Plain-language answer

What Massachusetts prefixes mean

Before June 25, 2011, an older SSN beginning with an area number in the ranges below was associated with Massachusetts in the historical assignment record, usually through the mailing address on the original application.

For example, an old number beginning with 010 may fit this historical Massachusetts area-number record. This does not identify a person and does not show where the person lives now.

Why newer numbers are different

Randomization ended the geographic connection for new numbers. The first three digits of a newer SSN cannot reliably tell you a state or territory.
