Delaware DBA — Frequently Asked Questions
What is a DBA?
A DBA — commonly called a DBA (Doing Business As) — is a registration that lets you operate a business under a name different from your legal name. In Delaware, this filing is officially known as a DBA registration. It's required if you want to use a business name that isn't your personal legal name (for sole proprietors and partnerships) or your entity's registered name (for LLCs and corporations).
Where do I file a DBA in Delaware?
In Delaware, DBA filings are handled at the state level through the Delaware Secretary of State. You can learn more at Delaware Secretary of State.
How much does it cost to file a DBA in Delaware?

How long does it take to get a DBA in Delaware?
Most DBA filings in Delaware are processed within 5-10 business days after submission. Processing times vary depending on state processing volumes.
Do I need a DBA if I have an LLC?
It depends. If you want your LLC to operate under a name different from its registered entity name, then yes — you need a DBA filing. If you plan to do business only under your LLC's registered name, you do not need a separate DBA.
Does a DBA protect my business name?
A DBA registration gives you the right to use the name in your filing jurisdiction, but it does not provide the same level of protection as a trademark. For stronger name protection, consider filing a federal trademark with the USPTO.
