Name Your Wyoming LLC — Step 1 of 8

Your name needs to do two things: carry the right LLC designator and be distinguishable from every other Wyoming entity. Wyoming's distinguishability test is stricter than most — it even treats singular and plural as the same. Here's how the rules work, plus a checker to pressure-test your name before you file.

Quick Answer

A Wyoming LLC name must include a designator — "LLC," "L.L.C.," "LC," "L.C.," "Limited Liability Company," or "Limited Company" — and be distinguishable from existing Wyoming entities. It can't use corporate words (Inc., Corp.) or imply a bank, insurer, or government agency. Search free at wyobiz.wyo.gov, and optionally reserve a name for $60 (120 days).

Wyoming's LLC Naming Rules

Wyoming's naming rules (Wyo. Stat. §17-29-108) come down to three things: the right designator, distinguishability, and avoiding misleading words. Get all three right and your Articles of Organization sail through.

  • Include a designator: "Limited Liability Company," "Limited Company," "LLC," "L.L.C.," "LC," or "L.C." You may abbreviate "Limited" to "Ltd." and "Company" to "Co."
  • Be distinguishable from every existing Wyoming entity name on file with the Secretary of State.
  • Don't mislead the public — no corporate designators (Inc., Corp.) and nothing implying a bank, insurer, or government agency.

Restricted & prohibited words

Your name can't suggest a different entity type or a regulated/government activity. These typically require approval or are off-limits:

Inc.Corp.IncorporatedbanktrustinsuranceFBITreasuryState Department

Wyoming Name Compliance Checker

Type your proposed name to instantly check the designator and scan for restricted words. Then run the official WyoBiz search to confirm it's available:

Name Compliance Checker
Checks designator + restricted words (not availability)

This checks formatting and restricted words only. It does NOT confirm the name is available — always run the official WyoBiz business search before filing. Not legal advice.

Wyoming's distinguishability test is strictThe state ignores spaces, punctuation, capitalization, designators, and the words "The," "A," "And," and "&." Crucially, Wyoming also treats singular and plural as the same — so if "Mountain Peak LLC" exists, you can't register "Mountain Peaks LLC." You need a genuinely different word, not a tweak.

  • Search WyoBiz: use the Secretary of State's free Business Search and try the core words without the designator, using the "Contains" filter.
  • Check trademarks: run a quick USPTO search — a name can be free in Wyoming but federally trademarked.
  • Reserve if needed ($60): not filing right away? Hold your name for 120 days by mailing an Application for Reservation of Name. Skip it if you're filing now.
  • Grab the domain and social handles while you're at it, so your brand is consistent.
Search Names on WyoBiz
Ahmad Adil's Take: The plural-vs-singular rule trips people up in Wyoming more than anywhere else, so don't assume adding an "s" frees up a taken name — it won't. Pick two or three options, search the core words with the "Contains" filter, and check the .com and trademark database before you commit. Most founders filing right away can skip the $60 reservation entirely — it's a mail-in form that takes up to 15 business days, so it only makes sense if you genuinely need to lock a name weeks ahead.

Frequently Asked Questions

Wyoming LLC Name — FAQ

What words must a Wyoming LLC name include?
Your name must include a designator: "Limited Liability Company," "Limited Company," "LLC," "L.L.C.," "LC," or "L.C." You can abbreviate "Limited" to "Ltd." and "Company" to "Co." — "LLC" is the most common ending.
How do I check if my Wyoming LLC name is available?
Use the Wyoming Secretary of State's free Business Search at wyobiz.wyo.gov. Search the core words of your name (without the designator) and use the "Contains" filter to catch similar names. The state has final say until your filing is approved.
What words are restricted in a Wyoming LLC name?
You can't use corporate designators like "Inc." or "Corp." in an LLC name, and words implying a bank, trust, insurance company, or government agency (such as "FBI" or "Treasury") are restricted or require approval. These misidentify the entity type, so the state will reject the filing.
How much does it cost to reserve a name in Wyoming?
A name reservation costs $60 and holds your name for 120 days. You file an Application for Reservation of Name by mail (it can't be emailed, and processing takes up to 15 business days). It's optional — if you're filing your Articles right away, you can skip it.
Does Wyoming treat singular and plural names as different?
No — and this is unusual. Wyoming treats singular and plural as equivalent, so you can't register "Summit Ventures LLC" if "Summit Venture LLC" already exists. It also ignores punctuation, spacing, capitalization, designators, and "The/A/And/&." You need a genuinely different word.
Can I use a trade name (DBA) in Wyoming?
Yes. If you want to operate under a different brand than your LLC's legal name, you can register a trade name (DBA) with the Secretary of State (a $100 registration, valid for a 10-year term). Your LLC remains the legal owner; the trade name is just a public-facing name it can use.
Does a name search guarantee trademark protection?
No. Clearing the Wyoming name database only means no other Wyoming entity has that name. A business elsewhere could still hold a federal trademark. Always run a quick USPTO trademark search before committing to branding, a logo, or a domain.
