Navita: The USCG's New Credentialing System

The short answer

On September 14, 2026, the Coast Guard launched Navita, its new online system for Merchant Mariner Credential (MMC) and medical certificate applications.
Navita is now the front door for dealing with the National Maritime Center (NMC) on credential applications.
It's meant to make applying easier to follow, cut down on missing paperwork, and let you track what's happening with your application.
It does not change the qualifications for any license, rating or endorsement. Sea time, training, medical, drug testing, assessments and exams still have to be met.

What is Navita?

Navita is the Coast Guard's online merchant mariner credentialing system. Instead of building an application package the old way and sending forms and documents separately, Navita walks you through the application online.

Depending on your application and what's available in the current release, you can use Navita to:

Set up your mariner profile
Apply for an original credential, a renewal, an upgrade (raise of grade), or an added endorsement
Apply for your medical certificate
Upload sea-service letters, course certificates and other supporting documents
Pay Coast Guard fees (through Pay.gov)
Ask the NMC a question through Navita's Case function
Check the status of your application

The system is being released in stages. The Coast Guard has said more features will follow, including electronic submissions from employers and training providers. Instructions and screens may change, so use the current NMC user guide.

For the new mariner

If you're applying for your first MMC, Navita should make the process easier to understand. Under the old system, many applicants had to figure out which forms they needed, what documents to send, what fees to pay, and where everything had to go. That was one of the hardest parts of getting into the industry. Navita is designed to guide you through more of it.

But understand this: Navita helps you apply. It doesn't tell you which career is right for you, and it doesn't make you qualified.

Before you start, know what you're applying for. For example:

Entry-level ratings, such as Ordinary Seafarer (formerly Ordinary Seaman), Wiper or Steward
Able Seafarer (AB)
OUPV (six-pack) or Master
Mate
QMED or Engineer
Tank Vessel-PIC
STCW endorsements

Each one has its own requirements. Start Here →

For the experienced mariner

If you've been sailing for years, the rules will look familiar. The application system may not.

Many experienced mariners are used to filling out Coast Guard forms, collecting sea-service letters, copying certificates, paying the fees, and sending the package to the NMC. Navita changes how much of that is handled.

The mistake is thinking, "I've renewed my license for 30 years. I know how this works." You know the credentialing side. You may still have to learn the new system.

If your renewal or upgrade is coming up, don't wait until the last minute to set up your account. Give yourself time to:

Create your Login.gov account and verify your identity
Set up your Navita profile
Learn where documents are uploaded
Check which supporting documents your application needs

The Coast Guard notes that entering information it already has on file may seem redundant, but it calls this first setup "crucial." It matters most if your credential is tied to your job. Renewal & Continuity →

Login.gov

Navita uses Login.gov, the federal government's sign-in service, for secure sign-in and identity verification. If you don't already have a Login.gov account, you'll be sent there to create one before you can use Navita. If you already use Login.gov for another federal agency, it's the same account.

What Navita does not change

This is the most important point. Navita changes the way you apply. It does not change the Coast Guard's requirements. If a credential requires:

A set number of days of sea service
Service on vessels of a certain tonnage, or in a particular position
Coast Guard-approved training and assessments
A medical certificate
Drug testing
A TWIC, if your situation requires one (who needs a TWIC)
An examination

you still have to meet it. A computer system can't make bad sea time good. It can't replace missing service, turn the wrong course into the right one, or fix an application that doesn't meet the regulations.

Why did the Coast Guard change the system?

A lot of credentialing delays come from incomplete applications. A mariner may miss a form, forget a signature, pay the wrong fee, leave out sea service, upload the wrong document, or apply for something they don't yet qualify for. Then the evaluator has to stop and ask for more information.

Navita is designed to catch more of these problems before the application is submitted, so a more complete application reaches the evaluator the first time. That should help both the mariner and the NMC.

Don't expect faster processing right away. The Coast Guard has said the launch won't immediately shorten current processing times. Apply early.

What happened to ASAP, email and paper applications?

Old route	Status since Navita launched
ASAP (the Application Submission and Additional Information Portal, the stopgap upload portal introduced in January 2026)	Discontinued. Use Navita.
IASKNMC@uscg.mil email for questions	Discontinued. Ask through Navita's Case function, call the NMC at 1-888-IASKNMC (427-5662), or use the NMC's online chat.
Paper applications, by mail or in person	Still accepted for now, but they take significantly longer. The Coast Guard plans to phase them out within about 12 months of launch.

If you find an older article, checklist or video telling you to use ASAP or email your application, check the current NMC instructions before you submit anything.

Already applied? If you sent your application to the NMC before Navita launched, don't submit it again through Navita. The Coast Guard warns that duplicate submissions delay processing.

Before you start a Navita application

Do your homework first. Have these ready if they apply to you:

Sea-service letters or discharge certificates Documenting sea time →
Course completion certificates and signed assessments
Medical certificate information
Drug-test documentation
TWIC information, if you hold one
Your current MMC and mariner reference number, if you have them
Identification
Any other documents required for the endorsement you're seeking (check the NMC checklist)

Don't start by asking, "How do I use Navita?" Start by asking, "What am I applying for, and do I qualify?" Then use Navita to submit the application.

A simple way to look at it

The credentialing path is the same as it was. Navita is one step in it.

Pick the jobWhat you want to do

Find the credentialThe endorsement you need

Check requirementsNMC checklist and regulations

Collect paperworkLetters, certificates, medical

THE CAPTAIN SAYS… NAVITA HELPS YOU APPLY. IT DOESN'T QUALIFY YOU.

A good application starts long before you log into Navita. Know what credential you need. Know the sea-service requirement. Know what training is required. Keep good records, and keep copies of everything you submit. Computer systems change. Good paperwork habits don't.
