About BIN lookups and card validation
A BIN lookup uses only the first 6–8 digits of a card number — no full card data is required or transmitted. From these digits alone, Versys can identify the card scheme (Visa, Mastercard, Amex, Discover, Maestro, etc.), the issuing bank, the card type (credit, debit, prepaid, corporate), and the country of issuance. Combined with a Luhn algorithm check on the full card number, this gives a comprehensive picture of a card's validity and origin. Learn more on the BIN Lookup Guide.
