Massachusetts business search
Look up a Massachusetts company by name or entity number and get the record live: name, entity type, status, formation date and address. The shape of the number is checked in your browser first.
The same lookup with curl

What the Massachusetts data holds
The data is the Corporations Division's public-record extract (19 Oct 2026; refreshed, with its change events, only when the Division supplies a newer extract), a file the Division supplied. It is not an official register extract, and the Secretary of the Commonwealth does not endorse these records. It covers business, professional, benefit and non-profit corporations, limited liability companies, limited partnerships, registered limited liability partnerships, co-operatives and the Chapter 180 and special-statute corporations, domestic and foreign.
Every status is served: active, dissolved, revoked, withdrawn, and inactive (closed, no reason given), so a dissolved company answers instead of a 404. A closed entity carries its closing date as dissolution_date, except inactive. The extract is a snapshot, refreshed only when the Division supplies a newer one.
Sources as at 6 Nov 2026.
The Massachusetts number: MA- plus the register number
A Massachusetts company number is MA- and the entity number, usually digits and sometimes letters: MA-042456637 is State Street Corporation (Boston, organised 16 Oct 1969, active). Only the shape is verified, there is no check digit. A name works as well: type it and pick the match.
The address is the primary address.
What is not served
Trade names (foreign DBAs), voluntary associations and trusts, corporations sole and confidential entities are never served. There are no officers, directors or resident agents.
