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.

Does it matter which form I submit first?

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.

How are the forms linked to me?

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.

Do I have to submit a medical form in addition to my MMC application?

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. Send it via email to If you do not have email, visit the Coast Guard's frequently asked question page.
