Understanding the SSN
The Social Security number (SSN) is a 9-digit number issued by the United Sates of America to citizens, permanent residents, and temporary (working) residents under section 205(c)(2) of the Social Security Act, codified as 42 U.S.C. § 405(c)(2). The number is issued by the Social Security Administration to an individual. Its primary purpose is to track individuals for taxation purposes. In recent years the SSN has become the industry accepted national identification number
What you need to Know
- Congress has proposed federal laws that will restrict the use of SSNs for identification and ban their use for a number of commercial purposes, e.g. rental applications.
- There is no law requiring a U.S. citizen to apply for a Social Security number to live or work in the United States; however, it is required for parents to claim their children as tax dependents. It should be noted that the liklihood a person does not have a SSN in the USA is very slim, since most financial activties require the use of one.
- The Social Security number is a nine-digit number in the format "123-45-6789". The number is divided into three parts.
- The Area Number, the first three digits, is assigned by the geographical region. Since 1973, when SSA began assigning SSNs and issuing cards centrally, the area number assigned has been based on the ZIP code in the mailing address provided on the application for the original Social Security card. The applicant's mailing address does not have to be the same as their place of residence. Thus, the Area Number does not necessarily represent the State of residence of the applicant, neither prior to 1973, nor since.
- Currently, a valid SSN cannot have an area number above 772, the highest area number which the Social Security Administration has allocated.
- The middle two digits are the group number. They have no special geographic or data significance but merely serve to break the number into conveniently sized blocks for orderly issuance.
- There is a theory that the two middle digits can be used to identify a person's ethnic background. This is debunked as an urban legend on the Social Security Administration's website.

- The last four digits are serial numbers. They represent a straight numerical sequence of digits from 0001-9999 within the group.

- Numbers of the form 666-xx-####.
- Numbers from 987-65-4320 to 987-65-4329 are reserved for use in advertisements.

- When a person dies the SSA publishes this fact, as the SSN is released to the public domain, this list is over 79 million records long, and can be checked manually for free at Rootweb.com, look for the SSDI, or social security death indicator.
- There are also special numbers which will never be allocated:
- Some third party vendors include the SSDI indication with their service.
