Colorado business name search

Colorado's Secretary of State runs a single Business Database Search that covers business names, trademarks and trade names, plus a separate name availability search. An entity name has to be distinguishable from names on record. Trade names don't, so a DBA filing alone never locks up a name in Colorado.

How to check if a name is available in Colorado

  1. 01

    Start in the Business Database Search

    Search by business name. The same tool also covers trademarks, trade names, ID numbers and document numbers, so one pass shows you most uses of the name on state records.

  2. 02

    Run the name availability search

    From "More search options", choose Name availability search. Enter the name with the term or abbreviation you plan to use (for example LLC); Colorado counts the designator when comparing names.

  3. 03

    Read the result with trade names in mind

    A matching trade name doesn't block your entity name, because trade names aren't distinguishable or unique in Colorado. It does mean someone is already using that name in the market.

  4. 04

    Check entity status

    Colorado entities show statuses such as Good Standing, Noncompliant, Delinquent or Dissolved. A Delinquent or Dissolved company's name is still on record.

  5. 05

    Search USPTO and online availability

    Search https://tmsearch.uspto.gov/ for federal trademarks, then check the domain and social handles.

  6. 06

    Keep options open

Colorado business naming rules

  • An entity name must be distinguishable (different) from other entity names on record with the Secretary of State.
  • Most entities must include a term or abbreviation in the name (such as LLC or Inc.) under C.R.S. 7-90-601. A different abbreviation can make a name distinguishable, so "ABC, LLC" is distinguishable from "ABC, Limited Liability Company".
  • Only acceptable characters may be used in a business name.
  • Trade names are not checked for uniqueness. The same trade name can be filed by more than one business, and trade names can't be reserved.

Reserving a name

Colorado reserves a name for 120 days once you file a Statement of Reservation of Name, and you can renew it with a Statement of Renewal of Reservation of Name. A reservation only holds the name; it doesn't start a business. Check the current fee on the agency's site.

DBAs and trade names

Trade names (DBAs) are filed online with the Colorado Secretary of State. Trade names don't have to be unique, so more than one business can register the same one.

Frequently asked questions

How do I check if a business name is available in Colorado?

Use the Secretary of State's name availability search under "More search options" in the Business Database Search. Include the LLC or Inc. ending you plan to use, because Colorado counts it.

Can two Colorado businesses have the same trade name?

Yes. Colorado trade names aren't required to be unique, so several businesses can file the same one. Only entity names must be distinguishable.

Can I reserve a trade name in Colorado?

No. The Statement of Reservation of Name works for entity names only. Trade names can't be reserved.

Who has to file a trade name in Colorado?

A for-profit business that operates under a name other than its true name, or an individual not using their legal first and last name, must file a Statement of Trade Name online with the Secretary of State.

General information, not legal advice. Name approval is decided by the Colorado Secretary of State; a name showing as available in a search is not a guarantee it will be accepted.
