Wyoming business entity information, including entity name, type, number, and formation date, is available through the Wyoming Secretary of State free business portal. The database provides immediate access to the details you need for onboarding, compliance tracking, or business transactions.

The portal operates within the WyoBiz Business Center and requires no account creation or fees. Results load dynamically after executing a search, and each entity record links to a detail page with filing history and current status.

Summary table: finding your Wyoming entity information

This table shows where to find each piece of entity information and what format to expect.

How to search for Wyoming business entities

The Wyoming business entity search portal lets you look up any registered business by name or Filing ID with no account required. For name searches, enter the business name in the "Filing Name" field and select either "Starts With" or "Contains" as the matching option. If you know the Filing ID, enter it directly for an exact match. Click any result to view complete details, including formation date, Wyoming registered agent information, and filing history.

The Wyoming SOS also links two reference documents from the search page: a Name Search Tips PDF and a How to Choose a Company Name guide, both hosted at sos.wyo.gov.

How to find your entity number in Wyoming

Your Wyoming entity number, officially called your Filing ID, is assigned when your entity is formed. Per the SOS Update Form, the Filing ID is "the identification number assigned to the filing by the Secretary of State's Office" and covers business entities, trademarks, and trade names.

Where to locate your Wyoming Filing ID

The Filing ID appears in three primary locations:

• Wyoming business search (fastest method): The Filing ID appears in the left column of search results as a clickable link.

• Certificate of Organization/Incorporation: Usually at the top of the document, labeled "File Number" or "Filing ID," stamped with the Wyoming Secretary of State seal.

• The WyoBiz annual report wizard and state correspondence: The Filing ID appears on all official SOS documents and serves as your account identifier for state filings.

Wyoming entity number format

Filing IDs typically appear as a numeric prefix, a hyphen, and a zero-padded sequence number (for example, 2000-000123456). The Wyoming Secretary of State has not published an official format specification, so character length and prefix conventions may vary across entity types and filing eras. The formation year cannot be determined solely from the prefix; no official SOS documentation confirms that the prefix reliably corresponds to the formation year. Confirm your exact Filing ID against the official business record or by contacting the SOS Business Division at 307.777.7311 or SOSRequest@wyo.gov.

How to find your entity type in Wyoming

Wyoming recognizes a broad range of entity types. According to the Wyoming SOS business statutes index and the Choice is Yours publication (Revised 2025), these include Profit Corporations, LLCs, Close LLCs, Low Profit LLCs (L3Cs), Decentralized Autonomous Organization LLCs, Limited Partnerships, Nonprofit Corporations, Statutory Trusts, and others. Those forming an LLC in Wyoming should note that the portal displays the full designation, such as "Limited Liability Company."

Your entity type appears in the "Type" column of search results, at the top of your Certificate of Organization or Incorporation, and in the entity information section of annual reports. The type cannot be changed without a formal amendment through the Secretary of State.

How to find your formation date in Wyoming

Your formation date appears in Wyoming business search results as "Filed date" and on your Certificate of Organization or Incorporation. This date marks when your entity legally came into existence. It also appears on Wyoming annual report filing confirmations and is used to calculate annual report due dates by state based on formation anniversary. Wyoming annual reports are due on or before the first day of the anniversary month, per the SOS "What's Next" guidance.

Formation date vs. effective date

By default, the formation date and effective date are the same. For LLCs, W.S. 17-29-201(e)(i) provides that a limited liability company is formed when the articles of organization become effective, subject to any delayed effective date specified under W.S. 17-29-205(c). For corporations, W.S. 17-16-203(a) provides that corporate existence becomes effective when the articles are filed, unless a delayed date is specified.

Wyoming permits a delayed effective date up to 90 days after filing under W.S. 17-16-123 (corporations) and W.S. 17-29-205(c) (LLCs). If a delayed date is specified, the entity does not legally exist until that date arrives, and the filer retains a cancellation right per W.S. 17-29-201(e)(ii). Retroactive effective dates are not authorized. The portal's "Filed On" date reflects when documents were filed, not necessarily when a delayed effective date takes effect.
