Naming Your Colorado Limited Liability Company

You need the right name for your Colorado LLC. Choosing the right name is vital because it tells your suppliers, customers and employees what your business does. Colorado has several rules and regulations about what you can call your new business. Let’s explore what they are.

General Colorado Secretary of State Rules on Naming Your LLC

  • The name needs to be unique and not used by another LLC or business operating in Colorado
  • Colorado LLC names must use the English alphabet or regular numerals (0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
  • The name of your Colorado business must end with:
  • “Limited Liability Company”
  • “Ltd. Liability Company”
  • “Limited Liability Co.”
  • “Ltd.”
  • “Liability Co.”
  • “Limited”
  • “L.L.C.”
  • “LLC”
  • “Ltd.”

Don't Confuse Your Colorado Business Name With Another Business Name

  • The following terms can’t be used to make your business name different from another business name:
    • Suffixes like Corporation, Company, Incorporated, Incorporation, Limited, Corp, Co, Inc, Ltd, LLC.
    • Definite articles like “A," “And,” “An,” “&,” “The,” etc.
    • The singular, plural or possessive forms of a word
    • Punctuation and symbols
    • Abbreviations of words
    • Different typefaces, fonts, superscript, subscript, etc.
  • It should not be possible to confuse the name of your business with the name of another Colorado business.
  • For example, you can’t claim that Blue Widget Co., Blue Widget LLC, Blue Widget Incorporated, Blue-Widget-Company or Blue Widget are different from one another.

Rules on Words You Can’t Use in Your Business Name

  • Certain restricted words need additional paperwork if you want to use them in your business name. This list includes Bank, Banc, Banker, Banking, Banque, Credit Union, Trust or Savings and Loan.
  • You cannot use certain prohibited words that would confuse the name of your LLC with a federal or state agency, e.g. IRS, EPA, Treasury, etc.
  • You can also be a Colorado LLC with a different “doing business as” name. In Colorado these are known as “Trade Names” and need to be registered with the secretary of state. Learn about trade names in Colorado.

Colorado Information on Naming an LLC

  • In Colorado, you can reserve a name online. Please note that you do not need to reserve a name if you are forming an LLC. By registering a LLC, the name will automatically be reserved for your business. You would normally only reserve a name if you are not planning on forming a new company anytime soon.
  • Just filing a name registration doesn’t guarantee you will be granted the name. You should wait until your LLC is officially formed before using the name for anything else.

Rules on Infringing on Service Marks or Trademarks Inside or Outside Colorado

In addition to the rules above, it’s also vital to see if your Colorado LLC name might infringe on the trademark or service mark of another business. For example, it might not be a good idea to call yourself “Google Search Optimization Services,” since Google is a trademark.

The easiest way to see if your proposed business name infringes is to carry out a trademark search. You can do that via the United States Patent and Trademark Office, or Incfile can help you protect your business with our new trademark search and registration service. You should also bear in mind that your Colorado business entity name cannot be substantially similar to an existing trademark or service mark.

How to Search for Your Colorado Business Entity Name

Search the database of the Colorado Secretary of State for your proposed business name to see if it's unique.

You can search for:

  • Business name
  • Trade name
  • Trademark
  • Registered agent name
  • Registrants
  • Specific filing dates

What Should You Call Your Colorado LLC?

Finding the perfect name can be tough. You want a business name that:

  • Describes what your Colorado business does
  • Appeals to your planned audience
  • Makes your business easy to find
  • Is relatively unique
  • Doesn’t limit you to a particular location or type of product or service

Fortunately, we’ve got some good advice on seeking out the perfect business name for your Colorado LLC. Check out our guidance on naming your LLC and get inspired.
