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.

Credit card numbers that conform to the Luhn formula (MOD 10 check). Usefull for testing e-commerce sites (because they should get past any pre-validation you do, and be declined at the card processor or bank stage). In testing situations any expiry date within the next 3 years should work. Feedback forces me to clarify this: These are NOT valid credit card numbers.www.darkcoding.net
I mistyped a digit on my credit card last time I was shopping online and the site promptly told me the card number was invalid. But there’s no way it had time to check with the bank. Is there some secret coding system for credit card numbers that they used, and if so, what’s the scoop?The last digit is perhaps the most interesting, however, it’s the checksum and it’s a bit tricky to calculate but here’s basically how it works: Take your credit card number and double every other digit, starting on the right.www.askdavetaylor.com
