What are the SSN prefixes for Arizona?

Arizona was assigned the area-number ranges 526-527, 600-601, 764-765. A Social Security number issued there before 2011 begins with one of these three-digit numbers.

Does an SSN starting with 526 mean the person is from Arizona?

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