IBAN format in Denmark: structure, length and example
An IBAN in Denmark is 18 characters long and always starts with DK. It is a SEPA country, so euro payments from other SEPA members arrive as ordinary domestic transfers. The details below come from the official IBAN registry maintained by SWIFT as registration authority for ISO 13616.
IBANs run from 15 to 33 characters worldwide, so at 18 this one sits below the average of 24. 6 other countries use the same length, which is why the two opening letters matter — they are what tells the sending bank where the money is going. There is no separate branch identifier: the number points at the bank and the account, not at a particular office. The format has been in force since April 2007.

How to send money to an account in Denmark
- Ask for the IBAN in full — including the country code at the front. Spaces do not matter; banks strip them.
- Check the name matches the account. The check digits catch typing mistakes, not wrong recipients.
- Send — and keep the reference number until the recipient confirms arrival.
Common questions
How many characters is an IBAN in Denmark?
18 characters, starting with the country code DK. Written on paper it is normally grouped in blocks of four, like DK50 0040 0440 1162 43.
What does a Denmark IBAN look like?
DK50 0040 0440 1162 43 is the format example published in the official IBAN registry. The first two letters are the country code, the next two are check digits, and the rest identifies the bank and the account.
Do I need a BIC as well as the IBAN for Denmark?
For payments inside SEPA the IBAN alone is enough. Outside SEPA, or when your bank asks for it, you also need the recipient bank's BIC/SWIFT code.
Can I check an IBAN before sending money?
The check digits let any bank detect a mistyped IBAN, but they cannot tell you whether the account belongs to the person you think. Confirm the name and the number with the recipient.
Where this data comes from
Structure, length and examples come from the official IBAN Registry published by SWIFT as registration authority for ISO 13616, snapshot of 2026-08-21. Worked examples are derived from the registry's own sample values. Whether a country is inside SEPA is taken from the European Payments Council list of countries in the SEPA schemes, not from the registry: the registry records the position at its own release date and lags behind admissions.
