Washington LLC Name Search & Naming Rules (2026)
Your Washington LLC name has to clear the Secretary of State's database before you can file. Here's how to search it free and the naming rules that trip people up.
Search availability free with the Washington Secretary of State's Corporations & Charities Filing System (CCFS). Your name must be distinguishable from every existing Washington entity and contain "Limited Liability Company," "LLC," or "L.L.C." Washington does not require a separate reservation fee to claim your name — it's claimed automatically when your Certificate of Formation is approved. A standalone name reservation is available for a modest fee if you're not ready to file yet.

Washington LLC Naming Rules
- Required designator: the name must contain "Limited Liability Company" or an abbreviation — "LLC" or "L.L.C."
- Distinguishable on the record: it can't match or closely shadow any entity registered with the Secretary of State.
- Restricted words: terms implying banking, insurance, or government affiliation require proper authorization.
Check the domain before you commit: at $200 to file online, a name mistake isn't the expensive part of forming in Washington — but a branding one still is. Before you fall for a name, confirm the .com (or a clean variant) is free and grab the matching social handles. The state check takes a minute; whether your real brand is available online is what actually matters for your long-term business.

Check close variants
Minor spelling, spacing, or punctuation differences don't reliably make a name distinguishable — when in doubt, contact the Secretary of State to confirm.
File once your search is clean
Proceed directly to the Certificate of Formation — your name is claimed at no extra cost.
The Name Reservation
If you're not ready to file yet, Washington offers a standalone name reservation for a modest fee through the Secretary of State, holding your chosen name before you submit your Certificate of Formation. But since claiming the name is free when it's part of your actual Certificate filing, the standalone reservation only makes sense for founders with a genuine multi-week or multi-month delay before they're ready to form.
Ahmad Adil's Take: Washington's naming process is genuinely simple, and the fact that claiming your name is free when bundled with your Certificate filing is a real convenience. My advice on names is the same everywhere: don't skip the domain check just because the state process is simple. A $200 formation cost is nothing compared to redoing your branding after you've already built a following around a name that turns out not to work online.
