Are these real credit card numbers?

No. They are randomly generated test numbers that only satisfy the format and Luhn checksum. They are not linked to any account, carry no funds and cannot be used to pay for anything.

Why do they pass validation?

Payment forms check the card brand prefix, length and the Luhn checksum. These numbers are built to satisfy all three so you can test your validation logic.

Can I use these to make a purchase?

No. They will be declined by any real payment processor. They exist purely for testing and development.

About the Credit Card Number Generator (Test)

Developers and testers need card numbers that pass a payment form's format and checksum checks without using a real card. This tool creates them.

Each number matches the chosen brand's prefix and length and passes the Luhn checksum, so it is accepted by validation code while carrying no funds and belonging to no one.

They are for testing input validation only and cannot be used for payments.
