Where does the prefix 915 on a SS# originate?

Los Angeles, CA |

I know up to the 800 series of numbers these numbers originate out of their respective states but when does the SS# 915 get used by the Social Security Admin.? Is it issued based on where a person is born or only where it is issued from or applied for?

  1. I have never seen a 915. The prefix is based on the state in which you lived when you were assigned a SS number. This is often the same state in which you were born. A complete list is available at
