New Mexico Secretary of State business search — LLC name check, trademark & domain lookup
New Mexico is a favorite for privacy-minded founders: a $50 LLC with no annual report and no requirement to list members publicly. That anonymity has a side effect for name searches — the registry tells you a name is taken but often nothing about who holds it, so a conflict can't be negotiated around.

- Type the exact name, suffix included. The checker runs it against the New Mexico registry, the federal trademark register and domain registrars in one pass.
- Read the close matches, not just the verdict. New Mexico refuses names that aren't distinguishable — a near-miss on the list is the one that will block you.
- Reserve or file while it's clear. New Mexico will hold it for 120 days for $20. Confirm at the official New Mexico Secretary of State search first.
New Mexico naming rules: what the New Mexico Secretary of State will and won't accept
The rule that matters most in New Mexico is distinguishable upon the records of the Secretary of State. In practice that means a name that differs from an existing one only by punctuation, spacing, capitalization or the entity suffix will be refused. An LLC name must end in LLC, L.L.C., Limited Liability Company and Limited Company; a corporation uses Corporation, Corp., Incorporated and Inc., among others.
Some words need permission first. In New Mexico that list includes Bank, Trust, Insurance, Engineer and Cooperative — using one implies a regulated activity and the filing will be held until the relevant regulator consents.
On cost: forming an LLC costs $50, a corporation $100 and a name reservation is $20 and holds the name for 120 days. Online filings are usually immediate to 1 business day.
The ongoing obligation: Corporations file a biennial report ($25); New Mexico LLCs file NO annual report. Skip it and the state eventually dissolves the entity, releasing the name back into the pool.

What makes a name available in New Mexico?
- It must be distinguishable from names already on the New Mexico registry — usually more than a difference in punctuation, spacing, or an entity suffix.
- Only active registrations block a name. A dissolved or revoked entity with the same name typically doesn't stop you — though a recently inactive one can carry a reinstatement risk worth knowing about (our checker flags exactly that case).
- Entity suffixes are required, not decorative. An LLC's legal name must carry an LLC designator; a corporation needs Inc., Corp., or an equivalent accepted in New Mexico.
- Registry clearance is not trademark clearance. The New Mexico Secretary of State checks its own records only — it will register a name that infringes a federal trademark. Check both.

Confirming the result on the New Mexico Secretary of State's site
Treat the checker as the fast filter and the state's own search as the final word. Once a name comes back clear here, open the New Mexico entity search and type the name the way it will appear on the formation document — designator and all. Read down the list of matches rather than stopping at "no exact match": look at each record's status (only active ones block you) and at how close the spelling is, because New Mexico rejects near-duplicates as well as duplicates. If the name is still clear, reserve it or file the same day; registrations are first-come, first-served and the registry moves daily.
Frequently asked questions
- Are there words I can't use in a New Mexico business name?
- Words that imply a regulated business need consent first. In New Mexico that includes Bank, Trust, Insurance, Engineer and Cooperative. Names that suggest a government agency are refused outright.
- How many new businesses start in New Mexico each year?
- The Census Bureau counted 44,099 business applications in the twelve months to August 2026, +20.3% on the year before. Not every application becomes a registered entity, but each one is a name someone intends to use.
- Does a New Mexico registration protect my name in other states?
- No. It protects the name inside New Mexico's registry only. Nationwide protection comes from a federal trademark, which is why the checker runs the USPTO search alongside the New Mexico lookup.
- What does a New Mexico LLC name have to end with?
- One of the state's accepted designators — LLC, L.L.C., Limited Liability Company and Limited Company. The checker searches the name with and without the suffix, because the suffix alone never makes a name distinguishable.
- Can I reserve a business name in New Mexico before I file?
- Yes. The New Mexico Secretary of State charges $20 to reserve a name for 120 days. A reserved name shows as taken to everyone else's search.
- How much does it cost to register a business name in New Mexico?
- The name itself is free to search. Filing the entity is what costs money: $50 for an LLC and $100 for a corporation, then corporations file a biennial report ($25); new mexico llcs file no annual report.
