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.
After doing quite a bit of research I uncovered a pretty thorough list of all possible test credit card numbers and test check numbers used for testing purposes. Why is this interesting?hello.. i want to buy subscriptions online, nothing physical that would be shipped to me… i need a valid credit card number with exp. date, ccv, and card holder info.. can somebody PLEASE email me some numbers??? email@example.com
Normally a "real" credit card check takes about 10 seconds (against a cc db). I seems there is a fast first credit card number check, which "finds out" the credit card number itself is not valid. Maybe this is a hint from above, and we should do only iPhone and Android development of our apps, and skip WinPh7 Hello Ben, thank you for the fast reply. No, i didn't try it multiple times BEFORE I got the message. At the first time i entered a valid credit card number the message appeared.xboxforums.create.msdn.com
Second, all credit card numbers must pass the Luhn algorithm. This requirement restricts the set of valid credit card numbers to a small subset of all possible strings of numbers. It's a simple test that a valid credit card number will pass but that an invalid card will probably not pass. This is how online stores that accept credit cards can reject a credit card number with a typo very efficiently.bradconte.com
