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 Validation - Check Digits. This document outlines procedures and algorithms for Verifying the accuracy and validity of credit card numbers. Most credit card numbers are encoded with a "Check Digit". A check digit is a digit added to a number (either at the end or the beginning) that validates the authenticity of the number.web.eecs.umich.edu
Validating credit card numbers is the ideal job for regular expressions. They're just a sequence of 13 to 16 digits, with a few specific digits at the start that identify the card issuer.And if your card processor charges for failed transactions, you'll really want to implement both the regex and the Luhn validation.

Using Basic Text Input for Card Number. Regular text inputs don't prevent many errors that occur during the clumsy process of entering credit card numbers. While glancing from credit card to keyboard to screen, it's easy to lose position in a long string of numbers, drop digits, and add additional characters. Example: Text inputs also allow illegal characters like letters, requiring delayed validation to warn users instead of just ignoring these characters.creditcardjs.com
