535251 is the first six digits of a Mastercard card number. The range is attributed to N26 BANK AG in Germany. The BIN (Bank Identification Number), formally called the IIN (Issuer Identification Number), tells payment systems which network and institution a card belongs to.
Issuer BIN ranges are reassigned over time, so always confirm critical decisions with the card network or your acquirer. Want to classify another prefix? Use the BIN checker. Looking for provider-specific test numbers? See the test card numbers reference. Need to validate a full number? Try the Luhn validator.
Issuer and country data on this page comes from the open binlist dataset (CC BY 4.0, merged from iannuttall/binlist-data and venelinkochev/bin-list-data). It is not an official IIN register and may lag bank renames or BIN reassignments.
