The official search
The registry is run by the Wyoming Secretary of State, Business Division.
- Search page: https://wyobiz.wyo.gov/Business/FilingSearch.aspx (start from https://wyobiz.wyo.gov)
- Cost: Free
- Login: None required
The database covers the business entities registered with the Secretary of State — LLCs, corporations, limited partnerships, statutory trusts, and trade names. Be ready for a human-verification check before the search form loads; the Filing Search does not respond to automated lookups.
There is no separate tool that stamps a name "available" or "taken." You judge availability from the Filing Search results, and the Business Division reviews the name when your filing is submitted. Unusually, Wyoming law makes that homework your legal problem: the Secretary of State's naming guidance states that the online filer is responsible for conducting a search to make sure no entity on record contains the singular or plural form of the name being registered.
A detail record is generally reported to show the legal name, filing ID, entity type, status (such as Active, Delinquent, or Inactive – Administratively Dissolved), date of organization, registered agent and principal office addresses, and filing history. Wyoming is a strong-privacy state, and member or manager ownership information is not part of the public record.
Step by step
- Open WyoBiz and go to the Filing Search. Complete the human-verification check if one appears.
- Search by Filing Name without "LLC." Use the Contains matching option, if offered, rather than Starts With — Contains catches your distinctive words anywhere in an existing name.
- Search the singular and the plural. Wyoming treats singular and plural forms as the same name, so run both: "Outfitter" and "Outfitters," "Advisor" and "Advisors."
- Try spelling and spacing variants. Punctuation, spacing, and capitalization differences do not make a name different in Wyoming, so check the versions a competitor might already hold.
- Remember trade names and trademarks count too. A conflict can come from a registered trade name or a Wyoming-registered trademark or service mark, not only from another LLC or corporation.
- If nothing conflict appears, the name is probably available — but the Business Division's review of your actual filing is the final word.
Wyoming's name rules
The rules are in W.S. 17-29-108 of the Wyoming Limited Liability Company Act, with distinguishability handled under W.S. 17-16-401.
Designator. The name must include one of these: "limited liability company," "LLC," "L.L.C.," "limited company," "LC," "L.C.," "Ltd. liability company," "Ltd. liability co.," or "limited liability co." A low-profit LLC uses "L3C" instead.
Distinguishable — and not deceptively similar to a mark. Your name must be distinguishable upon the records of the Secretary of State from other business names under §17-16-401 — a comparison that reaches corporations, LLCs, limited partnerships, statutory trusts, trade names, fictitious names, and reserved names. Separately, the name may not be the same as, or deceptively similar to, any trademark or service mark registered in Wyoming.
Differences that do not count. Changing only the entity ending, punctuation, spacing, or capitalization does not distinguish a name, and neither does switching a word between singular and plural. The core words have to be genuinely different.
Prohibited implications. The name may not imply the LLC is organized for a purpose outside its articles of organization, and it may not imply it is organized under the Wyoming corporation or nonprofit acts. Words suggesting banking, trust, or education activities may need approval from the relevant state regulator first — confirm with the Business Division before relying on such a word.
Reserving a name. Wyoming allows name reservations under W.S. 17-29-109. The reservation is commonly listed as $60 for 120 days, filed by mail on the Secretary of State's Application for Reservation of Name — check the current form on sos.wyo.gov to confirm the fee before you send it, and do not confuse it with the separate $30 trade name reservation on the fee schedule. A reservation is optional and does not create the LLC.
What the search can't tell you
- A final verdict. The Filing Search shows what is on record; the Business Division decides distinguishability when it reviews your filing.
- Federal rights. A clear Wyoming search says nothing about federal trademarks in the USPTO database or names used in other states.
- Domains. The search says nothing about .com availability.
- Who owns a company. Wyoming's public record does not publish LLC members or managers.
If the name looks available
File Articles of Organization with the Business Division, online through the WyoBiz New Business Entity Wizard at wyobiz.wyo.gov, or on paper by mail or in person.
- Cost: $100 (per the Business Division fee schedule effective July 1, 2026).
Ongoing: the annual report and license tax.
- Fee: $60 minimum — the tax is the greater of $60 or $.0002 per dollar of assets located and employed in Wyoming, so it rises above $60 once Wyoming assets pass $300,000.
- Due date: the first day of your anniversary month each year. Form in January, and the report is due January 1 — the deadline opens the month rather than closing it.
- Late consequences: the fee schedule lists no flat late fee, but an LLC that has not filed within 60 days after the due date is administratively dissolved. Reinstatement for tax costs $100.
FAQ
Is the Wyoming LLC name search free? Yes. The WyoBiz Filing Search is free and needs no account, though it may present a human-verification check.
What endings can a Wyoming LLC name use? "Limited liability company," "LLC," "L.L.C.," "limited company," "LC," "L.C.," "Ltd. liability company," "Ltd. liability co.," or "limited liability co." under W.S. 17-29-108. A low-profit LLC uses "L3C."
Can a Wyoming trademark or trade name block my LLC name? Yes. Section 17-29-108 bars a name that is the same as or deceptively similar to a trademark or service mark registered in Wyoming, and the distinguishability comparison also reaches registered trade names.
How much does it cost to form a Wyoming LLC? The Articles of Organization filing fee is $100.
When is the Wyoming LLC annual report due, and what does it cost? It is due on the first day of your anniversary month each year. The license tax is a $60 minimum, or $.0002 per dollar of Wyoming assets if that is greater. Missing the due date by more than 60 days leads to administrative dissolution.
