You can look up any Wyoming LLC through the Secretary of State's Business Entity Search at wyobiz.wyo.gov. Type in the company's name or its filing ID, and the tool shows whether that name is taken and whether an existing LLC is in good standing.

A Wyoming LLC search takes just a few minutes online. This guide walks through the exact steps, shows you where to check for a trademark conflict and lists the office contact you'd use if the online tool doesn't answer your question.

Quick Summary

How to Search for an LLC Name in Wyoming

To search for an LLC name in Wyoming, open the Business Entity Search page. It holds the filing record for every company on file with the state, current and dissolved.

Here's how to run a search:

1. Go to the Business Entity Search page.
2. Choose whether to search by Filing Name or Filing ID.
3. Enter the name and pick "Starts With" or "Contains," depending on how much of the name you know.
4. Click Search, then select the entity you want from the results list.
5. Open the record to see its filing status.

Not ready to file yet? Wyoming lets you hold a name for 120 days by mail for $60 under Wyoming Statute 17-29-109 [1].

Use the Wyoming Business Name Search

The search page gives you two ways to look up a filing, and each one fits a different situation depending on what information you already have on hand.

a. Name Search

Use this when you know the company's name but not its filing number. Type in as much of the name as you have, choose "Starts With" for an exact beginning or "Contains" for a partial match anywhere in the name, then run the search. Most people use this method to check whether a name is free before filing to start an LLC in Wyoming.

b. Filing ID Search

Use this if you already have the entity's Filing ID, formatted like 2000-000123456. It's a faster route to a specific record when you already have the number from a document or a prior search.

The portal's own search tips are worth reading before you start. They explain what a "good standing" result means: the entity's required paperwork and fees are current. Try both a name search and a Filing ID search if your first attempt doesn't turn up the record you expect.

How to Check If a Business Name Is Trademarked in Wyoming

Wyoming's Secretary of State registers state-level trademarks separately from LLC names, so a clean business entity search doesn't guarantee your name or logo is free of trademark conflicts. Checking both layers protects you from a name dispute after you've already filed. Closing that gap takes three separate checks, one federal and two at the state level.

• Search the federal trademark database. The USPTO Trademark Search System covers marks registered nationwide, which matters if you plan to operate or sell outside Wyoming.
• Check Wyoming's own trademark records. The Secretary of State's Trademark Registration page links to a searchable historical collection of state-registered marks. For a definitive answer on whether a specific mark is currently active, contact the Business Division directly at 307-777-7311.
• Compare close matches carefully. A name doesn't have to be identical to cause a conflict. Wyoming law blocks registration of a mark that's "deceptively similar" to one already on file [2].

Registering an LLC and registering a trademark are two separate filings with two separate fees. Forming the LLC only protects the entity's legal name in Wyoming. A state trademark registration currently costs $100 and protects a specific mark, name or logo used in commerce.

Reasons to Perform a Search

A search pays off for a few concrete reasons, from confirming legal compliance to avoiding a rejected filing down the road.

• Legal compliance: Litigation, contract disputes and regulatory filings often require proof that an LLC exists and is in good standing.
• Brand protection: Confirming a name is free before you file keeps you from building a brand around a name someone else already owns.
• Due diligence: Before you sign a contract, invest in a company or hire a vendor, a quick search confirms the business is real and current with the state.
• Avoiding filing rejections: Wyoming won't register a new LLC under a name that's too similar to one already on file [3]. Checking first saves you a rejected filing and a second $100 Articles of Organization fee.

A search here pairs naturally with a few other steps in the Wyoming LLC process.
