How to Search Available LLC Names in Colorado

1. Check Colorado LLC Naming Guidelines

Before you do a name availability search, it makes sense to check if your business name meets the basic state guidelines.

Some key guidelines for Colorado LLC names include:

  • Your name must include one of the following terms or abbreviations: limited liability company, ltd. liability company, limited liability co., ltd. liability co., limited, l.l.c., LLC, or ltd.

  • Your name must be distinguishable from any existing business in the state.

  • Your name cannot contain any term that would violate any Colorado law. For example, your business name cannot include obscenities or references to illegal activities.

Keep an eye out for restricted words. These words, such as “FBI” or “Treasury,” are often restricted to keep your LLC from sounding like an official institution.

For more information, check out Colorado’s official state statutes.

2. Complete an LLC Business Name Search

Once you know your LLC name meets Colorado guidelines, it’s time to make sure it’s available by using the Colorado Name Availability Search tool.

It is important that your name be distinguishable from all other business names. In Colorado, a distinguishable name is one that is substantially different from other names.

In addition to using different words, the following differences will make a name distinguishable in Colorado:

  • Use of articles (e.g., the, a)
  • Business type identifiers (e.g., LLC and Limited Liability Company are considered distinguishable)

The following differences will NOT make a name distinguishable in Colorado:

  • Periods (.), commas (,), underscores ( _ ), apostrophes (‘) and inverted apostrophes (`)
  • The case of letters

Failure to use a distinguishable name could result in your formation filing being rejected.

How to Reserve or Register Your Business Name

Reserve Your Name

You can optionally reserve your LLC name in Colorado for up to 120 days before you officially register it. This prevents other businesses from registering your name until you have the opportunity to register it yourself.

Name reservations can be filed online with the Colorado Secretary of State. The filing fee is $25.

Register Your Name

If you want to register a legal entity name for your LLC, you can do so at the time of formation filing. Colorado provides a section for your desired LLC name on the Articles of Organization.

Registering a DBA (doing business as) name, called a trade name in Colorado, is a separate process that requires filing with the Secretary of State.
