PAN Luhn check

Client

PAN Luhn check focuses on the primary account number checksum used before tokenization or authorization requests. Paste digits for mod-10 pass/fail—also available generically at /tools/luhn.

PAN vs token

Gateway tokens and last-four displays cannot be Luhn-checked. Paste full test PAN digits only—never live customer cards on untrusted devices.

Sensitive data: checks run only in your browser. Prefer processor-published test card numbers, never live PANs on shared devices.
?

Spaces and dashes are stripped before counting digits and running Luhn. Card-network labels come from common public BIN/IIN ranges—they may mismatch exotic co-branded or new ranges.

16 digits after cleanup

Likely network: Visa

Luhn checksum: passes — algorithm-only; does not mean the card is active or genuine.

Common use cases

  • Validate PAN column in mixed identifier spreadsheets.
  • Document Luhn requirement in internal API specs.

Common mistakes to avoid

  • Validating token or last-four only

    Luhn requires the full digit sequence—not masked tokens.
