Bank Card BIN Lookup
Detect issuers, card types, and networks; validate full numbers and export batch results. Runs locally—nothing uploaded.
Card BIN / IIN analysis
Detect the card network, prefer the local database covering 23 major Chinese issuers, and validate full card numbers.
The global add-on database covers the current locale regions, Latin America, Brazil, Germany, Russia, and France. Only the first 6 / 8 BIN digits are used.

Enter a full card number to also run a Luhn checksum.
Browser-local processing
Loads only the needed 6 / 8-digit BIN shard and does not call third-party live BIN APIs, so full card numbers are not sent externally.
Detection and validation
The network is detected from number ranges; full numbers are checked separately with Luhn.
6- and 8-digit support
Shows both the traditional 6-digit BIN and the modern 8-digit IIN for comparison.
