Even with the help of business services through the Secretary of State, registering a business has financial consequences. Always discuss business setup with a business attorney.

How to search for Colorado business names

Before registering a business, a business owner needs to search the Colorado Secretary of State’s database for the business entity name availability. A name cannot be the same as another name, nor can it be similar to another business’s name. To search the database, enter search criteria as follows:

  • Step 1: Navigate to the Colorado Secretary of State’s search tool.
  • Step 2: Enter the entity name.
  • Step 3: Click the ‘Search’ button.
  • Step 4: If the search tool returns no results, the name is most likely available.
  • Step 5: If the system returns results, it will return a clickable file number or entity number, the name of the business, and the business’s address. If the business owner does not find an exact match, he should review all records for similar names. For example, Aldi Enterprises and Aldi LLC are similar names, so the business could not use ‘Aldi.’

How to register a business name in Colorado

Colorado makes registering a new entity name easy. Everything you need is in one place, and the business owner does not need to create an account.

  • Step 1: Navigate to the Colorado Secretary of State’s business formation page.
  • Step 2: Choose the type of entity. If a business owner is not sure which entity is the best for his business, he should contact a business law attorney. Some entities offer more personal asset protection while some offer none. The Internal Revenue Service also taxes entities differently.
  • Step 3: Click the link to the correct form. To form an LLC, click ‘Limited Liability Company.’ To register a trademark, click ‘Register a trademark.’ To form a for-profit corporation, click ‘Profit Corporation,’ and so on.
  • Step 4: The link the business owner clicks will take her to a new page with instructions to form the entity, filing fees, how to pay the filing fees, and additional information. Follow the instructions for the entity you chose.

Colorado trademark/DBA name search

A business owner might want to register a logo, a trade name or other intellectual property. He can register intellectual property at the state level. However, the business owner must search the trademark database to ensure that no other intellectual property that is the same or similar exists. To search the Colorado trademark database:

  • Step 1: Navigate to the Colorado Secretary of State’s trademark search tool.
  • Step 2: Leave the restriction dates blank.
  • Step 3: Tick the box for trade name or trademark for search type.
  • Step 4: Enter the trade name or a descriptive keyword.
  • Step 5: Leave the ‘Exact match’ box unchecked.
  • Step 6: Tick the ‘I’m not a robot’ box for the CAPTCHA.
  • Step 7: Click the ‘Search’ box.

When a business owner registers intellectual property in Colorado, it is not protected outside the state. If the business owner needs national protection, he must file it at the national level. If a business owner wishes to determine whether a business name or logo has been trademarked at the federal level, search the United States Patent and Trademark Office.

Check if the domain name is available

Before a business registers its name, the business owner should take additional steps to ensure that the name is available for domain and social media use. While the domain name and social media accounts or pages do not have to have the same name as the business, it is better for marketing purposes. If another person or entity is already using the name, a prospective business owner can choose another name to register at the state level or use a different name that describes the business for the domain name and social media accounts.

If a business owner wishes to have an internet presence, she must check a domain registrar, such as GoDaddy, to determine if the business name is available.

If a domain name is not available

  • Choose another domain name that describes the business.
  • Pick another business name if the owner has not registered the name with the Colorado Secretary of State and does not mind picking a different name.
  • Choose a domain name that is similar to the existing name. However, don’t make it too similar, or customers will end up at a competitor’s website.
  • Additionally, if a dot-com is not available, but a dot-net is, do not use the name. Customers will end up on the competitor’s site.

Finally, when the business owner finds a website name that he can work with, register it immediately. During the registration process, select additional extensions, especially dot-net and dot-store.

Once a business owner finds an acceptable name, we recommend registering it immediately. Someone else could easily register a domain under your business name.

Check if the social media name is available

Social media platforms give a business an inexpensive way to market. A business owner only has to enter the business name in the search box to determine if someone else is using the name. If not, create an account for the business immediately – before someone else takes the name.

If someone is using the name, use a descriptive name for the business or consider picking a new business name if you haven’t yet registered the business with the state. A business owner could also use a similar name – but ensure that it isn’t so similar that it will send customers to a competitor.

Naming considerations for Colorado business entities

Colorado requires business owners to append certain phrases, words, or abbreviations to the end of a business name or it will reject the filing.

Sole proprietorships and partnerships

Sole proprietorships and general partnerships do not have to register with the Colorado Secretary of State. They must, however, use the business owner’s name as the business name. Partnerships must use the partners’ surnames.

If a sole proprietorship or general partnership wishes to conduct business under another name, it must register the ‘doing business as’ (DBA) name.
