A valid credit card number has several fields and each of them has a meaning. For the technically inclined, this number complies to the ISO 7812 numbering standard. An contains a six-digit issuer identification number (IIN), an individual account identification number, and a single digit checksum.
The credit card numbers you generate on this page are completely random. When we say they are valid, we merely imply that they are a possible combination of characters which will validate when passed through the MOD 10 algorithm. You can also generate valid credit card numbers for specific Issuing Networks by utilising their particular prefixes. However, we do not provide you (obviously) with the correspondent verification code for these cards, as they are completely fake and made up randomly.
If you've ever found yourself trying to try a product online which required a credit card, even when you just want to take a look, you know why we made this. We believe there's no need to share such information with providers without the actual intent to buy stuff. Anyone can make a website with a form and require you to insert valuable and sensitive information which requires you to give up your privacy. This is a way to protect yourself in such situations.
The other reason we made this are programmers testing ecommerce websites, applications or other software. They usually need lots of fake data, and this is a very easy way to generate a bunch of valid credit card numbers in a split second. There's another tool for those times when you need to generate all other kinds of data.
Get them from darkcoding-credit-card on github, or Download (zip) all versions. If you want to go one step further and generate a whole test identity, try the Fake Name Generator. It makes use of this credit card generator, and adds a lot of other identity data.I never understood why people didn’t realise that a number that obeys mod10 does not suddenly give you a credit card account. There’s lots of obvious (and also some subtle) bits and pieices missing so a wannabe skiddie is never going to get very far armed with just an algorithm and a load of not so random numbers.www.darkcoding.net
If you thought the sprawl of 16 numbers across the front of your credit was randomly generated, think again: like any good string of numbers, an algorithm was involved in its creation. In fact, the first couple of numbers relate to the kind of card it is: Visas start with a 4, Mastercards a 5, Amex a 34 or 37.This provides a small amount of protection from hackers or poorly educated crooks who might attempt to randomly generate and guess credit card numbers.gizmodo.com
