Denmark IBAN Format, Length and Example

How to read this Denmark IBAN

• The value starts with DK, the IBAN country code for Denmark.
• The next two characters are international check digits.
• The remaining 14 characters are the country-specific BBAN section: 14 digits after the country code and check digits: a 4-digit bank identifier, 9-digit account number, and 1 check digit.
• Danish IBANs are 18 characters long and use a numeric BBAN in the example shown here.
• The short length means extra digits from invoice references should be easy to catch.

Result interpretation

Passing format checks still does not confirm a real account, owner, bank reachability, or payment success.

What the format check reviews

• Whether the IBAN starts with the DK country code.
• Whether the IBAN has 18 characters after normalization.
• Whether the value uses allowed letters and digits.
• Whether the MOD97-10 checksum is valid.

Common Denmark IBAN mistakes

• Adding a reference number after the DK IBAN when copying an invoice line.
• Treating SEPA country context as proof that a specific Danish account can receive a payment.

When this page is useful

• Checking a Danish IBAN before running a separate payee or payment-provider confirmation.
• Separating the compact DK value from invoice notes before validation.
• Use the IBAN Checker after this page when you need a local checksum result for one value.

What it cannot confirm

• Format checks do not confirm that the account exists or belongs to the intended payee.
• They do not confirm bank reachability, payment readiness, or payment success.
• Use the detailed disclaimer for the full list of non-verified items.

Denmark SEPA context

The local SEPA country reference data lists this country as: SEPA country - EU. Country-level SEPA status does not confirm that a specific bank or account can receive a payment.

Limitation note

This page explains IBAN format rules only. It is not a bank, account, sanctions, fraud-risk, or payment-network check.

Before using this IBAN format for payment

A structurally valid IBAN can still be wrong for a real transfer. Always verify payment details with the invoice issuer, recipient, bank, or payment provider before sending money.
