Summary table: Finding your Maine entity information

How to search for Maine business entities

Access the Maine business entity search through the Interactive Corporate Services (ICRS) portal to look up any registered business by name or charter number.

Maine's search system offers two primary methods and returns up to 100 matching entities immediately. The portal provides a straightforward interface with two main search fields: one for keyword-based name searches and another for direct charter number lookups.

For name searches, use the "Keyword from name to be searched" field and enter only the distinctive part of your business name. Avoid special characters, punctuation marks, and standard business suffixes like "LLC" or "Corporation" to maximize your search results. 

If you know the specific charter number, use the alternative "Charter number" search field for direct entity lookup. Once you've entered your search criteria, click "Click here to search" to execute your query and view results from Maine's comprehensive database.

What you'll see in search results

Search results display essential information for each matching entity:

• Legal entity name (exact spelling and punctuation)

• Entity type (LLC, Corporation, Partnership, LP, LLP, etc.)

• Charter Number (unique state identifier)

• Status (Active, Inactive, Dissolved, Suspended)

• Filing Date (original registration date)

• Information Summary link for detailed records

Formation date vs. effective date

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

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

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

For most Maine entities, the formation and effective dates are the same, as Maine's standard practice aligns them unless specifically requested otherwise during the filing process.
