What are the SSN prefixes for Louisiana?

Louisiana was assigned the area-number ranges 433-439, 659-665. A Social Security number issued there before 2011 begins with one of these three-digit numbers.

Does an SSN starting with 433 mean the person is from Louisiana?

For cards issued before June 25, 2011, an SSN whose first three digits fall in Louisiana's range was issued in Louisiana, usually based on the mailing address on the application, not necessarily birthplace. Numbers issued after randomization carry no location meaning.
