Security company licensing in Massachusetts

Massachusetts Department of State Police, Certification Unit licenses security companies here, but we do not yet carry its roster, so we cannot tell you who is on it.

The State Police publish an 'Active Watchguards' file listing 244 licensed agencies with business name, address, phone, named licensee, licence number and both effective and expiry dates. The download link carries a new dated address each time the list is refreshed, so it has to be found from the certification unit page rather than remembered.

Until then, verify a company with the regulator directly, and treat any license number a company gives you as a claim we have not checked.

There is a second license, and in Massachusetts it may be the only one that exists: the guard’s own.
