![]() The samples are from PayPal and may be found here: Algorithm Overview One final note - any card numbers used here for illustration / example are fictitious - these pass the MOD 10 check, but are not real credit card numbers, only samples. I will also show you a method to remove 'noise' from the number - for example, spaces or leading/trailing characters. In the following sections I will provide a step-by-step guide to validating these numbers by hand, then show how we can replicate this as a User-Defined Function (UDF) within SQL Server. In the Next Steps section at the end of this tip. Luhn's Algorithm, links for which are provided It has no cryptographic validity, but it is a useful rule-of-thumb check that can be used to validate that a card number is correct, and can be used in its opposite form to generate account (and credit card) numbers - to help discourage potential fraudsters, this function is NOT covered here. Kickstart your coding journey now.The industry standard for checking credit card numbers for validity is known in colloquial terms as the 'MOD 10 Check', or more formally as Luhn's Algorithm.
