BIN Checker — Validate Card Numbers & Lookup Issuer

Free online BIN checker with Luhn validation. Enter a credit or debit card number to verify the checksum, identify Visa, Mastercard, Amex, and Discover brands, and get bank issuer details instantly.

How the BIN checker works

Paste the first six digits or a full card number. Binlyx validates the Luhn algorithm, performs a bank identification number lookup, and returns issuer, country, card type, and category. Results are cached at the edge for faster repeat lookups.
