⚠ For testing form validation, UI and QA fixtures only. Generated numbers pass the Luhn check but are random — they are not real accounts and will be declined by any live payment system. To test real payment flows use a provider's official sandbox cards.




Diners Club card number format
Diners Club numbers start with 300–305, 36, 38, have 14 digits and a 3-digit security code. The last digit is a Luhn check digit, which lets forms catch typos before sending the card to the payment provider.
FAQ
How many digits does a Diners Club card have?
14 digits, with a 3-digit security code.
Are generated card numbers real?
No. They follow the brand's prefix and length rules and pass the Luhn checksum, so they look valid to front-end validation, but they are random and not linked to any bank account. Any real authorization will fail.
What can I use them for?
Testing checkout form validation, input masks and brand detection, filling QA databases and fixtures, UI screenshots and demos, and load-testing tools that only need well-formed numbers.
Can I use them in Stripe or Adyen test mode?
Usually no — sandboxes only accept their own published test numbers. Use our test cards list for gateway testing.
