Structure of a Danish IBAN

The IBAN for Denmark (DK) consists of a total of 18 characters and follows a clearly defined standard:

• DK - two-letter country code for Denmark
• 2 check digits - used for mathematical validation

How does the IBAN check work for Denmark?

Our IBAN Validator checks the Danish IBAN based on internationally defined ISO standards:

• Verification of the correct IBAN length (18 characters)
• Validation of the country code "DK"
• Calculation of check digits using the Modulo 97 method

The check exclusively confirms the formal validity of the IBAN. Verification of the account holder or account status is technically not possible.
