A valid SSN is formated like this: xxx-xx-xxxx. The first three digits have to do with zip code of the person's place of birth. Prior to 1973 it was the local Social Security field office number.
* The first three digits will never be "000". * The first three digits will never be above "770". The next two digits are the Group number, which has to do with the order in which SSN's are issued within a particular geographical area. * The next two digits will never be "00". The last four digits are the serial number of the individual. Based upon the other two codes, there can only be a possible "high number" at any point in time. A list of those high numbers can be found here: http://www.ssa.gov/foia/highgroup.htm * The last four digits will never be "0000".
