What you get with a Washington lookup
- Washington SOS entity record — name, status, entity type, formation date, registered agent + address, principal office, and officers/managers where the state exposes them.
- USDOT / FMCSA carrier verification — for trucking deals, we pull the carrier's authority status, MC#, fleet size, MCS-150 history, and BASIC scores. Auto-matched to the SOS legal name when applicable.
- OFAC SDN screening — every search runs the company name against the Treasury sanctions list. Clear-result PDFs are signed.
- DBA / Fictitious Name registries — surfaces the county/town clerk where this entity would file a DBA in Washington, plus the statewide registry when one exists.
- One merged PDF — cover sheet + SOS record + USDOT snapshot + supporting docs, all in a credit-file-ready packet.
How Washington files business entities
Washington files corporations and LLCs at the SOS (Corporations and Charities Filing System), but TRADE NAMES file with the Department of Revenue — a rare two-agency split that catches most credit processors off guard. WA also publishes L&I Contractor Licenses and DOL Transportation Licenses as open data on data.wa.gov.

How DBAs work in Washington
Washington Trade Names file at the Department of Revenue's Business Licensing Service — not the Secretary of State. The same DOR portal handles statewide business licensing, so verifying a WA trade name requires a DOR lookup, not an SOS lookup. The SOS Corporations and Charities database covers entity-level filings only.
Credit-underwriting gotchas in Washington
Washington LLCs pay a $60 annual report fee due on the formation anniversary — the report is technically called an 'Annual Report' (since 2019; previously 'Annual License Renewal'). Missed reports trigger 'Inactive' status after 120 days delinquent. Washington has no state income tax but DOES levy a Business and Occupation (B&O) tax on gross receipts — a common surprise for out-of-state operators. The SOS portal is Incapsula-gated.

Filing fees: $200 online ($180 paper) LLC formation fee + $60 annual report
Officer visibility: Officers, governors (Washington's term for LLC managers), and registered agents are visible on the public CCFS detail page. Trade Name data lives at the DOR, not the SOS — be sure to check both for a complete picture.
