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.
Ads by Google. You may have heard before that credit card numbers follow a certain pattern and structure so that they can be validated before a transaction is accepted. However, it’s one thing to know that the structure is there and another thing entirely to understand how credit card numbers work.www.makeuseof.com
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. You can’t buy anything with these.www.darkcoding.net
A credit card has a maximum of 19 digits, though most use 16, meaning that there are typically 9-12 digits utilized for account numbers. Mathematically, this means that there are 10**9 possible account numbers, or a billion possible combinations. If the card issuer used 12 digits, that’d be 10**12 or 1,000,000,000 000 combinations. That’s a lot of possibilities! 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
