Naming Your Washington LLC

Whether you’re searching for the right Washington business name or registering your LLC with the Secretary of State, we can help. We’ve got all the information you need on a business entity search, LLC naming rules, fictitious names and registering your business.

Washington Secretary of State Business Search

You should start naming your business by completing a business entity search with the Secretary of State. They have a helpful tool on their website that lets you search the register of WA LLCs and corporations to see if someone already has your desired business name.

If the business name is already used, that means it’s not available and you won’t be able to register it. Try searching for a different business name instead.

Washington “Doing Business As” (DBA) and Trade Names

You might choose to do business under a different name from your legal LLC name. In Washington, doing business under a different name is known as a “Trade” or “Doing Business As (DBA)” name. You might choose to use a different name from your formal LLC name for a variety of reasons.

For example, your LLC might be called Washington Real Estate Waterside Holding Company LLC and you have a brand called “Seattle Lakefront Properties.” You should file a trade name to let the Washington Secretary of State know. In Washington, you do that through a Business License Application form, or you can have Incfile do it on your behalf through our Assumed Business Name service.
