General Rules for Corporation Names

These rules generally apply to all corporations, wherever they're formed.

1
Your Corporation Name Must Be Unique

The name you choose cannot be in use by any other business in the state. This is why it's so important to perform a Colorado State corporation search before you begin your incorporation paperwork.

2
Your Corporation Name Must Not Be Confusable with Another Business Name

It’s not enough for your corporation name to be unique. It also cannot be comparable to the name of another business in the state. In addition, you cannot use any of the following features in an attempt to differentiate your corporation name from that of another business:

  • Suffixes, such as Corporation, Company, Incorporated, Incorporation, Limited, Corp., Co., Inc., etc.
  • Definite articles, such as “A,” “An” or “The”
  • The conjunction "And" or “&"
  • Numbers in place of numerals (or vice versa), e.g., "One World" is the same as "1 World"
  • The singular, plural or possessive forms of words
  • Abbreviations, punctuation, symbols, fonts, typefaces, etc.
3
Your Corporation Name Must Contain Certain Words

All corporations must use one of the following in their names, usually at the end of the name: “Incorporated,” “Corporation,” “Limited” or their abbreviations.

4
Your Corporation Name May Be Subject to Other General Restrictions

Most states will not allow you to incorporate with names that:

  • Are similar to the name of a federal or state agency or organization (e.g., FBI, FDA, Colorado Department of Labor, Colorado Rangers, Treasury, etc.)
  • Suggest affiliation with a federal or state agency or organization
  • Use the term “Olympic” or any terms that are trademarks of the International Olympic Committee
  • Imply a purpose that would be illegal for your business to carry out

Specific Rules for Colorado Business Names

In addition to the general rules listed above, you'll need to follow some Colorado corporation laws that apply to naming your business.

For example, per the Colorado Revised Statutes C.R.S. 7-90-601, "the entity name of a corporation shall contain the term or abbreviation “corporation”, “incorporated”, “company”, “limited”, “corp.”, “inc.”, “co.”, or “ltd.”".

Trademarks and Service Marks

You must be careful that your Colorado corporation name doesn't infringe on the trademark or service mark of another business. The easiest way to ensure you're not infringing is to perform a trademark search through Incfile. If you want the trademark for yourself, you can register it if it isn't already in use.

Make sure your corporation is starting off on the right foot when it comes to intellectual property.

Let Incfile run a trademark search for you.

 

Register a DBA in Colorado

In Colorado you may do business under a name different from your corporation's legal name. While many states refer to this as an assumed name, fictitious name or "doing business as" (DBA), it's a trade name in Colorado. You may decide to use a trade name for a variety of reasons.

For example, your primary business may be called Mountain Media, Inc., and you have a chain called Mountain Mobility. You could register a trade name just for that brand. You'd do that by filing a Statement of Trade Name, which must be filed electronically with the Secretary of State. Or you can have Incfile do it on your behalf with our DBA service.

In order to keep your business names unique, you can also use the Colorado business entity search. You can perform a Colorado trade name search to find out whether any other companies are already using your desired trade name. We can also help you with this via our DBA name service.

Note: A trade name is not the same as a trademark. Learn more about trademark vs. DBA.
