Validate BIN Checker

Validate a BIN/IIN (6–8 digits) or paste full card numbers to extract the BIN, check basic format rules, guess the card network from common prefixes, and optionally verify the Luhn checksum for card numbers.

Category: Data · URL: /tools/validate-bin-checker.html
Notes: Network detection is a prefix-based guess and may be incomplete. BIN validation here checks format/length; it does not confirm issuer/bank/country.
Privacy: runs locally in your browser. No uploads, no tracking scripts.

How to use

Paste one BIN or card number per line. The tool outputs a compact TSV table you can copy into Excel/Sheets.

  1. Paste BINs (6–8 digits) or full card numbers (13–19 digits) into the input.
  2. Keep Luhn check enabled if you want checksum validation for card numbers.
  3. Click Validate to get a TSV result (Status, BIN, network guess, etc.).

FAQ

What is a BIN (IIN)?

A BIN/IIN is the first 6–8 digits of a payment card number that identifies the issuer range and helps route transactions.

Does this tool do a BIN lookup for bank/country?

No. It validates format/length and makes a best-effort network guess from common prefixes; it does not identify bank, country, or product.

What BIN lengths are supported?

It accepts 6-digit BINs and (optionally) 8-digit BINs. Full card numbers are accepted if they are 13–19 digits.

If Luhn passes, is the card number valid?

No. Luhn only checks a checksum; it cannot confirm that a number is issued, active, or allowed.

Can I validate multiple values at once?

Yes—paste one BIN or card number per line. The output is TSV so it’s easy to copy into spreadsheets.

Does the tool send my input to a server?

No. Validation runs locally in your browser and does not make network requests.

Why does the network show as “Unknown”?

The tool only checks a limited set of well-known prefix rules. Many ranges are issuer- or region-specific and won’t be detected.
