Summary table: Finding your Massachusetts entity information

How to search for Massachusetts business entities

Access the Massachusetts business entity search to look up any registered business by entity name, individual name, identification number, or filing number.

The search returns results immediately with all entity details visible on the summary page. Navigate to the Massachusetts Corporations Division Business Entity Search portal and select your preferred search method. 

You have four options: 

• Entity Name (for business name searches)

• Individual Name (to find businesses associated with a person)

• Identification Number (for direct entity lookup)

• Filing Number (for specific document searches).

For entity name searches, enter your business name in the search field. Partial matches work well; for example, searching "Boston Tech" will return "Boston Tech Solutions LLC" and similar entities. However, for precise results, we advise that you enter your entity name exactly as registered.

Once you enter your search criteria, click "Search" to view results. The system displays a comprehensive list showing entity names, types, status, and identification numbers. 

Click on any entity name to access the complete business profile with formation date, registered agent information, principal office address, and complete filing history.

Formation date vs. effective date

Massachusetts allows businesses to specify a future effective date when filing, creating two different dates:

• Formation date (file date): When the Secretary of the Commonwealth processed your paperwork

• Effective date: When your entity officially began operations (if you specified a later date)

For most Massachusetts entities, the formation and effective dates are the same, as few businesses request delayed effective dates for their entity formation.
