Maine LLC Name Search

How to search for LLC names in Maine

Searching for an available LLC name in Maine is a required first step before submitting your Certificate of Formation to the Maine Secretary of State. The online business entity search database lets you check whether a proposed name is already in use by an active or recently dissolved entity. The search results show registered businesses, reserved names, and trade name registrations — all of which can block your filing if your name is not sufficiently distinguishable. Finding no exact match does not guarantee your name will be approved; the Secretary of State reviews distinguishability at the time of filing and may reject names that are confusingly similar to existing registrations. Running this search early saves filing fees and delays, especially if you plan to build a brand or website around your chosen name.

2. 2. Click the 'Search for a Business Entity' link or select the entity search option from the online services menu.
3. 3. Enter your proposed LLC name or a keyword in the name search field; you can search by the full name or partial terms to surface similar names.
4. 4. Review all results carefully, including active entities, inactive entities, reserved names, and trade name registrations that could conflict with your proposed name.
5. 5. If no conflicting names appear, note the search results as evidence of availability before proceeding to file your Certificate of Formation with the required $175 filing fee.

Maine LLC naming rules

• Your LLC name must contain the words 'Limited Liability Company', the abbreviation 'LLC', or 'L.L.C.' — Maine law requires one of these designators to identify the entity type.
• The name must be distinguishable upon the records of the Maine Secretary of State from the names of all other registered or reserved business entities in Maine.
• Your name cannot imply that the LLC is organized for a purpose other than what is permitted for an LLC, or suggest government affiliation with agencies such as the U.S. government, Maine state government, or any county or municipality.
• Words such as 'Bank', 'Banking', 'Trust', 'Insurance', 'Surety', and similar financial or regulated terms require prior written approval from the applicable Maine regulatory agency before inclusion in an LLC name.
• Professional designators like 'Attorney', 'Lawyer', 'Doctor', 'Engineer', 'Architect', or similar terms may require licensing board approval and are restricted to entities composed of licensed professionals.
• The name cannot contain obscene language or terms that are misleading to the public about the nature or purpose of the business.
• The name cannot be identical or deceptively similar to a name already on file — minor variations such as adding punctuation, an article like 'The', or a common plural do not make a name sufficiently distinguishable.
• If your LLC will use a name other than its legal registered name for doing business, you must file a trade name registration separately with the Maine Secretary of State.

Restricted words in Maine LLC names

The following words require special approval from a state agency before you can use them in your Maine LLC name:

• Bank / Banking / Banker — requires Maine Bureau of Financial Institutions approval
• Trust / Trust Company — requires regulatory approval from Maine financial authorities
• Insurance / Insurer / Assurance — requires Maine Bureau of Insurance approval
• University / College — requires approval from the Maine Department of Education or appropriate accrediting body
• Attorney / Lawyer — restricted to licensed legal professionals and may require bar association review
• Engineer / Engineering — restricted use requiring Maine Board of Licensure for Professional Engineers review
• Doctor / Medical / Clinic — may require Maine Board of Licensure in Medicine or Department of Health approval
• Federal / National / United States / U.S. — terms implying federal government affiliation are prohibited without proper authorization

How to reserve an LLC name in Maine

Maine allows you to reserve an LLC name before filing by submitting a Name Reservation application to the Secretary of State's office with a $20 fee. A reservation holds your chosen name exclusively for 120 days, preventing other businesses from registering it while you prepare your formation documents. Name reservations are not renewable; if you need more time beyond 120 days, you must submit a new reservation application with another $20 fee after the original period expires.

Tips for choosing an LLC name that passes in Maine

• Search for both the exact spelling and common misspellings or phonetic variations of your name, since the Secretary of State may flag names that sound similar even if spelled differently.
• After confirming Maine availability, run a search on the USPTO trademark database at tmsearch.uspto.gov to ensure your name does not infringe on a federally registered trademark.
• Check domain name availability for your business name at the same time — securing a matching .com domain early prevents a competitor from taking your web identity.
• Avoid names that are overly geographic, such as 'Maine Coast Consulting LLC', unless your business truly operates in that region, as geographic descriptors can limit your brand if you expand beyond the state.
• Choose a name with long-term flexibility in mind — names tied too closely to a single product, service, or trend may require a costly rebrand if your business pivots or grows.
• If the Secretary of State's database shows a conflicting name from a dissolved or inactive entity, contact the office directly to confirm whether that name is truly blocked, as inactive entities sometimes no longer hold name rights.
