How to Look Up an LLC in Maine (2026)
To look up an LLC in Maine, search the Secretary of State's Corporate Name Search tool. It runs inside the Interactive Corporate Services (ICRS) system. Search by the business name or by its charter number. The result page shows the entity's current filing details.
The Bureau of Corporations, Elections & Commissions runs that system alongside phone and email support. This guide walks through both search fields and when to call instead. It also covers how to check a name against federal and state trademark records before you commit to it.
Quick Summary
- Search Maine's Corporate Name Search by keyword or by charter number, whichever you have on hand.
- The Bureau of Corporations, Elections & Commissions answers questions the search tool can't, by phone or email.
- Check the USPTO's federal database first, then Maine's own Corporate Name Search. A clean federal search doesn't guarantee a clean state one.
| Search Method | What to Enter | Best For |
|---|---|---|
| By keyword | A partial or full business name in the "Keyword from name to be searched" field | General lookups when you only know the name |
| By charter number | The Secretary of State's assigned charter number in the "Charter Number" field | An exact match when you already have the number |
How Do I Look Up an LLC in Maine
Every Maine business search starts at the same place. Use the Corporate Name Search tool inside the Secretary of State's Interactive Corporate Services system.
1. Search by Keyword
Enter a partial or full business name into the "Keyword from name to be searched" field. This works well when you're not sure of the exact legal name.
2. Search by Charter Number
If you already have the entity's charter number, enter it into the "Charter Number" field instead. That pulls up the record for that entity.
Either search opens an Information Summary page. It lists the charter number, filing type, registered agent information, business address and filing history.
Contact the Bureau of Corporations
Call the Bureau of Corporations, Elections & Commissions at 207-624-7752 when the search tool doesn't answer your question. Customer service phone hours run 10 a.m. to 5 p.m., Monday through Friday. The office itself is staffed 8 a.m. to 5 p.m. those same weekdays.
Email works better for a detailed or document-specific question. Send it to cec.corporations@maine.gov and include the entity's charter number if you have one.
How to Check If a Business Name Is Trademarked in Maine
Clearing a name in Maine's own records doesn't rule out a conflict with a mark registered somewhere else. Run both a federal and a state check before you settle on a name.
1. Search the USPTO's Federal Trademark Database
Start with the USPTO's trademark search system. It covers every mark registered or pending nationwide, so it catches a conflict a Maine-only search would miss entirely.
2. Search Maine's Own Trademark Records
The Corporate Name Search tool used for entity lookups also covers marks and trade names filed directly with Maine. The same division holds both kinds of records. The Secretary of State may also refuse to file a name that's too close to one already on record. That includes registered marks, unless the mark's owner is the one filing [1].
3. Talk to a Trademark Attorney for Anything Close
Neither database catches common-law trademark rights built through actual use rather than registration. If your search turns up something close but not identical, talk to a trademark attorney. They can weigh the real risk before you spend money building a brand around the name.
Reasons to Run a Maine LLC Search
A search settles more than name availability. It also helps you start an LLC in Maine without hitting a naming conflict after you've already filed. Here's what else a search settles:
- Confirm the company's on file: verify a business you're dealing with is actually registered in Maine before you sign anything.
- See who's on file as registered agent: that's handy if you're comparing Maine's best registered agent services or need to reach the current agent directly.
- Check for naming conflicts: catch a name that's already taken before you draft paperwork around it.
- Support due diligence: check a business's filing record before buying it or entering a partnership with it.
The LLC you're checking might be based outside Maine. Our guide to looking up an LLC covers that same process, state by state.
FAQs
Can I Reserve an LLC Name in Maine Before I File?
Yes. File a Name Reservation Request with the Secretary of State to hold your chosen name while you finish your formation paperwork.
What Should I Do If My Name Is Already Trademarked?
If your name is already trademarked, modifying it is usually the simpler path. Bring in a trademark attorney only if you're set on keeping the name and want a second opinion before you commit to it.
How Do I Change an LLC's Name After It's Registered?
You change an LLC's name after it's registered through the Bureau of Corporations, Elections & Commissions. Call or email them directly for the current filing requirements and the form you'll need.
