The fastest free BIN/IIN lookup service on the web.
BINVault provides free, instant, and accurate Bank Identification Number (BIN) lookups to developers, fraud analysts, payment processors, and curious users worldwide.
We maintain a database of over 400,000 BIN records, updated monthly from multiple verified sources. Every lookup is processed locally — we never forward your data to third-party services.
Our BIN database is compiled from publicly available payment industry sources and updated monthly. While we strive for accuracy, BIN data can change as banks reissue cards.
If you find an incorrect BIN record, please contact us and we will investigate.
We take your privacy seriously. We only read the first 6–8 digits of any card number you enter. We do not store full card numbers. We do not sell data. See our Privacy Policy.
