Social Security Number Issued Year Esitmation

The Social Security Number issued year estimation is based on birth year on Death Master Fil(DMF). We collect all birth year for the SSN group from DMF file, and get the rough range for SSN issued year.

The SSN number is used from 1936, so the earliest year for all SSN group is 1936, and the highest group year is from the highest year number for all birth year in death reports of the SSN group.

And SSN number radomization is from June 25, 2011, and thus SSN number issued after the date is random, and can't represent the area/State information any more.

So SSN issued year estimation is only for your reference, and we don't guarantee the correctness for this estimation.

Use those data for your owen risk.
