Frequently Asked Questions

Is Dankort a credit or debit card?

Dankort is primarily a debit card. However, many Dankort cards are co-branded with Visa, allowing them to function as international debit cards outside of Denmark.

What is the Dankort prefix?

Standard Dankort numbers always begin with the four digits "5019". If it's a co-branded Visa-Dankort, it will follow the Visa prefix (starting with "4").

How does the validator work?

The validator checks if the number starts with 5019, verifies that it is exactly 16 digits long, and applies the Luhn algorithm to ensure the checksum is correct.
