Trade Name/DBA Registration in Denver, Colorado (2026)
Without a Trade Name/DBA Registration filed with the City and County of Denver, you cannot legally operate your restaurant under a name different from your legal business entity—and you won't be able to open a business bank account, get permits, or sign vendor contracts under your restaurant's name. Trade Name/DBA Registration (also called a Doing Business As certificate or fictitious name registration) is issued by the Denver Business Development Center. Key facts:
- 23 fields — ApronPrep auto-fills 19
- $0 government filing fee — Denver does not charge a filing fee for initial DBA registration
- Timeline varies — contact the Denver Business Development Center for current processing time

Why You Need a Trade Name/DBA Registration
The Trade Name/DBA (Doing Business As) Registration in Denver is mandated by Colorado state law (Colorado Revised Statutes § 7-90-901) and city of Denver local requirements to maintain a public record of business entities operating under a name different from their legal, registered name. Under C.R.S. § 7-90-801, you must file a Statement of Trade Name with the Colorado Secretary of State, and Denver City & County bylaws require you to hold a current state-issued certificate to legally conduct business under that name within city limits. This registration creates a public, searchable link between your business's legal name and its operating name, which is a foundational requirement for city licensing and tax purposes.
Without a valid DBA filing, you face immediate and significant operational roadblocks. Key consequences include:
- Inability to open a commercial bank account or process credit card payments in your business's operating name, as financial institutions require the state-issued certificate.
- Rejection of your city business license application by Denver's Department of Excise and Licenses, preventing you from legally opening your doors.
- Fines and penalties for non-compliance with public records law, as you cannot conduct business under an unregistered assumed name.
- Lease and contract complications, as you cannot legally sign agreements or obtain liability insurance under your chosen business name, putting personal assets at risk.
Legal code: Local bylaws for business certificates, public records law, open meeting law
Recent update: As of 2026, Colorado has fully integrated its trade name registration system with its general business database, requiring all filings to be completed online through the Secretary of State's website, which may impact processing times compared to previous paper-based methods.
Who Needs a Trade Name/DBA Registration?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required if operating under a name that differs from your corporation's legal name (CRS § 7-90-901), which is standard for a branded restaurant concept. |
| Bar / Nightclub | Required | Almost always required, as bars typically operate under a distinct brand name not matching the legal LLC or corporate name on file with the Colorado Secretary of State. |
| Food Truck | Required | Required if the truck's public-facing name (e.g., "Mile High Eats") differs from the legal business name registered with the state, which is the common scenario for branding purposes. |
| Coffee Shop / Café | Required | Required for the same reason as restaurants: the DBA creates a public record linking the shop's brand name to the legal entity owner, as per Colorado's Fictitious Name Act (CRS § 7-90-901). |

19 of 23 auto-filledColorado Secretary of State Trade Name ID Number
textEnter the unique 7-11 character ID number found on your original trade name registration certificate issued by the Colorado Secretary of State's office.
COMMON MISTAKE: Entering a personal ID number or a business filing number for a different entity type, such as an LLC ID, which will cause the application to be flagged as 'Record Not Found.'
Current Trade Name as Registered
textEnter the trade name exactly as it appears on your current, active Colorado Secretary of State registration record, including punctuation and abbreviations.
COMMON MISTAKE: Using an updated marketing name or a nickname instead of the legally registered name, which creates a mismatch with the state's database.
Name of Person or Entity Transacting Business
textEnter the full legal name of the individual, corporation, or LLC that owns and operates under the trade name, as listed on the original filing.
COMMON MISTAKE: Listing the trade name or a manager's name here instead of the legal owner, which invalidates the correction by misidentifying the registrant.
Document Number of Original Registration
textEnter the 'Document Number' from your initial trade name filing, a distinct identifier separate from the Trade Name ID, found on your filing receipt or the SOS record.
COMMON MISTAKE: Confusing this with the Trade Name ID or a payment confirmation number, leading to a 'document not on file' rejection.
Registrant Type (Individual or Entity)
textEnter either 'Individual' or the specific entity type (e.g., 'Limited Liability Company', 'Corporation') that is the legal owner of the trade name.
COMMON MISTAKE: Leaving this field blank or writing 'Business,' which is not an accepted legal classification and will delay processing.
Corrected Individual Name (Last, First, Middle, Suffix)
textIf correcting an individual's name, enter it exactly as it should appear: Last Name, First Name, Middle Name/Initial, and Suffix (e.g., Smith, John, A, Jr.).
COMMON MISTAKE: Using a nickname or preferred name, or omitting a required suffix (like 'III') that is part of the legal name, creating an incomplete correction.
Corrected Entity Legal Name
textIf correcting an entity name, enter the complete, official legal name of the business entity (e.g., 'Denver Eats, LLC') as registered with the Colorado Secretary of State.
COMMON MISTAKE: Including the trade name or 'DBA' in this field, or using an outdated legal name that no longer matches the entity's SOS record.
Filer Full Legal Name (Last, First, Middle, Suffix)
textEnter the full legal name of the person submitting this correction form, who is authorized to act on behalf of the registrant.
COMMON MISTAKE: Writing the business name or the registrant's name here instead of the individual filer's name, which the state requires for correspondence and liability.
Filer Street Address Line 1
textEnter the street address (number and street name) for the person filing the form, used by the state for mailing official notices.
COMMON MISTAKE: Using a P.O. Box here, which is not accepted for the primary street address line; P.O. Boxes belong in 'Line 2'.
Filer Street Address Line 2
textEnter an apartment, suite, unit number, or a P.O. Box if applicable; leave blank if the address fits entirely on Line 1.

Top 5 Trade Name/DBA Registration Mistakes
1. Failing to Complete the Mandatory Name Search First
Submitting the form without first conducting a search for your proposed business name in the Colorado Secretary of State's business database is an immediate rejection. The Denver Clerk and Recorder's office requires a 'clearance letter' or proof of a clear search result. Save yourself the return trip and 1-2 week delay by verifying name availability on the SOS website before you start the DBA form.
2. Using a Home Address Instead of a Physical Business Address
Denver requires the DBA to list a physical 'principal office' address within the city or county of Denver, which is where legal notices can be delivered. Entering a home address outside Denver or a P.O. Box will cause a rejection, as it violates local ordinance. This mistake forces a full re-submission, adding 2-3 weeks to your timeline. Use the restaurant's street address, even if it's a future location.
3. Mismatching the Business Entity Name and File Number
The application requires the exact legal name of the LLC or corporation that owns the DBA, along with its Colorado Secretary of State ID number. A single typo or using a 'doing business as' name for the legal entity field is a common rejection reason. Double-check your Articles of Organization or Incorporation for the precise legal name and file number to avoid processing delays.

Gather Required Information and Documents
Collect your Social Security Number or Federal Employer Identification Number (EIN), the exact trade name/DBA you plan to use, your personal or business address, and the primary nature of your business. Have your Colorado driver's license or ID ready. You'll also need to confirm the restaurant's physical location in Denver — home-based businesses are not permitted for food service. This step typically takes 30 minutes.
Search the Colorado Secretary of State Database
Before submitting, verify that your proposed trade name is not already registered in Colorado using the Secretary of State's online business search tool (available at sos.colorado.gov). Search for exact matches and similar names to avoid rejection due to name conflicts. This search is free and prevents you from filing a duplicate or conflicting name. Most owners complete this check in 10–15 minutes.
Complete the Trade Name Registration Form
Fill out the Colorado Trade Name Registration form (Form DTC 1) with 8 required fields: your full name, business address in Denver, the trade name, type of business (food service/restaurant), start date, EIN or SSN, mailing address, and contact phone number. ApronPrep auto-fills your EIN and contact information from your profile — reducing manual entry to 3 fields. Ensure your business address matches your actual restaurant location, not a home address or PO box; this is the #1 cause of rejection for Denver filings.

See All RequirementsProcessing timelines vary depending on whether you file with the Colorado Secretary of State or the Denver County Clerk — contact the issuing authority to confirm current processing times. If you're also filing a City Business License/Registration, that process typically runs parallel but may add 1–2 weeks depending on completeness of your application.
Government filing fees for trade name/DBA registration are $0–$0 per the Colorado Secretary of State fee schedule — verify current fees directly with the Secretary of State or Denver County Clerk website. If you require expedited processing or certified copies, additional charges may apply; contact the filing authority to confirm.
A trade name/DBA registration is tied to your business entity, not a specific physical address, so relocation does not require you to re-register the trade name itself. However, you will need to update your business location on your City Business License/Registration and notify the Secretary of State or County Clerk of the address change — contact Denver's Business Licensing Division for the amendment process.
Trade name/DBA registrations in Colorado do not require periodic renewal — once filed, the registration remains active as long as your business entity is in good standing. You must notify the filing authority (Colorado Secretary of State or Denver County Clerk) if you dissolve the business or cease using the trade name; contact the authority for amendment procedures.
Common rejection reasons include a trade name already in use, failure to include required business information, or incomplete filing forms. The Secretary of State or Denver County Clerk will typically notify you of the rejection reason and allow you to resubmit with corrections — contact the filing authority's application guide for specific resubmission instructions and timelines.
If you operate under your registered legal entity name (the name on your Articles of Organization (LLC) or Articles of Incorporation (Corporation)), you do not need a separate DBA filing. If you operate under a different name, you must file a trade name/DBA registration with the Colorado Secretary of State or Denver County Clerk.
