A page from the Fake Name Generator that checks a credit card number's network, length and Luhn check digit. It explains the Luhn check step by step and offers sample made-up numbers for testing forms. The page notes the sample numbers are not accounts and are declined by payment gateways.
A page that checks the format and prefix rules of UK National Insurance numbers and provides sample NI numbers for testing forms. It explains how a NINO is built and states that NINOs have no check digit, so a correctly formatted number may never have been issued.
Nano ID CC is a collision calculator for Nano ID, a library for generating random IDs. It helps estimate how much an ID length can be reduced, given a chosen alphabet, ID length and generation speed, to keep the probability of at least one duplicate low.
A page from the Fake Name Generator that validates US bank ABA routing numbers, checking the prefix and check digit. It explains the 3-7-1 check step by step and provides sample routing numbers for testing forms. The samples pass the tests but are otherwise random.
A generator that produces random, fictional identities including names, addresses, phone numbers, emails, usernames and passwords, described for software testing, sample data and writing. It is free and needs no account; signing in allows saving identities, bulk orders and API use. An API returns identities as JSON repeatable with a seed.
A page from the Fake Name Generator that checks whether a US Social Security number follows Social Security Administration numbering rules. It explains how SSNs are built and how numbering changed in 2011, and provides sample SSNs for testing forms. The page notes that numbers following the rules may still never have been issued.
A browser-based tool that generates South African ID numbers, labeled as fake on the page. A form is submitted to obtain a generated number, and the page links to Wikipedia, an article and the source code for further information.
