By knowing just the first three digits of someone's SSN, you can correctly guess their birthstate. The nine-digit SSN hasbeen used since 1936 to track a person's wages for the purpose of accruingbenefits with the Social Security Administration. The SSN has 3 sections.
Area Numbers
The first three digits ofthe SSN are called the area numbers. This is because they originally corresponded to the state that a personlived in at the time they were issued their SSN.
Beginning in 1972, thearea numbers began being assigned based upon the zip code in the mail addressto which the individual requested his or her card to be sent. Thus, it is possible for someone to reside inone state but ask that the card be returned to another states, thus renderingthe area number less than area specific.

Group Numbers
Digits four and five inthe SSN are referred to as group numbers. They identify the block of numbers currently being issued. As an example, the SSNs 123-01-0001 through123-01-999 would all be issued before moving on to the next group number.
Serial Numbers
Digits six through nineare known as serial numbers. They areissued consecutively from 0001 to 9999.
By dissecting someone'sSSN you can learn the state in which they lived when they applied for the numberfor those SSNs issued prior to 1972 and the state noted in the return addressfor those applied for after 1972.
In some cases, letters mayappear after a social security number . For example, I have a California death certificate that reports a social security number with an "A"appended to the end of the number. For example:"000-00-0000A."
The Social Securitynumber followed by one of these codes is often referred to as a claimnumber. The SSA assigns these codes once someone applies forbenefits. These letter codes may appear on correspondence fromSocial Security or on a Medicare card. They will never appear on a SocialSecurity card.
For example, if thewage earner applying for benefits and your number is 123-45-6789, then theirclaim number is 123-45-6789A. This number isalso be used as their Medicare claimnumber, once they become eligible for Medicare.
