Social Security Number Prefixes by State
Before June 25, 2011, the first three digits of a Social Security number (the area number) were assigned by the state or territory on the mailing address of the application.
Since 2011 randomization, new SSNs have no geographic meaning. Never enter a full SSN on any third-party website.

SSN Prefix FAQs
Do the first three digits of an SSN show the state today?
Only as a historical clue for numbers issued before June 25, 2011. Numbers issued after randomization do not have geographic meaning.
Does an SSN prefix prove where a person was born?
No. A historical area number was generally tied to the mailing address used for the original application, not necessarily birthplace or current residence.
What is an SSN area number?
The area number is the first three digits of a Social Security number. This page lists historical area-number ranges by state and territory.
Can I identify someone from an SSN prefix?
No. A prefix does not identify a person, confirm ownership, or show a current address. Do not share a full Social Security number with this directory.
