Can I generate test card numbers with BIN 552126?
Yes. Open the generator with this BIN to create Luhn-valid numbers with expiry dates and CVVs for testing forms, validation and BIN-based rules. They are test data: not issued by UniCredit Bulbank AD, linked to no account and declined by real payment systems.
Does a BIN tell me whether a card is valid?
No. A BIN describes a range of card numbers — network, issuer, country and product — not a particular card. Whether a card exists or can be charged is known only to the issuing bank. To check the format of a full number (length and check digit), use the card validator.
A BIN identifies the card network and the issuing institution only. It reveals nothing about an individual card, cardholder or account, and it cannot show whether a card exists or can be charged. Test numbers generated from a BIN are for development and QA only and are declined by every real payment system.
