Leading digits come from the published sandbox prefixes (Visa: 411111, 424242, 400000, 401288; Mastercard: 555555, 510510, 545454, 222300; American Express: 378282, 371449; Discover: 601111, 601100; JCB: 353011, 356600); the middle digits are seeded-random and the final digit is the Luhn check digit. TEST VALUES ONLY. These are built from the sandbox BIN prefixes that payment processors publish for development. They satisfy the Luhn checksum and a checkout form’s format checks, they belong to no cardholder, they hold no funds, and a live acquirer declines them — they are not real accounts and cannot become real accounts. Never put a real card number into test data.

One number per line. Duplicates are filtered out, so every row is distinct.

The brand decides the leading digits and the length. Both are part of the ISO/IEC 7812 numbering scheme, not a formatting choice.

The published list is short but universally recognised by test modes. The randomised mode keeps the same leading digits and fills the rest, which is what you want for bulk fixtures.

The same seed always returns the same list, so a shared link shows what you saw. Ignored when you ask for the published numbers only.

Về số thẻ tín dụng để thử

Every card number you have ever typed ends in a digit that exists only to catch mistakes. The scheme behind it came from Hans Peter Luhn (1896–1964), a German-American researcher at IBM who was awarded more than eighty patents and who also gave information science Key Word in Context indexing and selective dissemination of information. His check-digit method reached the US Patent Office as patent 2,950,048, "Computer for Verifying Numbers", granted on 23 August 1960. The patent is for a small hand-held mechanical device that worked out the mod-10 sum for you; the doubled-and-reduced substitutions were not computed by the machine at all but simply printed in permuted order on its body. The algorithm went into the public domain and is now specified in ISO/IEC 7812-1.

Card numbering grew up around it. Diners Club issued the first widely accepted charge card in 1950 and BankAmericard followed in 1958, but it was ISO/IEC 7812, first published in 1989, that fixed what the digits mean: a leading major industry identifier, an issuer identification number of six digits — extended to eight in the 2017 revision — then the account identifier, then Luhn's digit. The register of issuer numbers is held on behalf of the American Bankers Association, with CUSIP Global Services taking over its administration in February 2024. When Mastercard ran short of room in its 51–55 block it announced a new 222100–272099 range on 3 November 2014, and those numbers went live on 14 October 2016 — which is why a well-maintained test suite now includes a 2-series card.

Test numbers themselves are a convention, not a standard. PCI DSS keeps live card data out of development environments, so every processor publishes a sandbox set, and a handful became universal through sheer repetition across gateway documentation. Nobody reserved them the way telephone numbering reserves drama numbers; they are simply numbers that were never issued, so that nobody's real card ends up in a fixture.

Tính chất chính

  • TEST VALUES ONLY — every number here is built from a BIN prefix published for sandbox use, corresponds to no cardholder and no funds, and is declined by live acquirers. It is not a real account and cannot become one.
  • Each value passes the Luhn check: double every second digit from the right, subtract 9 from any result above 9, sum everything, and the total is a multiple of 10. The last digit is the check digit.
  • The first digit is the major industry identifier — 3 is travel and entertainment, 4 and 5 are banking and finance. Visa begins with 4, Mastercard with 51–55 or 2221–2720, American Express with 34 or 37, Discover with 6011, 644–649 or 65.
  • Payment card numbers run from 8 to 19 digits. This page emits 16 for Visa, Mastercard, Discover and JCB and 15 for American Express, the lengths those brands use for ordinary consumer cards.
  • Luhn catches every single-digit error and nearly every swap of two adjacent digits, but not 09 ↔ 90, and not the twin errors 22 ↔ 55, 33 ↔ 66 or 44 ↔ 77.
  • Zero-padding a number on the left never changes its Luhn result, because the algorithm counts positions from the right and leading zeros add nothing to the sum.
  • The issuer identification number is the leading six digits, extended to eight by the 2017 revision of ISO/IEC 7812-1; the account identifier sits between it and the check digit.
  • A Luhn pass is not proof of anything about an account. Only an authorisation request to the issuer can establish that a card exists and has funds.
