Why You Need a Trade Name/DBA Registration
In Aurora, Colorado, operating under a name that differs from your legal business entity requires formal registration with the City Clerk's Office. This is governed by local municipal code provisions on business licensing and the state's public records laws, which mandate that business identities be transparent and accessible. Registering your 'Doing Business As' (DBA) name creates a public record, linking your trade name to the official owner (e.g., your LLC or sole proprietorship). This is a foundational step for establishing your restaurant's public identity and is separate from state-level business formation.
Failing to register your DBA before opening creates immediate operational and legal roadblocks. Based on standard municipal enforcement, the primary consequences include:
- Inability to open a business bank account: Banks universally require a filed DBA certificate to open an account in your business's trade name, freezing your ability to process credit cards or manage finances separately from personal accounts.
- Fines for non-compliance: Operating under an unregistered name violates local business license ordinances, potentially resulting in monetary penalties and putting your broader business license at risk during inspections.
- Lease and contract complications: You cannot legally sign vendor contracts or a commercial lease in your restaurant's trading name, creating liability issues and potentially voiding agreements.
- Loss of legal recourse: You may be unable to enforce payment or defend your business name in court, as you lack official standing for the unregistered trade name.
Legal code: Local bylaws for business certificates, public records law, open meeting law
Recent update: As of 2026, Aurora has integrated its business registration portal with the state's business database, which may streamline verification but does not eliminate the local filing requirement.

COMMON MISTAKE: Omitting the legal suffix, using the DBA name, or including any punctuation or formatting not on the official state filing.
Trade Name/DBA
textEnter the 'Doing Business As' name you want the public to use for your restaurant, exactly as you plan to advertise it, which cannot already be registered by another business in Arapahoe County.
COMMON MISTAKE: Proposing a name that is already registered, includes restricted words like 'Bank' or 'University' without proper licensing, or uses an unincorporated legal suffix like 'LLC'.

textState the legal form of your business entity, such as 'Sole Proprietorship', 'General Partnership', 'Limited Liability Company (LLC)', 'Corporation', or 'Limited Partnership (LP)'.
COMMON MISTAKE: Entering informal descriptions like 'family-owned' or 'small business' instead of the precise, formal legal structure used when registering with the Colorado Secretary of State.
Type of Business or Business Description
textProvide a brief, clear description of your primary business activity, such as 'Restaurant - Full Service', 'Coffee Shop', 'Food Truck', or 'Catering Service'.
COMMON MISTAKE: Using overly broad terms like 'Food' or 'Service Industry' or listing multiple unrelated activities, which can complicate future zoning or licensing reviews.

COMMON MISTAKE: Using an old, inactive, or shared business email that may filter correspondence to spam, causing missed deadlines or notices.

Top 5 Trade Name/DBA Registration Mistakes
1. Providing an Insufficient or Inaccurate Legal Business Name
Entering an abbreviated or informal version of your LLC or corporation's official legal name as registered with the Colorado Secretary of State. For example, entering 'Aurora Pizza LLC' when the official legal name is 'Aurora Pizza Holdings LLC.' The Aurora City Clerk will reject the application because the DBA filing must perfectly match the legal entity name on state records, requiring you to submit a corrected form and adding 1-2 weeks to your timeline.
2. Selecting the Wrong Filing Location or Jurisdiction
Filing the Trade Name/DBA application directly with the Colorado Secretary of State, which is required for statewide registration, but neglecting to also file locally with the Aurora City Clerk if your principal place of business is within the city. Operating without the local filing exposes you to penalties per Aurora municipal code and can invalidate your ability to get a local business license, forcing a delayed dual filing and incurring additional government fees.
3. Using a Trade Name Already Registered in Aurora
Choosing a DBA name that is identical or confusingly similar to an existing, active Trade Name registration on file with the Aurora City Clerk. The clerk's office will deny your application. Before filing, you must search the Aurora Trade Name registry and the Colorado Secretary of State's business database. A rejected application due to name conflict adds at least 3-4 weeks as you must restart the process with a new name search and form.

Obtain the trade name/DBA registration application form from City of Aurora
Download the "Fictitious Name Registration" form (often form CF-06) directly from the City of Aurora's official Business Services Division website. Avoid generic state DBA forms, as Aurora requires its specific municipal registration. Have your business's legal name and Colorado Secretary of State business ID number ready to reference.
Complete the application form with all required business information
Fill out all fields, including your legal business name, the exact trade name/DBA you wish to register, and the principal business address in Aurora. Key details include the owner's name and contact information. ApronPrep auto-fills standard business data, reducing manual entry for most of the form's approximately 15-20 fields.
Prepare required identification and supporting documents
Gather a copy of your business's Colorado Secretary of State Certificate of Good Standing (or formation documents) and a valid government-issued photo ID for the filer. If the business is an LLC or corporation, you may need meeting minutes authorizing the DBA. Applications submitted without proof of the underlying legal entity's status are commonly rejected.

See All RequirementsThe City of Aurora does not publish a standard processing timeline for trade name registrations. Contact the city's Business License Division directly at (303) 739-7057 to confirm current processing times, as they can vary based on application volume and completeness. This registration is separate from your City Business License/Registration, which may have its own timeline.
The government filing fee for a trade name registration in Aurora is $0. This fee is set by the city and listed on its official application materials. Not legal advice — verify the current fee with the Aurora Business License Division before submitting.
No, a trade name registration is not transferable between business entities. If your business structure changes, you must file a new trade name registration with the City of Aurora. This is a key distinction from licenses like a Building Permit, which is tied to a specific property address.
Per the City of Aurora's requirements, a trade name registration does not require periodic renewal. It remains valid as long as the business is active and the name is in use. However, you must keep the registration information updated with the city if your business address or ownership changes.
There is typically no physical inspection for a trade name/DBA registration itself. The process is an administrative review of your application to ensure the name is not already in use in Aurora and is not misleading. Inspections are required for other operational permits, such as for health, safety, or construction, which are separate processes.
