Our credit card generator uses sophisticated algorithms and industry-standard rules to create valid test credit card numbers. Here's a detailed breakdown of how the process works:
First, the generator starts with the correct prefix for each card type:
After the prefix, the generator creates random digits to complete the card number, following specific length requirements for each card type:
The generator applies the Luhn algorithm (also known as the "modulus 10" algorithm) to ensure the number is mathematically valid. This is the same validation used by real credit card issuers.
The generator also creates:
Generated card data can be exported in multiple formats:
While our generator creates mathematically valid numbers, they are strictly for testing purposes. These numbers cannot be used for real transactions and do not represent actual credit card accounts.
