Test card numbers, not real cards
These numbers use each brand's real prefix (Visa starts with 4, Amex with 34/37, and so on) and a correctly computed Luhn check digit, so they pass format validation in payment forms and test suites. They are randomly generated and are not linked to any real account — use them only for development and QA, never for actual transactions. Generation happens entirely in your browser.
