Why did we build this?

We're developers - and we wanted to share a tool that's useful for us, with other developers. This is a credit card number generator allows you to test shopping sites, payment forms, or perhaps generate datasets for the next great fintech app you're working on.

If you liked the tool, have some feedback, or perhaps you'd like us to help you out with your fintech project, we're all ears!

What is a Credit Card Number Generator?

It's a simple web-based tool that allows you to generate a completely random, realistic credit card number at the push of a button. You can find credit card generators for nearly any card type, and many for debit cards as well.

Can I buy things with a Card Number Generator?

No. The numbers produced by the Credit Card Number Generator are real, in the sense that they conform to all the rules of a valid credit card number. That includes Luhn's algorithm - see more below. But these numbers aren't linked to any real credit card account, so there's no money for purchases.

What can I do with a Credit Card Number Generator?

You can't buy anything with a random credit card number, but you can use them for a number of other purposes:

  • Free trials - when the trial ends, there's no account to bill; the account will close automatically
  • Testing - developers use fake credit card numbers to validate processes on e-commerce sites and other services
  • Registration - some free registrations require a valid credit card number. Use our credit card generator to get a valid number without disclosing unnecessary personal info.

How does a CC number generator work?

All Front’s credit card generator produces a full set of cardholder and credit card details. The actual number is produced according to Luhn's algorithm, the standard checksum used to produce card validation numbers.
In essence, the generator creates a digital dummy credit card. There's no actual account linked to the number, so it won't pass an active credit card check. The number can be used for verification purposes and testing. All Front’s credit card generator also produces a complete set of credit card details for the various card types.

What is Luhn's algorithm?

Luhn's algorithm is used as a checksum, a way to validate a number by checking the number of the number in a given sequence. Luhn's algorithm is commonly employed in government-issued IDs, as well as by every major credit card company. AMEX (American Express), Visa, and Mastercard all use numbers that follow credit card validation procedures using Luhn's algorithm.

Luhn's algorithm doesn't detect suspicious activity when it comes to credit card numbers but is used for verification purposes. The algorithm detects simple errors and can therefore identify a valid card from an invalid one. The same process works for debit cards as well as other products like government-issued IDs.

Are Credit Card Number Generators illegal?

Simple card generator tools like All Front’s fake card generator aren't illegal. Luhn's algorithm is in the public domain, and simply creating a number isn't illegal. Nowadays all card transactions are processed and validated within seconds, and attempting to use a number from the card generator in a production online checkout for a real transaction is not going to work. In addition, there are a number of processes that require a credit card validator for testing purposes.

The cardholder credit card details created with the credit card number generator are all random, and the credit card issuers aren't associated with the tool.
