What is a DBA in business? DBA stands for “doing business as.” It is a registered name that a person or company uses to operate instead of its official legal name. A DBA is also called an assumed name, fictitious business name or trade name. It does not create a separate company or give you liability protection.
What does DBA mean in business?
Every business has a legal name. For a sole proprietor, that’s usually the owner’s own name, such as “Maria Lopez.” For an LLC or corporation, it’s the exact name on the formation documents, such as “Lopez Ventures LLC.”
If you want to sell under a different name, like “Sunrise Bakery,” many states require you to register that name as a DBA. You will then often see it written as “Maria Lopez DBA Sunrise Bakery.”
DBAs are filed with your state, county or city, depending on where you are. The process is usually a short form and a fee. Some places also require you to publish a notice in a local newspaper.
Who needs a DBA?
- Sole proprietors and partnerships using any name other than the owners’ legal names
- LLCs and corporations operating a brand that differs from their registered legal name
- Businesses with multiple brands, such as one LLC running two shops under different names
Banks commonly ask for proof of a DBA before opening an account in the business name, and payment platforms may too.
Examples of DBA in emails and documents
Invoice: “Bill from: Daniel Kim DBA Kim Home Repairs”
Bank email: “To open the account under your trade name, please bring a copy of your DBA certificate.”
Contract: “This agreement is between Greenleaf Holdings LLC, doing business as Greenleaf Coffee, and…”
Owner to accountant: “Do I need to file a new DBA if I open a second location with a different name?”
DBA vs LLC vs trademark
| DBA | LLC | Trademark | |
|---|---|---|---|
| What it is | A registered business name | A legal business entity | Legal protection for a brand |
| Liability protection | No | Generally yes | No |
| Separate tax entity | No | Can be, depending on election | No |
| Stops others using the name | Usually no | Only within state entity records | Yes, within its scope |
| Where filed | State, county or city | State | USPTO (federal) or state |
A DBA is not a substitute for an LLC. If you want personal liability protection, you need a business entity. You can have both: an LLC that also registers a DBA.
How to get and use a DBA correctly
- Search the name first. Check your state’s business database and the USPTO trademark search to avoid conflicts.
- Find where to file. Your state’s Secretary of State or county clerk website will explain the process.
- File the form and pay the fee. Fees and renewal periods vary by location.
- Complete any publication requirement. Some states require a newspaper notice.
- Use it consistently. Put the DBA on signs, invoices and your bank account, and keep the legal name on contracts.
- Renew on time. Many DBAs expire after a set number of years.

Only if your LLC does business under a name other than its exact registered name. For example, “Smith Ventures LLC” operating as “Smith’s Garden Shop” usually needs a DBA.
Where do I file a DBA?
It depends on your state. DBAs are filed with the state, the county or sometimes the city. Your state’s Secretary of State website is a good starting point.

No. Registering a DBA usually doesn’t stop others from using the same name. A trademark gives legal protection for a brand name or logo.
