PDF. If you have questions, visit the Coast Guard's frequently asked question page.
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.
