How To Perform a Wyoming Business Entity Search

The Wyoming Secretary of State keeps a free public record of every registered business in the state through WyoBiz, its Business Division portal. Wyoming forms more out-of-state LLCs than almost any state its size, on a reputation for privacy and low cost, which means a lot of people searching this database have never set foot in Wyoming and don't know its naming rules by instinct. Wyoming's rules are also genuinely unusual in places: its name comparison logic strips out Latin plural forms most other states don't check, and its list of recognized entity designators includes DAO and LAO alongside LLC and Inc, a reflection of Wyoming being the first state to write blockchain-based entities into its business code.

Key Takeaways

A name reservation costs $60 for either an LLC or a corporation, and holds the name for 120 days. It cannot be renewed, and it must be filed by mail. [2][3]

A Trade Name registration lasts 10 years. Renew within six months before it expires for another 10-year term. [4]

Wyoming's name comparison strips out far more than most states check. Articles, conjunctions, punctuation, capitalization, and even Latin-rooted plurals like "cacti" versus "cactus" are all ignored when comparing two names. [5]

A dissolved name doesn't stay locked forever. It opens back up immediately if the entity was dissolved, or after two years if it was Administratively Dissolved. [5]

What the Wyoming Business Database Covers

WyoBiz is the Secretary of State's public record of every entity, Trade Name, and trademark registered in the state. It confirms an entity's registration, its status, its registered agent, and its filing history. It does not include federal trademark rights, and it does not include UCC lien filings, which run through a separate UCC/EFS search system on the same site. [8]

What You Will Find:

• Limited liability companies: Domestic and foreign LLCs, Series LLCs, and DAO LLCs, a distinct entity type Wyoming created for blockchain and decentralized organizations.
• Corporations: For-profit corporations, nonprofit corporations, and processing cooperatives.
• Partnerships: Limited partnerships and registered limited liability partnerships.
• Statutory trusts and statutory foundations: Two entity types Wyoming offers that most states do not.
• Trade Names and state trademarks: Searchable in the same system as entities.

What Is Not in the Database:

• Federal trademarks: WyoBiz only reflects state filings, never the federal trademark register.
• UCC lien filings: These run through Wyoming's separate UCC/EFS system, not the entity search. [8]
• Tax account numbers: A federal EIN comes from the IRS, and a Wyoming sales tax license comes from the Department of Revenue. Neither appears here.
• Unregistered sole proprietors: A sole proprietor operating under their own legal name files nothing and appears nowhere in WyoBiz.

How To Perform a Wyoming Business Entity Search Step-by-Step

Step 1. Open WyoBiz

Go to WyoBiz Business Entity Search. No account or fee is required to search.

Step 2. Search by Name or Filing ID

Type in the business name or the filing ID number and run the search. A filing ID search returns exactly one record with no ambiguity.

Step 3. Select "Contains" and Strip the Name Down

Wyoming's own guidance recommends the "Contains" search option, then comparing only the words the state actually treats as distinguishable. [5] Before comparing results:

• Drop the entity designator: Corp, Corporation, Inc, Incorporated, LLC, Limited Liability Company, LP, Statutory Trust, DAO, and similar terms are all ignored in a distinguishability comparison.
• Drop "Company," "Co," "The," "And," "&," and "A." None of these carry weight in the comparison either.
• Ignore spacing, capitalization, and punctuation. "Wildwood" and "Wild Wood" compare as identical, and so do differences in case or special characters.
• Check singular and plural forms, including Latin-rooted ones. Wyoming's guidance specifically flags pairs like Property/Properties, Cactus/Cacti, and Maximum/Maxima as equivalent for comparison purposes. [5]

Step 4. Open the Record and Read the Details

Selecting a result opens the full record: entity type, filing ID, status, formation date, registered agent, and principal office address.

Step 5. Confirm the Result Against the Naming Rules

A name that comes back clear in the search still has to pass Wyoming's distinguishability standard when the Secretary of State actually reviews a filing, typically the next business day after it's submitted. [5] Treat a clear search as a strong signal, not a final answer.

How To Read Your Wyoming Entity Search Results

What Wyoming Entity Statuses Mean

A Delinquent or Dissolved status on a company you're evaluating, rather than one whose name you want, is a signal to ask questions before you rely on it. Swyft Filings handles Wyoming annual report filings if that's the issue keeping an entity you own out of Active status.

How To Check if a Business Name Is Available in Wyoming

1. Search the full proposed name in WyoBiz using the "Contains" option.
2. Search again using only the single most distinguishable word, dropping the entity designator and words like "Company" or "The."
3. Check both singular and plural forms, including irregular ones Wyoming specifically calls out, like Cactus/Cacti or Holding/Holdings. [5]
4. If a close match shows Inactive-Dissolved or Inactive-Administratively Dissolved, check how long ago that happened. A voluntarily dissolved name is available immediately; an administratively dissolved one needs two years. [5]
5. Search the federal trademark register separately, since Wyoming's search does not cover it.

If a name isn't distinguishable on its own, Wyoming's guidance is to add a genuinely distinguishing element, a numeral, a different word, or a spelled-out number, rather than relying on punctuation or spacing to set it apart. [5]

Wyoming LLC Naming Requirements and Restricted Words

An LLC name must include "Limited Liability Company" or an accepted abbreviation: LLC, L.L.C., Limited Company, LC, L.C., Ltd. Liability Company, Ltd. Liability Co., or Limited Liability Co. [2] A corporation's name must include Corporation, Incorporated, or an accepted abbreviation. A DAO LLC uses the same LLC designators, since it's formed under Wyoming's LLC Act with additional DAO-specific provisions.

Words That Require Additional Approval

The following require sign-off from a separate Wyoming agency before the name can be filed, and cannot be submitted through the online portal, only by mail: [5]

A clear search is not the same as approval. Availability is only settled once the Secretary of State processes and accepts the filing itself, typically the next business day.

Wyoming DAO LLC Search: Why You Might See "DAO" or "LAO" in Results

Wyoming was the first state to write decentralized autonomous organizations directly into its business code, and it treats a DAO LLC as its own recognized designation, alongside "LLC" and the less common "LAO," when comparing names for distinguishability. [5] A DAO LLC files its own Articles of Organization, its own name reservation, and its own amendment forms, separate from a standard LLC filing. [9]

If a WyoBiz search turns up an entity with "DAO LLC" in its name, it's registered under this specific statutory framework, not a standard LLC that happens to include the word. This is worth knowing if your search results include entities you don't recognize as a normal company structure.

Wyoming Foreign Certificate of Authority: Do You Need One?

A business formed in another state cannot legally "transact business" in Wyoming without first obtaining a Certificate of Authority from the Secretary of State. [10] This question comes up constantly for out-of-state owners who formed a Wyoming LLC and want to know whether they also need to register at home, or the reverse.

Activities that do not require a Certificate of Authority include maintaining bank accounts, holding internal board or member meetings, selling through independent contractors, an isolated transaction completed within 30 days, and transacting business in interstate commerce. [10]

If a Certificate of Authority is required, the application must include an original certificate of existence or good standing from the home state, dated within 60 days of filing in Wyoming and authenticated by that state's own Secretary of State. Separate application forms exist for foreign LLCs, corporations, nonprofits, limited partnerships, LLPs, and statutory trusts. [10] A company operating in Wyoming without the required authority is subject to back taxes and penalties under Wyoming statute. [10]

Wyoming Secretary of State Fees for Name Registration and LLC Formation

All figures below are from the Secretary of State's Business Division fee schedule and individual filing forms. [1]

How To Reserve a Business Name in Wyoming Without Filing Articles

If you're not ready to form your LLC or corporation yet, you can hold the name on its own first.

1. Confirm the name is clear in WyoBiz first, using the "Contains" search.
2. Complete the applicable Name Reservation form for your entity type. A DAO LLC uses its own separate reservation form. [9]
3. Mail it with payment to the Business Division.
4. File your Articles of Organization or Incorporation within the 120-day hold. If you're filing Articles right away, skip the reservation entirely, since it isn't required. [2]

How To Register a Trade Name (DBA) in Wyoming

Wyoming calls a DBA a Trade Name, and unlike states that push this filing down to the county level, Wyoming registers it centrally with the Secretary of State under W.S. §§ 40-2-101 through 40-2-109. [4]

1. Search WyoBiz to confirm the name is not already registered as an entity or Trade Name.
2. Confirm the name is already in use in Wyoming. Wyoming requires the Trade Name to be in active use before you can register it, unlike a standard entity name. [4]
3. If the applicant is a business entity rather than an individual, it must already be registered and in good standing with the Secretary of State. [4]
4. Complete the Trade Name Registration Application. It must be signed and notarized. [4]
5. Mail it with the $100 filing fee. No expedited option exists for this filing, so it processes in the order received, up to 15 business days. [4]
6. Mark the expiration date on your own calendar. The registration lasts 10 years, and the state emails a renewal reminder six months before it expires. [4]

A Trade Name never creates a new legal entity. It does not change your tax status, your liability protection, or your ownership structure.

Swyft Filings can handle your Wyoming DBA registration alongside your entity formation.

Wyoming Business Name Search vs. USPTO Federal Trademark Search

Clearing Wyoming's business search protects the name at the state level only. It says nothing about federal trademark rights. Wyoming checks a proposed name against other Wyoming filings alone, so a name can be fully distinguishable in Wyoming and still infringe a mark that a business in another state registered years ago with the USPTO.

Run both searches if the brand matters beyond Wyoming's borders: WyoBiz for state-level distinguishability, and the USPTO trademark database for a name that could be used or defended nationwide. Wyoming also maintains its own state-level trademark registration, separate from both of these.

Consequences of Using a Business Name Already Registered in Wyoming

• The filing gets rejected. If the Secretary of State determines a name is not distinguishable from an existing entity, reservation, or Trade Name, the filing simply does not go through.
• You lose the filing fee and the time. Reservation and formation fees are non-refundable, so a rejected filing means paying again for a corrected one.
• It creates no protection against a trademark claim. State-level clearance never defends against a company holding a federal trademark on a similar name.
• It invites confusion with the existing business, especially in a state like Wyoming where thousands of out-of-state LLCs share similar generic naming conventions.

Wyoming Business Name Availability for Nonprofit vs. For-Profit Entities

The search process is identical for both, and the naming rules, restricted words, and distinguishability standard apply the same way regardless of tax status. The cost differs: a nonprofit corporation's Articles of Incorporation cost $50 versus $100 for a for-profit corporation, and a nonprofit's annual report fee is a flat $25, while a for-profit entity's annual license tax starts at a $60 minimum and scales with in-state assets. [1]

How To Verify a Wyoming Company Before You Deal With It

1. Search the exact legal name printed on the contract or invoice, not the brand name on the sign.
2. Confirm the status reads Active rather than Inactive.
3. Save the filing ID, the status, and the date you checked.
4. Check the formation date against the years of experience the business claims.
5. Read the registered agent and confirm it's a real Wyoming address, not a PO box.
6. Check whether the brand name shown to you appears as a registered Trade Name of the entity.

Red Flags Worth a Second Look

• A company using LLC or Inc. in its name with no Wyoming record at all.
• An Inactive status behind a business presenting itself as fully compliant.
• A brand name that does not appear as a registered Trade Name of the entity you found.
• A registered agent address that looks like a mail drop rather than a real office.
