The official search
The registry is run by the New Mexico Secretary of State, Business Services Division, through its online system called SOS Enterprise.
- Search page: https://enterprise.sos.nm.gov/search/business
- Cost: Free
- Login: None required to search (filing requires an Enterprise account)
The database covers LLCs, corporations, nonprofit corporations, limited partnerships, and other entities filed with the Secretary of State, both New Mexico-formed and foreign entities authorized here. Older links to a portal.sos.state.nm.us search no longer work — Enterprise replaced that system, so update any bookmark you find in an older guide.
A name search needs at least two letters or numbers. A results list shows the entity name, Business ID, entity type and subtype, formation date, and legal status. A detail record adds the registered agent's name and address, the principal address, the filing history, and any alternate business name on file. One thing it will never show for an LLC is the owners: New Mexico's Articles of Organization do not ask for member or manager names, so ownership stays off the public record entirely. All business filings are now online only through Enterprise — paper filings are no longer accepted.
Step by step
- Open the SOS Enterprise Business Search and type your name — without "LLC" — into the basic search box, or search by Business ID if you already have one for a specific company.
- Open Advanced search. This is where the useful controls are: match modes, plus filters for entity type, status, and registration date.
- Run a Contains search on the most distinctive word in your name. This finds every record with that word anywhere in its name — the widest useful net.
- Run a Starts With search on the opening words of your name, to catch names that begin the same way.
- Run the Name Availability mode on your full proposed name. This is the mode designed for new filings — but read its result carefully: the Secretary of State states that the business search "is only a preliminary search and not intended to serve as a formal name availability search." The formal decision is made when your filing or reservation is reviewed.
- Weigh the matches, don't just count them. Your name must be distinguishable, not merely different by an ending. If a close match is on file — an LLC, a limited partnership, a corporation, or even a reserved name — assume it can block you until the Secretary of State says otherwise.
New Mexico's name rules
The rules are in NMSA 1978 § 53-19-3 of the Limited Liability Company Act.
Designator. The name must contain "limited liability company" or "limited company," or the abbreviation "L.L.C.," "LLC," "L.C.," or "LC." Inside the designator, "limited" may be shortened to "Ltd." and "company" to "Co." If you plan to do business in New Mexico under a different name, that name must also be stated in your Articles of Organization and must meet the same designator rule.
Distinguishable. The name must be distinguishable from the name of:
- Any LLC, limited partnership, or corporation existing under New Mexico law
- Any foreign LLC or corporation authorized to transact business in New Mexico
- Any name reserved under § 53-19-4
One narrow exception. The distinguishability rule does not apply if you file a certified copy of a final court decree establishing your prior right to use the name in New Mexico. That is a courtroom route, not a paperwork shortcut.
Restricted words. Section 53-19-3 itself does not publish a list of banned words, unlike many states. Be careful anyway with words implying a regulated business — banking, insurance, or trust activities are licensed under other New Mexico laws, and a name suggesting you are in one of those businesses without a license can create problems beyond the Secretary of State.
Reserving a name. New Mexico allows name reservations under § 53-19-4: $20 for 120 days, filed with the Secretary of State through Enterprise. The catch: the reservation cannot be renewed. When the 120 days end, the name goes back into the pool, so reserve only when you are genuinely close to filing. A reservation is optional — it does not form an LLC.
What the search can't tell you
- A formal availability verdict. Even the Name Availability mode is, in the Secretary of State's own words, a preliminary search. Approval comes only when your filing or reservation is reviewed.
- Whether a business is really operating. Because New Mexico LLCs file no annual report, a company can show "Active" for years after it has effectively been abandoned. Status here is weaker evidence than in states with yearly filings.
- Who owns an LLC. Member and manager names are not collected on the Articles and never appear in the record.
- Trademarks, domains, and DBAs. The search says nothing about federal trademark rights or .com availability. New Mexico also has no separate state DBA registration to check — a different business name an LLC uses is stated in its Articles instead.
If the name looks available
File Articles of Organization with the Secretary of State, online through SOS Enterprise at enterprise.sos.nm.gov. You will need an Enterprise account to file.
- Cost: $50. That is the state filing fee set by NMSA 1978 § 53-19-63.
- What it needs: your LLC's name (plus any different name you will transact business under), your registered agent and registered office in New Mexico, and a dissolution date only if you want one. No member or manager names are required.
Ongoing: there is no annual report.
- New Mexico LLCs file no annual or biennial report with the Secretary of State, and pay no annual report fee. The Limited Liability Company Act simply contains no report requirement for LLCs. Do not confuse this with corporations, which do file biennial reports here.
- Ignore the "triennial report" rumor. Some websites claim a 2024 law added an LLC report every three years. The bill behind that claim (2023 HB 281) was never passed — the Legislature's own record shows it died in 2023. No such report exists.
- Your one real ongoing duty is keeping a registered agent and registered office in New Mexico on file, and filing a statement of change if either changes. That is the requirement that actually ends New Mexico LLCs: under § 53-19-66.1, going without an agent or office — or failing to file the change statement — is a ground for administrative revocation. With no annual report, nobody sends you a yearly reminder, so keep your agent's details current yourself.
FAQ
Is the New Mexico LLC name search free? Yes. The SOS Enterprise Business Search is free and requires no login. You need an account only when you file.
What does the "Name Availability" search mode do? It tests your proposed name against the records for a new filing. It is a helpful first check, but the Secretary of State calls the business search preliminary — it is not a formal availability ruling. The decision is made when your filing or reservation is reviewed.
How much does it cost to form a New Mexico LLC? The Articles of Organization filing fee is $50.
Does a New Mexico LLC have to file an annual report? No. New Mexico LLCs have no annual or biennial report and no annual report fee. Your ongoing duty is to keep a registered agent and registered office on file. Claims online about a new triennial report are based on a bill that never became law.
Can I reserve an LLC name in New Mexico? Yes. A reservation costs $20 and holds the name for 120 days — and it cannot be renewed, so file your Articles before it expires.
