What are the SSN prefixes for Texas?

Texas was assigned the area-number ranges 449-467, 627-645. A Social Security number issued there before 2011 begins with one of these three-digit numbers.

Does an SSN starting with 449 mean the person is from Texas?

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