Yes. Originally, the first three digits are assigned by the geographical region in which the person was residing at the time he/she obtained a number. Generally, numbers were assigned beginning in the northeast and moving westward. So people on the east coast have the lowest numbers and those on the west coast have the highest numbers. The remaining six digits in the number are more or less randomly assigned and were organized to facilitate the early manual bookkeeping operations associated with the creation of Social Security in the 1930s.

Beginning on June 25, 2011, the SSA implemented a new assignment methodology for Social Security Numbers. The project is a forward-looking initiative of the Social Security Administration (SSA) to help protect the integrity of the SSN by establishing a new randomized assignment methodology. SSN Randomization will also extend the longevity of the nine-digit SSN nationwide.
