Yes. The Department of Licensing maintains the database that contains all trade names registered with Washington State. Visit the Department of Licensing's website to search for trade names or call (360) 664-1400.
If the trade name is not found, there is no guarantee that the name is not being used – only that it is not registered with Washington State. The Department of Licensing also provides information regarding corporations, persons conducting business under a trade name, or verification of an existing business.
The Business Records Database is provided as a consumer protection program. It should not be relied on for determining whether a trade name is registered.
