A database for looking up PIC/CIC (Carrier Identification Code) codes, which can be searched by code, ACNA, company name or location. A PIC or CIC code is a 4-digit prefix that identifies a long distance carrier in North America or the Caribbean to a LEC, which uses the code to route calls. The database is updated daily from the NANPA list.
A one-step page for decoding Social Security Numbers issued prior to June 25, 2011. It points to an article on the structure of Social Security Numbers and to the Social Security Administration website for later number assignments. It also points to the Internal Revenue Service website for the structure of Individual Taxpayer Identification Numbers. The page was automatically updated monthly through June 2011 and has been static since.
A page for checking a vehicle identification number's characters and check digit, explaining the step-by-step check, reading the model year, and offering sample VINs for testing forms. It describes how a VIN is built, letter values, model year codes, and includes PHP check code.
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.
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 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 for checking Canadian social insurance numbers, verifying the first digit and Luhn check digit, showing the step-by-step check, and offering sample SINs for testing forms. It also lists what the first digit means and includes PHP and JavaScript check code.
