FAQ
Do these card numbers work for real purchases?
No. They are only valid according to the Luhn algorithm and are meant exclusively for testing. No bank is attached to them and no real transaction is possible.
What is the Luhn algorithm?
It is a checksum formula used to validate identification numbers such as bank cards. It catches typing errors but does not guarantee that a card actually exists.
Is it legal to generate these numbers?
Yes, as long as they are used only to test software. Using card numbers to deceive a payment system or commit fraud remains illegal.
