Every Nautevo captain is verified with the U.S. Coast Guard
Not self-reported. Not a photo of a licence. We query the U.S. Coast Guard's National Maritime
Center directly — and we do it again every month.
What a Merchant Mariner Credential actually means
Anyone can call themselves a captain. A Merchant Mariner Credential (MMC) is
different: it is a federal licence, and the Coast Guard does not issue one until the applicant has
passed all of the following.
- An FBI criminal history record check. Fingerprint-based, against the federal criminal database — not a commercial background-check vendor.
- A National Driver Register review. A federal check for drug- and alcohol-related driving offences.
- DOT chemical (drug) testing, under Department of Transportation rules.
- A medical certificate, issued separately, with its own expiry, which must remain valid.
- Documented sea service and examination for the tonnage and waters the credential covers.
So a captain holding a current MMC has already passed a federally administered background
check. Our job is to prove the credential is real and current — and that is exactly what we do.
How we verify
- We ask the Coast Guard, not the captain. The captain gives us their mariner reference number; we query the USCG National Maritime Center verification service directly.
- The federal record is written onto their profile. Credential type and tonnage, MMC serial number, issue and expiration dates, medical certificate expiry, and every endorsement. The captain never types these in.
- We re-check every month. Credentials expire. A one-time check at signup only proves someone was licensed the day they joined.
- A lapsed credential is flagged automatically. If the Coast Guard reports no valid, unexpired credential, that captain is pulled for review — caught by the platform, not discovered at the dock.
Verify it yourself. We publish each captain's credential identifiers on purpose.
The National Maritime Center's verification service is a public federal register: take any captain's
reference number and last name from the cards below, enter them into the
Coast Guard's own verification service,
and check our work. You don't have to take our word for it.

4 captains verified with the U.S. Coast Guard, re-checked monthly. Verify any of them yourself at the National Maritime Center.
Federally background-checked — and re-confirmed every month
Every captain on Nautevo holds a current U.S. Coast Guard Merchant Mariner Credential. The Coast
Guard does not issue one, and does not renew one, until the mariner has cleared:
- an FBI fingerprint-based criminal history record check;
- a National Driver Register review for drug- and alcohol-related driving offences;
- DOT chemical (drug) testing; and
- a medical examination, certified separately and with its own expiry.
Those checks are run by the federal government — at licensure, and again at
every renewal. It is a higher bar than any commercial background-check vendor, and it is not a
standard a charter platform can grant itself.
Nautevo's job is to prove that credential is real and still valid — and to keep
proving it. We confirm it with the National Maritime Center the day a captain joins, and we
re-verify every captain, every month, for as long as they are on the platform. A background check
that was true five years ago tells you nothing about today. A credential confirmed current
this month tells you what you actually need to know.
