Why You Need a Trade Name/DBA Registration
A Trade Name/DBA (Doing Business As) Registration in Portland, Oregon, is required to legally operate your restaurant under any name other than your legal business name. This is governed by Oregon Revised Statutes (ORS) Chapter 647, specifically the state's Trademark Act, and Portland's local business licensing ordinances. While not a federal trademark, filing your DBA at the county level (Multnomah County) creates a public record of your business's operating name. This registration is a foundational step for establishing your brand's legal identity and is mandatory before you can apply for a City of Portland Business License under the correct trade name.
Operating without a properly filed DBA registration can lead to significant practical and legal hurdles:
- Inability to conduct basic business: Banks will refuse to open a business checking account under your trade name, preventing you from processing customer credit card payments or managing business finances separately.
- Compliance violations: You cannot legally enter into contracts, sign leases, or obtain insurance policies under your restaurant's brand name, putting your entire operation at risk.
- Legal and financial exposure: You may face fines for non-compliance with public records and business licensing laws, and lose the ability to legally enforce contracts signed under the unregistered name.
- Operational delays You will be unable to obtain your mandatory City of Portland Business License, which can trigger daily penalties and a cease-and-desist order from the Revenue Division.
Legal code: Local bylaws for business certificates, public records law, open meeting law
Recent update: As of 2026, Multnomah County continues to require initial DBA filings to be submitted in person or by mail, but renewal notices and certain amendments can now be processed online through the County Clerk's filing portal.

17 of 21 auto-filledRegistry Number (if previously assigned)
textEnter the registration number from a prior or pending application for this assumed name with the Oregon Secretary of State's Corporation Division; leave blank if this is a new filing.
COMMON MISTAKE: Leaving this blank when you have an existing registration number can result in application rejection for duplicate filing.
Assumed Business Name (DBA)
textEnter the exact trade name you intend to operate under, matching the name you've checked for availability with the Oregon Secretary of State's Business Registry.
COMMON MISTAKE: Using a name already registered to another Oregon business or failing to include required corporate designators like 'LLC' or 'Inc.' for incorporated entities.
Business Description (Line 1)
textProvide a primary, specific description of the goods or services offered, such as 'Full-service restaurant with bar' or 'Specialty coffee and pastry shop'.
COMMON MISTAKE: Using generic terms like 'food service' or leaving the field blank, which violates Oregon Revised Statutes § 648.007.
Business Description (Line 2)
textUse this optional line for additional descriptive details if needed, but do not repeat the same information from Line 1.
COMMON MISTAKE: Repeating the exact text from Line 1 or leaving blank if Line 1's description is insufficient, causing a 'Vague Purpose' rejection.
Authorized Representative Name
textEnter the full legal name (first, middle, last) of the individual authorized to sign for the business entity, typically an owner or corporate officer.
COMMON MISTAKE: Entering a business entity name or an unofficial nickname, which invalidates the signature authority per the Secretary of State's instructions.
Principal Business Address (Line 1)
textEnter the street number and name (e.g., '123 Main St') of the physical restaurant location in Portland; this cannot be a P.O. Box.
COMMON MISTAKE: Using a mailing address, home address, or incomplete street address, which fails the physical location requirement and triggers a rejection.
Principal Business Address (Line 2)
textUse this line for suite, unit, or floor number if applicable; otherwise, it can be left blank.
COMMON MISTAKE: Incorrectly placing the city, state, and ZIP code here instead of in the designated fields on the form, which scrambles the address parsing.
Representative Mailing Address (Line 1)
textEnter the street address or P.O. Box where official correspondence for the authorized representative should be sent.
COMMON MISTAKE: Duplicating the principal business address here if the mailing address is different, which can cause processing delays for notices.

textOwner 1 Name and Address
textList the full legal name and complete residential or business address of the first owner, partner, or corporate member.
COMMON MISTAKE: Omitting the address for an individual owner or listing only the business name for a corporate owner, violating the disclosure requirements in ORS 648.005.

Top 5 Trade Name/DBA Registration Mistakes
1. Submitting an Already-Taken or Confusingly Similar Name
Filing for a name that is identical or too similar to an existing registered business or trademark in Oregon causes immediate rejection. Based on ApronPrep's analysis, this is the most frequent cause of denial, often adding 2-3 weeks to your timeline as you must restart the process. Avoid this by conducting a thorough search of the Oregon Secretary of State's business name database *and* checking the USPTO trademark database before filing.
2. Incomplete or Incorrect Entity Information
Listing your personal name instead of the exact, full legal name of your business entity (e.g., 'John Smith' instead of 'Smith Restaurant Group LLC') is a common error that voids the filing. This discrepancy can cause legal and banking problems, as the DBA will not properly connect to your LLC or corporation. Always enter your entity's name exactly as it appears on your state-issued Articles of Organization or Incorporation.
3. Using a Restricted or Misleading Name
Proposing a name that implies a different business structure (like using 'Inc.' when you're a sole proprietor) or includes restricted words (e.g., 'Bank,' 'Trust,' 'University') without proper authorization leads to rejection. This mistake is often due to not reviewing the Oregon naming rules, causing a 1-2 week delay for correction. Ensure your trade name accurately reflects your business type and avoids legally protected terms.

Conduct a Name Availability Search
Before filling out any forms, check if your desired trade name is available in Oregon. Use the Oregon Secretary of State's online business name search tool. Your DBA must be distinguishable from all other registered business names in the state. A common reason for rejection is picking a name that is too similar to an existing one. Have at least 2-3 alternative names ready in case your first choice is taken.
Prepare Your Application Materials
Gather the required information for the state's Assumed Business Name form. You'll need the legal name and address of the business entity or sole proprietor registering the DBA, the exact trade name you're registering, and a description of the business activities. If you are a corporation or LLC, have your business registration number handy. ApronPrep can auto-fill this data from your business profile to prevent mismatches.
Complete and Submit the Assumed Business Name Registration
File the registration online through the Oregon Secretary of State's Corporation Division website, which is the fastest method. The form itself has approximately 15 fields. You must pay the $50 government filing fee via credit card or pre-established account during the online submission. Paper filings by mail are still accepted but can add 1-2 weeks to the initial processing time.

See All RequirementsProcessing times vary significantly, from a few days to several weeks, depending on the filing method and the current volume at the Oregon Secretary of State's office. Filings submitted online are typically processed faster than paper applications mailed to the state corporation division. For the most current timeline, check the processing times posted on the Oregon Secretary of State’s website or contact their office directly.
The government filing fee to register a trade name (also called an Assumed Business Name) with the State of Oregon is $50. This is a state-level fee paid to the Oregon Secretary of State, as outlined in their official fee schedule. This registration is separate from obtaining your official City Business License/Registration from the City of Portland's Revenue Division. Not legal advice — verify with the Oregon Secretary of State.
A trade name registration itself is not 'transferred.' If your business entity (like an LLC or corporation) moves, you must file an amendment to update its principal office address with the Oregon Secretary of State. If the business structure is changing or you are operating under a new legal entity, you must file a new Assumed Business Name registration. For changes related to your physical premises, you may also need a new Certificate of Occupancy from the City of Portland.
An Oregon Assumed Business Name registration does not expire and does not require periodic renewal. It remains in effect until you formally withdraw it or until the underlying business entity (like your LLC or corporation) is dissolved or administratively dissolved by the state. You must, however, keep the registration current by amending it with the Oregon Secretary of State if the business name or the legal name of the registrant changes.
There is no physical inspection conducted by the state for a trade name (DBA) registration. The process is purely administrative, involving a review of your application by the Oregon Secretary of State's office to ensure the proposed business name is not deceptively similar to an already registered name in their database. The 'inspection' risk lies in ensuring your chosen name complies with state naming rules and does not infringe on existing trademarks.
