Wyoming Secretary of State Business & Name Search: How to Search and Verify a Wyoming Entity
The Wyoming Secretary of State keeps the public record of every business entity formed or registered in Wyoming. This guide explains how to run a Wyoming business name search, check Wyoming LLC name availability, and read an entity’s filing details — all free, on the state’s own website.
What Is the Wyoming Secretary of State Business Search?
The Wyoming Secretary of State business search is the state’s free, public database of Wyoming entities. It returns the legal name, filing ID, status, formation date, and registered agent of record for any LLC, corporation, trust, nonprofit, or partnership on file.

- What it shows — legal name, Wyoming business registration number (filing ID), status, formation date, and the registered agent search result for each entity.
- Wyoming LLC name search — confirm whether a name is available before you file, and check the exact spelling of an existing Wyoming company on the register.
- Cost — the Wyoming Secretary of State business search is free; you do not need an account to look up a Wyoming entity.

How to run a Wyoming SOS business search
Open the Wyoming Secretary of State business search at the state portal, wyobiz.wyo.gov. Enter the entity name or filing ID. The secretary of state Wyoming business search returns matching entries on the Wyoming companies register, each linking to a filing details page. However you phrase it — the SOS WY business search, a WY LLC name search, or a Wyoming Secretary of State business filing lookup — it queries the same Wyoming LLC Secretary of State record, and a Wyoming registered agent search on that page shows the agent of record.
On the filing details page you can read the entity’s status, formation date, principal office, and the registered agent of record. This is the same public record a bank, court, or counterparty uses to confirm a Wyoming entity independently of the entity’s own website.

Checking Wyoming LLC name availability before you file
Before you form a Wyoming LLC, run a Wyoming LLC name search to confirm the name is distinguishable on the record from every existing Wyoming entity. A name that is already in use, or not distinguishable from one, will be rejected at filing.
A Wyoming LLC name must contain a permitted designator — “Limited Liability Company,” “LLC,” or “L.L.C.” The Wyoming business name search tells you whether your proposed name and its designator are free to use.
Reading a Wyoming filing details page
Each Wyoming entity has a Wyoming business registration number (its filing ID) and a public filing details page. That page shows the registered agent search result — the agent listed to receive service of process for the entity — alongside status and formation date.
If you are verifying a registered agent, the filing details page is the authoritative source: it shows exactly how an agent, such as Wyoming Registered Agent Prime LLC, is listed as the registered agent of record for a Wyoming entity.
