The Numerical Index File, or Numident, is the main database that keeps the information regarding Social Security Numbers. One record exists for each Social Security Number issued and is updated when each Numident receives new data on the individual.

The first three digits are called the area number, and they represent the state or territory that the Social Security number originates from.

The next two digits designate the group number, and that number goes from 01 to 99 as new groups get assigned. The last four digits portray the serial number. There are a billion number combinations possible because Social Security numbers are nine digits.Learn more about Social Services
