Filing a DBA in Delaware is Easy

Step 1. Do a Delaware Trade Name Search With the State

Your Delaware trade name must be unique and must also meet Delaware’s business name requirements.

Before you file, you will need to search the state’s records to make sure your exact name isn’t already taken. You will also need to consider any state naming rules.

Your Delaware trade name should NOT include:

  • Any business entity suffix, such as LLC, Incorporated, Corp, etc., unless the business is actually an LLC, corporation, etc.
  • The word “bank,” or any variation unless the company is authorized as a bank by the state. However, the word “bank,” or any variation, can be used if the context clearly doesn’t refer to a banking business or mislead the public about the nature of the business.

Step 2: Register Your Delaware DBA

Delaware trade names are filed with the county or counties where your company does business.

A DBA does not offer any protection for your personal assets in the event that your business is sued. For more information on setting up a limited liability company, visit our How to Form an LLC page and select your state.

Filing a DBA With the County Clerk

DBA regulations are managed by the state of Delaware which means the steps for getting a DBA are similar from county to county.

Each of the three counties in Delaware use the same trade name registration form.

How to File a Delaware DBA

Delaware trade names must be registered in each county where your company does business. You can do this by submitting the Registration of Trade, Business & Fictitious Name Certificate with the County Clerk’s office by mail or in-person. The certificates must be notarized.

Reminder: Delaware requires that you check their trade name records before filing to make sure your name isn’t already taken.

DBA Delaware FAQ

How many DBAs can I have?

You can have as many DBAs as you can afford to create and are able to keep track of. Each one comes with additional incremental expenses and paperwork, meaning more is not necessarily better.

Can a DBA get an EIN or Tax ID?

DBAs aren’t required to have a separate EIN because DBAs aren’t a business entity. The business entity that the DBA is under would have an EIN if an EIN is required.

To learn more about EINs and when you need one for your business, read our What is an EIN guide.

Can a DBA become an LLC?

No. An LLC is a business entity, while a DBA is just a name for a business.

Sole proprietorships are often confused with DBAs, but they are not the same: a sole proprietorship is a business entity, therefore it can choose to become an LLC.

To learn how to form an LLC, visit our Form an LLC state guides.

Can a DBA have Inc. in the name?

A DBA can only have Inc. in the name if the business entity the DBA is attached to is a corporation.

How do I set up a DBA for a rental property?

Holding a rental property in your name and with a DBA will not afford you any protection. The best option is to form an LLC to protect your personal assets in the event of an issue with the rental property. In any case, it is always best to consult an attorney.

When would it be good to get a DBA vs a legal name change?

Getting a DBA is often a better choice than changing your business’s legal name. If you want to rebrand your company or focus on another line of business, filing for a DBA is a simpler process than filing for a legal name change.

Is my DBA protected from being used in other places?

Some state-level laws prevent DBAs that are too similar to existing ones from being used, but this varies from state to state. It is possible to trademark a DBA, which would offer stronger protection across state lines.
