SSN Numbers

[Kinito_2k3 5]

Alright guys, I am calling the Math lovers here.

A SSN is composed of 10 figures, which means that there is 3 628 800 unique permutations. Now, there is over 300 000 000 persons in the US, and probably over twice that double having an american SSN...

My question is simple, I thought that the SSN was a unique identifier for a citizen/alien? Am I wrong? Surely yes

My other guess is that, the unique identifier is a composition of SSN+DOB at least, maybe SSN+DOB+SEX which would mean that there would potentially be 3 628 800 to 7 257 600 available SSN per day?

Now, in the unlikely eventuality that 3 628 801 baby born 01/01/1975, all males or all females want to obtain a SSN, how would the SSA address the issue?

Or maybe I am missing the point Just some food for thoughts, it's saturday night and I had a few booz

Any constructive comments/solutions?

10? I think an SSN has only 9 digits but then again I'm not good with math.

ssn's could range from 000-00-0000 to 999-99-9999

That would make 1,000,000,000 possible numbers. If need arises, they could always add another digit.

True Darn it

The Social Security number is a nine-digit number in the format "AAA-GG-SSSS". The number is divided into three parts.

The Area Number, the first three digits, is assigned by the geographical region. Prior to 1973, cards were issued in local Social Security offices around the country and the Area Number represented the office code in which the card was issued. This did not necessarily have to be in the area where the applicant lived, since a person could apply for their card in any Social Security office. Since 1973, when SSA began assigning SSNs and issuing cards centrally from Baltimore, 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.

Generally, numbers were assigned beginning in the northeast and moving south and westward, so that people on the east coast had the lowest numbers and those on the west coast had the highest numbers. As the areas assigned to a locality are exhausted, new areas from the pool are assigned, so some states have noncontiguous groups of numbers.

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.

The group numbers range from 01 to 99. However, they are not assigned in consecutive order. For administrative reasons, group numbers are issued in the following order:

ODD numbers from 01 through 09

EVEN numbers from 10 through 98

EVEN numbers from 02 through 08

ODD numbers from 11 through 99

As an example, group number 98 will be issued before 11.

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

This is wrong too since some are reserved use and some are not to be used...read the thread! This is more complex than what I thought :0

Math Is Easy - Will The US Ever Run Out Of Social Security Numbers!

The Social Security number is composed of a 3 digit area number, a 2 digit group number and a 4 digit serial number; a serial number is a unique number. The total Social Security numbers that can exist is based on the number of area numbers, group numbers and serial numbers possible. The 10 digits used for a Social Security number are 0,1,2,3,4,5,6,7,8,9. How many area numbers, group numbers and serial numbers are possible? We use math to find the answer.

Please refer to another article on this site for the details of how each group of numbers is determined for a phone number; the mehtod is the same for the social security number.

Why Does My Telephone Area Code Have To Change!

Using the methods of math we can have 10 X 10 X 10 or 1,000 possible 3 digit area numbers, 10 X 10 or 100 possible 2 digit group numbers, and 10 X 10 X 10 X 10 or 10,000 possible 4 digit serial numbers.

Due to Social Security Administration regulations certain numbers within each category are not currently available to use:

* area numbers between 734 and 749, or above 772

* numbers with all zeros in any digit group

* area number 666

* numbers from 987-65-4320 to 987-65-4329 are reserved for use in advertisements

Area numbers not available are:

734 - 749 for a total of 16

772 - 1000 for a total of 229

000 for a total of 1

666 for a total of 1

The total number of area numbers not available is 247.

The total of 1,000 possible 3 digit area numbers is reduced by 247 to 753.

Group numbers not available are:

00 for a total of 1

The total number of group numbers not available is 1.

The total of 100 possible 2 digit group numbers is reduced by 1 to 99.

Serial numbers not available are:

0000 for a total of 1

The total number of serial numbers not available is 1.

The total of 10,000 possible 4 digit serial numbers is reduced by 1 to 9,999.

In summary, there are 753 possible 3 digit area numbers each of which can have 99 possible 2 digit group numbers and each of these can have 9,999 possible 4 digit serial numbers. So 99 group numbers X 9,999 serial numbers = 989,901 possible numbers for each possible area number; then 989,901 X 753 area numbers = 745,395,453 possible social security numbers. We then have to reduce this total by numbers from 987-65-4320 to 987-65-4329 or 10, so 745,395,453 - 10 = 745,395,443 possible social security numbers currently available.

As the population of the US increases, the demand for social secutiy numbers grows and the currently not available area numbers will have to made available for use.

*Note: If we were able to utilize 245 of the currently unavailable area numbers that are classified as not ready to issue, we would have 753 + 245 = 998 possible 3 digit area numbers. Then the 989,901 possible numbers for each possible area number X 998 area numbers = 987,921,198 possible social security numbers; there is room for almost a billion social security numbers.

* Area numbers - The first three numbers originally represented the state in which a person first applied for a social security card. Numbers started in the northeast and moved westward. This meant that people on the east coast had the lowest numbers and those on the west coast had the highest. Since 1972, the Social Security Administration (SSA) has assigned numbers and issued cards based on the ZIP code in the mailing address provided on the original application form. Since the applicant's mailing address doesn't have to be the same as his residence, his area number doesn't necessarily represent the state in which he resides. For many of us who received our SSNs as infants, the area number indicates the state we were born in. You can find out which area numbers go with each state here.

* Group numbers - These two middle digits, which range from 01 through 99, are simply used to break all the SSNs with the same area number into smaller blocks to make administration easier. (The SSA says that, for administrative reasons, group numbers issued first consist of the odd numbers from 01 through 09, and then even numbers from 10 through 98, within each area number assigned to a state. After all the numbers in group 98 of a specific area have been issued, the even groups 02 through 08 are used, followed by odd groups 11 through 99.)

* Serial numbers - Within each group designation, serial numbers -- the last four digits in an SSN -- run consecutively from 0001 through 9999.

According to the SSA, the numbers are not recycled. Upon an individual's death, the number is removed from the active files and is not reused. Recycling numbers might become an issue someday, but not any time soon -- statisticians say that the nine-digit SSN allows for approximately one billion possible combinations!
