Massachusetts LLC Name Search

How to search for LLC names in Massachusetts

Searching for an available LLC name in Massachusetts is a required step before submitting your Certificate of Organization to the Secretary of the Commonwealth. The online database displays all active and recently dissolved business entities registered in the state, allowing you to check whether your desired name conflicts with an existing one. Running a search costs nothing and takes only a few minutes. Keep in mind that finding no exact match does not guarantee your name will be approved — the Secretary of the Commonwealth applies a "distinguishable on the record" standard, meaning names that are confusingly similar to existing entities can still be rejected. A clean search result is a strong signal of availability, not a legal reservation or approval of the name.

Step-by-step: using the Massachusetts Secretary of the Commonwealth, Corporations Division name search

1. 1. Navigate to the Massachusetts Secretary of the Commonwealth business entity search at https://corp.sec.state.ma.us/CorpWeb/CorpSearch/CorpSearch.aspx.
2. 2. In the 'Search For' field, enter your desired LLC name or a keyword portion of it, then set the entity type filter to 'LLC' or leave it as 'All' to see conflicts across all entity types.
3. 3. Review the search results list for exact matches and names that are phonetically similar, have common abbreviations, or differ only by punctuation, spacing, or the LLC designator.
4. 4. Click on any similar-sounding entity name in the results to view its full record, including its status (active, dissolved, revoked) — dissolved entities may still block your name under Massachusetts rules.
5. 5. If no conflicting names appear after checking variations and similar spellings, your name is likely available; proceed to file your Certificate of Organization or reserve the name by submitting Form RN with the required fee.

Massachusetts LLC naming rules

• The name must contain the words 'Limited Liability Company,' or the abbreviation 'LLC' or 'L.L.C.' — these designators signal the entity type and are required under Massachusetts General Laws Chapter 156C.
• The name must be distinguishable on the record from any other business entity already registered or reserved with the Massachusetts Secretary of the Commonwealth, including corporations, LLPs, and LLCs.
• The name may not contain language that implies the LLC is a government agency, municipality, or state instrumentality — words like 'Department,' 'Bureau,' 'Division,' or 'Federal' that suggest official government status are prohibited.
• Restricted professional terms such as 'Bank,' 'Banking,' 'Trust,' 'Insurance,' 'Cooperative,' 'Credit Union,' or 'Savings' require prior written approval from the applicable Massachusetts regulatory authority before the Secretary of the Commonwealth will accept the filing.
• Terms suggesting a licensed profession — such as 'Attorney,' 'Doctor,' 'Engineer,' or 'Architect' — may require proof that all members hold the relevant professional licenses under Massachusetts law.
• The name may not include obscene language, language that is likely to mislead the public about the nature or purpose of the business, or words that could constitute fraud.
• Numbers and abbreviations are permitted and treated as their spelled-out equivalents during distinguishability review — '1st' and 'First,' or 'Co.' and 'Company,' are treated as identical.
• Massachusetts does not require the designator to appear at the end of the name, but it must appear somewhere in the full legal name as filed on the Certificate of Organization.

Restricted words in Massachusetts LLC names

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

• Insurance / Insurer / Assurance — requires approval from the Massachusetts Division of Insurance
• Trust / Trustee — requires approval from the Massachusetts Division of Banks or relevant authority
• Credit Union — requires approval from the Massachusetts Division of Banks
• University / College / Academy — may require authorization from the Massachusetts Department of Higher Education
• Engineer / Engineering — may require confirmation that licensed professional engineers are involved, per Massachusetts Board of Registration of Professional Engineers
• Attorney / Law / Legal Services — may trigger professional services review if the entity will practice law in Massachusetts
• Cooperative / Co-op — requires evidence of cooperative structure and may require additional regulatory clearance

How to reserve an LLC name in Massachusetts

Massachusetts allows prospective LLC owners to reserve a business name before filing by submitting Form RN (Reservation of Name) to the Secretary of the Commonwealth along with a $30 filing fee. A reservation holds the name exclusively for 60 days and is not renewable — if you need more time, you must file a new reservation after the first one expires, paying the fee again. Reservations can be submitted by mail or in person at the Corporations Division office in Boston.

Tips for choosing an LLC name that passes in Massachusetts

• Search not only your exact desired name but also common misspellings, phonetic equivalents, and versions with and without spaces or punctuation — the Secretary applies a broad distinguishability standard.
• After confirming state-level availability, search the USPTO Trademark Electronic Search System (TESS) at tmsearch.uspto.gov to ensure no federally registered trademark conflicts with your chosen name.
• Check domain name availability simultaneously using a registrar such as Namecheap or GoDaddy — securing a matching .com domain the same day you file prevents others from claiming it.
• Avoid names that are geographically descriptive of a region you do not exclusively serve (e.g., 'Boston Metro LLC') as these can create confusion and may be harder to protect as trademarks later.
• Choose a name broad enough to accommodate future business expansion — a name tied too tightly to a single product or city can limit your brand as the business grows beyond its original scope.
• Run a Massachusetts-specific web and social media search on your chosen name to verify no unregistered business in the state already operates under it, which could create common-law trademark conflicts even if the name is technically available on the SOS database.
