Colorado Business Entity Search (LLC, Corporation, Partnership)

Colorado State ImageThe business division of Colorado Secretary of State maintains records of all the active/inactive business entities registered in the state.

Basic information about each business such as address, owners name, registered agent etc is freely available on the SOS website. One can directly carry out the search for business information on the Colorado Secretary of State website (no signup required).

However, conducting business entity search for first-time users can be confusing as the SOS website is difficult to navigate. Also, the complex terms used in the search report may be a bit difficult to understand.

For this very reason, we’ve put together this guide, to help you carry out the search and make most out of it.

Let’s start:

The SOS database has information about all the Corporations, Limited Partnerships (LP), Limited Liability Companies (LLC), Limited Liability Partnerships (LLPs) and trademarks registered in the state.

Note: Information on Sole Proprietorships is not available here.

Searching for a business entity can be helpful for users and business owners in the following ways:

  1. Business name availability check – No two businesses can have the same name. Using the name search, one can check for business name availability.
  2. The legal existence of company – Customers, vendors or competitors may want to check if the company they are dealing with is legally registered in the state or not.
  3. Status of the company – Whether the business is in good standing with the state or has the license expired.
  4. Download certified copies/file amendments etc.
  5. What is the current address of the business?
  6. Who is the registered agent and what is his/her address?
