Quoting SSN Generator

SSN Generator or Social security number generator is a web-based tool that generates random SSN for programmers and testers for testing who constantly need to enter different SSNs on websites over the internet

It generates a Social Security number divided into three parts in the " AAA-GG-SSSS " format, the standard SSN format.

The first three digits are assigned by geographical region in the united state, and the middle two digits are the Group Number. The last four digits are Serial Numbers.

All the numbers are generated randomly using a random number generator algorithm where Numbers with all zeros in any digit group (000-##-####, ###-00-####, ###-##-0000) and numbers with 666 or 900-999 in the first digit group are not allocated.
