Does the Danish check need the seafarer's date of birth?

No. The STCW certificate service asks for the certificate number only. Norway and the United Kingdom ask for a date of birth; Denmark does not.

Can I see the actual certificate on verify.dma.dk?

Yes. After a successful lookup the service lets you open a copy of the certificate to view all details.

Does verify.dma.dk cover Danish medical certificates?

Yes, under its own Medical certificate branch on the landing page. That branch is separate from the STCW check Docka runs.

Is the Danish service in English?

Yes. The site loads in English with a DA switch for Danish.

Why did Docka return not found for a Danish certificate?

The number was not recognised by the service. Check the digits against the document and retry on the portal. Only Søfartsstyrelsen can say why a genuine certificate is missing from its register.

Verify a Danish seafarer certificate

Last updated: 7 September 2026

By the Docka team · Reviewed 7 September 2026

To verify a Danish seafarer certificate, type the certificate number into the STCW certificate service at verify.dma.dk, the online verification service of Søfartsstyrelsen (the Danish Maritime Authority). Docka submits that number for you and returns the portal's answer, live.

The Danish check is one of the simplest Docka runs: one number, no date of birth, no seafarer ID.

Authority: Søfartsstyrelsen, Danish Maritime Authority. Official verification portal: verify.dma.dk. English, with a Danish (DA) switch.

What Docka confirms

The check goes to Søfartsstyrelsen's own service at verify.dma.dk, the flag-state source for STCW certificates issued by the Danish Maritime Authority.
One input: the Certificate number as printed. Nothing about the holder is sent.
The check is live and automatic. Docka records the answer with a timestamp so a port state control (PSC) inspector sees when the register was asked.
Docka reports the validity answer the service returns.

What the portal asks for

Input	Required
Certificate number	Yes

Do it yourself on the official portal

Open verify.dma.dk. The landing page offers three services: STCW certificate, Ship certificate and Medical certificate. Choose STCW certificate.
Enter the Certificate number in the single box and press Verify.
Read the result. The service states whether the certificate is valid and shows basic information from it. A copy of the certificate can be opened from the result to compare every detail with the paper in front of you.

What to watch for

The Danish Maritime Authority publishes no cut-off year on the service, and Docka has no coverage caveat to add for Denmark.
The service is in English with a DA switch for Danish, top right. The English wording quoted on this page is the portal's own.
A number the service does not know returns no certificate. Docka passes that on as not found. It is not a fraud finding on its own; a typo in one digit produces the same answer.

What the portal says about itself

The STCW certificate page opens with the reason the service exists: the STCW Convention requires that certificates and endorsements can be verified at the issuing administration. The Danish Maritime Authority built this service to prove the validity of the STCW certificates it issues.

That sentence is the whole argument for primary source verification. The issuing administration holds the record. A PDF, a stamp or a laminated card is a copy of it.

Certificate copy versus validity answer

The Danish result has two layers. The first is the validity statement with basic certificate data. The second is a viewable copy of the certificate itself.

For a crewing manager the first layer is usually enough. For a PSC inspector who suspects an altered document, the second layer settles it: compare the copy the register holds with the copy the seafarer carries.

Docka's automatic check works from the validity layer. If you need the register's copy, open the portal yourself with the same number.

Ship and medical certificates on the same portal

verify.dma.dk also verifies ship certificates and seafarer medical certificates. Docka's Denmark connector covers the STCW branch. For the other two, use the portal directly.

If a candidate shows a Danish medical certificate, open that branch on the portal and check it there. Docka's automatic result for Denmark speaks only to the STCW certificate number you entered.

How Docka labels the result

Every document in Docka carries one of four levels. The level says how far the check reached, and a lower level is never rounded up.

L0 Self-uploaded, not yet verified: Self-uploaded, on file, but not yet checked or verified by anyone.
L1 Reviewed by staff: A human reviewer opened the actual document and confirmed it, holder-bound to this person, not a government registry check.
L2 Registry-confirmed: The document was confirmed to exist in a registry, but the holder's identity was not verified (holder-bound to the document, not the person).
L3 Government-verified: Verified against the issuing government's maritime registry.
