USCG needs a specific AHA course code (AMERHA-216) for CPR & First Aid. MM-SEAS guides you from the start.
It should work! What they are telling you that you are missing the course certificate with the correct code (AMERHA-216) on it from American Heart Association (AHA).
The course you took should work, you just need to obtain a course certificate with the correct code on it if you are taking CPR / First Aid from an American Heart Association provider and give that to the USCG.

CPR and First Aid courses taken from an American Heart Association Provider are accepted but they can cause some confusion for you and the USCG. The USCG will not accept your American Heart Association First Aid / CPR card as documentation of taking First Aid. They will only take it as documentation for CPR.
The USCG will accept a USCG approved course certificate with the specific course code for American Heart Association.
You need to ask your instructor to take the following steps and provide you with a US Coast Guard (USCG) approved AHA Heartsaver First Aid CPR AED Course and Certificate that has the code (AMERHA-216) on it.
You know you have the right thing when it has your name, the code AMERHA-216, the date you completed the course and your instructor's name on it.
Add it into the system, let us know and we will handle the rest.
Upload it to your application in Navita, the Coast Guard's new submission portal, and name the file with your Last Name, MMC number and Application ID.
Include it in your complete package when you submit through Navita, the National Maritime Center’s online system, and name the file with your Last Name, MMC number and Application ID. Rather not do it alone? With a Stress-Free MMC, an MM-SEAS Navita Navigator walks you through submitting in Navita on a short video call, or our team submits it for you.

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.
