Need to verify a contractor, check if a business name is available, or look up a company before signing a contract? Maine makes this easy through a free public database.
Here’s the direct answer: search Maine businesses at the Maine Secretary of State’s website using their online business entity search tool. It’s free, requires no account, and returns results in seconds.
Step-by-Step: How to Search
- Go to the Maine Secretary of State’s online business search portal.
- Choose how you want to search — by business name, registered agent name, or entity number.
- Enter your search term. You don’t need the exact full name — partial searches work.
- Click “Search.”
- A list of matching businesses will appear. Click on any result to view full details.
Tip: If you’re searching a common name, add a keyword to narrow results (e.g., “Portland Plumbing” instead of just “Portland”).
What Information You Can Find
| Field | What It Tells You |
| Entity Name | Official registered business name |
| Entity Type | LLC, Corporation, Partnership, etc. |
| Status | Active, Dissolved, Revoked, etc. |
| Date of Formation | When the business was registered |
| Registered Agent | The person/entity authorized to receive legal documents |
| Registered Office Address | Official business address on file |
| Annual Report Status | Whether they’re up to date with state filings |
This information is public record — anyone can view it at any time.
Why People Use This Search
Verifying a contractor or vendor. Before paying a business, you can confirm they’re legally registered and in good standing with the state.
Checking name availability. If you’re starting a business, this tool lets you see if your desired business name is already taken. Keep in mind that checking here is a starting point — you’d still need to confirm no trademark conflicts.
Due diligence for a business deal. Investors, buyers, and partners often run a business search as a first step before any deeper review.
Finding a registered agent. If you need to serve legal documents to a business, the registered agent on file is the official contact.
How to Register a New Business in Maine
If your name search comes back clear and you’re ready to form a business, Maine handles registrations through the same Secretary of State portal.

| Corporation | $145 | 5–10 business days |
| Nonprofit | $40 | 5–10 business days |
| Expedited (any type) | Add 100 | 1–2 business days |
Online filings process faster than paper submissions.
What If the Business Doesn’t Show Up?
Not all Maine businesses appear in this database. Here’s why:
Sole proprietors operating under their own legal name are generally not required to register with the state and won’t appear in this system.
DBA (“doing business as”) registrations in Maine are filed at the county level, not the state level — so a business operating under a trade name may not show up here even if it’s legitimate.
Federal entities and nonprofits may be registered differently. Federally chartered entities or out-of-state businesses operating in Maine may have a different filing structure.
Out-of-state companies that do business in Maine but aren’t formally registered here also won’t appear.
If a business is missing from the database, it doesn’t automatically mean it’s fraudulent — but it’s worth asking them directly about their registration status.
The Maine business search tool is one of the more straightforward state databases out there. It takes under a minute to use and gives you reliable, up-to-date information straight from the source.
