Washington Business Name Search
Two checks stand between you and a name you can actually use: the state register, and everything outside it — the domain and the social handles. Do both here.
Step 1: Search the Washington Secretary of State
Businesses and charities in the Corporations and Charities Filing System (CCFS), searchable by name or UBI number.
Open the Washington registerWashington issues a UBI number that ties your registration to state tax accounts. Confirm the name is clear in CCFS before you apply for your business licence, not after.
Step 2: Check the domain and social handles
A clear state register is only half the answer. If the .com is gone or the handle is taken on Instagram and TikTok, customers will end up at someone else's brand.
Check your name across domains and every major social platform:
Step 3: The name is clear — now claim it
- Register the domain first. It's the cheapest and most contested piece. Grab it on Namecheap before you start the state filing — registration takes days, a domain takes minutes.
- File with the Washington Secretary of State. Register your LLC or corporation under the name you just cleared.
- Claim the social handleson every platform, including the ones you don't plan to use yet.
- Put the name to work.If you're selling online, start the store on Shopify and point your new domain at it.

Washington business name ideasWashington Business Name Questions
How do I check if a business name is already taken in Washington?
Search the Washington Secretary of State register. Businesses and charities in the Corporations and Charities Filing System (CCFS), searchable by name or UBI number. If no active entity holds the name, it is generally available to register in Washington.
Does a clear Washington register mean I own the name?
No. A state register only clears the name for filing within Washington. It does not grant trademark rights, and it does not stop someone in another state from using the same name. For nationwide rights you need a federal trademark.
Should I check the domain before or after I register the business?
Before. Domains and social handles are first-come, first-served and cost a few dollars, while changing your registered business name after filing means paperwork and fees. Check the name across the register, the .com and the social platforms in one pass, then file.
What is Washington's naming rule for new entities?
Washington issues a UBI number that ties your registration to state tax accounts. Confirm the name is clear in CCFS before you apply for your business licence, not after.
