One BIN per bank — the most common Visa or Mastercard product of each of the largest issuers, plus local-network BINs. All 536 BINs with a named issuer are in the Denmark BIN list.

Local card networks in Denmark

Besides the international networks, Denmark has its own card schemes. Local networks matter for testing because their numbers often use prefixes that a Visa/Mastercard-only form rejects or labels wrongly.

Payment testing notes for Denmark

Generated numbers only pass format checks: network prefix, length and the Luhn checksum. They are not issued by any bank in Denmark, carry no money and are declined by every real payment system — use them for forms, validation and BIN rules, and switch to your gateway's documented test cards for approvals and declines.

Frequently asked questions

Can I generate a Denmark credit card number for testing?

Yes. The generator on this page starts every number with a real BIN registered to a bank in Denmark — by default 515518 (Bokis, Mastercard debit). The remaining digits are random and the last one is a Luhn check digit. No bank issued the number, so it carries no account and real payments with it are declined.

Which card networks are most common in Denmark?

By BIN count in our data: Maestro 41%, Mastercard 21%, Visa 15%, Visa/Dankort 9%. Local networks: Dankort (100 BINs), Visa/Dankort (100 BINs). Debit ranges make up 79% and credit ranges 21%.

Which BINs do Visa cards from Denmark start with?

Examples from different banks: 443256 (Nordea Bank Danmark A/S); 405245 (Jyske Bank A/S); 464256 (Vestjysk Bank A/S); 405833 (Sydbank A/S). See the Denmark BIN list for every bank.

Which currency should I use to test payments from Denmark?

DKK (Danish krone). Gateway APIs usually expect amounts in the smallest unit (for example 1050 for 10.50). A card from any country can pay in any currency the merchant supports; the issuer handles conversion.

Will these numbers pass a payment gateway?

They pass format checks — length, network prefix and the Luhn checksum — so they are ideal for testing form validation and BIN-based rules. Gateways in test mode want their own documented test cards for approvals and declines; in live mode every generated number is declined because no bank has issued it.
