Colorado DBA name Registration

Registering a trade name in Colorado is an easy process.

#1 Start with a Colorado DBA Name Search

Choose a unique Colorado trade name that meets all the Colorado business name requirements. You can visit the Colorado Name Availability Search website and look for a new DBA name and ensure it is not in use. Your Colorado trade name shouldn’t include the following:

  • A word or phrase that breaches Colorado law. For example: The business name should not include any references to illegal activities.

  • Words that confuse your business with the government agency like Treasury, FBI, State Department, etc.

You can check if your name is available as a web domain (URL). You may not start a business today but you can prevent others from taking the URL.

Also, if you haven’t thought of a DBA name yet, try using a free business name generator and create a free logo generator.

  • Streamline your business finances-

You must separate your business finances from your personal ones. It can be achieved by opening a business bank account and getting a business credit card.

Frequently Asked Questions​ (FAQs)

You can have as many DBAs as you can manage and keep track of. Every Doing Business As name comes with additional incremental expenses and paperwork.

A Doing Business As does not require an EIN as it is not a business entity. DBA under a business entity would have an EIN if it were necessary.

Applying for a DBA is much better than going for a legal name change. You can rebrand your company or add another line of business just with a DBA.

Some state laws prevent the use of similar DBAs. To avoid this, you can trademark the trade name to offer stronger protection.

A trade name can have an INC. in the name only if it is attached to a corporation.
