Washington Business Entity Search: A Complete Guide to the Secretary of State

How many companies are on the Washington register?

Three questions, three answers. How many are registered? The Secretary of State publishes no standing status-total at a fixed URL, and Washington is unusual in that the online system isn’t even a complete history: entities inactive for more than ten years are purged to the State Archives, so any live count understates the entities that have ever existed. How many file? The federal formation series recorded 62,371 new business applications in Washington across the first half of 2026 — down 28.2% year over year, a cooling that ranks the state 15th of 51 jurisdictions by application volume. How many actually operate? The best official answer is federal: the SBA’s 2025 Washington profile, built on Census data, counts 695,695 small businesses — 99.5% of all Washington businesses — employing 1.5 million people, with establishment churn of 24,701 openings against 14,578 closings in the most recent measured year, a net gain of 10,123 that is among the healthiest in the country.

The layers of Washington company data

Washington company data runs through one register with unusually deep people disclosure, a cross-agency identifier that ties four state agencies together, the annual-report layer, and the federal overlay. Four sources matter.

The two-agency split is the structural fact to hold onto: the Secretary of State’s CCFS holds formation, status and governors; the Department of Revenue’s Business Licensing Service holds the state business licence, endorsements and — critically — sole proprietors, who never appear in CCFS at all. A complete Washington picture means checking both records under the same UBI.

What the Washington search actually gives you

Washington’s free tier is people-deep — the rare US register that names members and lets you search by officer:

Open a record in the CCFS search and the fields that matter are these:

• Identity, on the UBI. Legal name, the nine-digit Unified Business Identifier, entity type, status and formation date. The UBI is the key — and the join to the entity’s records at Revenue, Employment Security and Labor & Industries.
• Governors — the deep layer. The annual report names the entity’s governors, and Washington’s definition is broad: officers, directors and managers, and for an LLC its members. This is closer to ownership disclosure than almost any US register offers — though it names the people, not their percentages.
• The people-search keys. The Advanced Business Search lets you search by governing person and by registered agent — reverse lookups that turn the register into a tool for mapping a person’s or an agent’s Washington footprint.
• The registered agent and office. Every entity must maintain a Washington registered agent; the agent’s authority even survives administrative dissolution. The principal office sits alongside.
• The filing history. Formation documents, amendments, agent changes and every annual report — viewable free, no login.
• What it still won’t show — and where it hides. Ownership percentages, sole proprietors (they’re at Revenue, not the SOS), the licence-and-standing check (also Revenue), and any financials. One UBI, but two agencies to check.

For multi-state work, Washington pairs naturally with North Carolina — the other register you can search by officer — plus Delaware, the register Costco left, and the privacy-trio contrast of Nevada and Wyoming.

Every Washington company-data dataset, mapped

Across the CCFS search, the annual-report layer and the federal overlay, twelve datasets matter for KYB. Washington’s mix is people-deep and free — with the ownership cap table and the second agency the two things it holds back.

Exactly what data is free, paid & withheld

The free tier is unusually deep — governors and two people-keys; the paid tier is the report and certificates; the wall is ownership stakes and the records that live at Revenue.

Dataset-by-dataset summary

The same data, viewed by source rather than access tier:

Seven free, two paid, three not in CCFS. Washington’s free tier is among the richest in the country — two people-keys, a cross-agency identifier, and governors that include members. What it withholds is the arithmetic of ownership and the records that sit at the Department of Revenue. Sources: Washington Secretary of State; RCW 23.95; SEC EDGAR (verified July 2026).

The Washington company identifiers

Washington’s identifier set is anchored on the UBI — and the UBI is unusual in that it’s genuinely cross-agency:

For production Washington KYB: resolve on the UBI; use the officer- and agent-search keys for reverse lookups; read the annual report for the current governors, including members; check the Department of Revenue record under the same UBI for licence and standing; pull the free filing history; and cross-check listed groups against EDGAR by CIK.

Worked example: the giant that came home

Washington charters one of the country’s biggest retailers — and its story inverts the usual Delaware narrative:

The contrast case is Washington’s other giant — the one that left:

And the register’s everyday product — the Washington LLC:

The ownership story — members named, stakes still hidden

Washington reaches further toward ownership than almost any US register — but it’s worth being precise about exactly how far, because it stops before the finish line.

Members, named. Washington’s statute (RCW 23.95.105) defines an entity’s governors to include, for an LLC, its members — and the annual report names them. That is genuinely rare: most US registers name managers and officers (operators) and never touch ownership at all. Washington names the members, so the people who own the company appear on the public record alongside those who run it. For due diligence on who is behind a Washington LLC, this is among the best free disclosure in the country.

Stakes, hidden. But naming members is not a cap table. The report lists the people; it does not quantify their ownership percentages, and it does not distinguish a 1% member from a 99% one. A passive investor and a controlling owner can appear identically. So Washington answers “who are the members?” far better than most states — and still leaves “who controls this company?” to inference. The register reaches toward ownership; it doesn’t resolve it.

The federal gap, reopened. The Corporate Transparency Act was meant to close that last gap with a federal beneficial-ownership registry recording ownership percentages and control. Then FinCEN reversed in March 2025, exempting all US-formed entities. So Washington’s member-naming report is now, for many private entities, the deepest public ownership signal that exists — better than most states offer, but still short of the percentages a true beneficial-ownership register would carry. For listed groups EDGAR fills it; for the private majority, the counterparty or commercial intelligence does.

Washington’s economy — what the register sits under

One of the ten largest state economies, an enterprise-formation magnet with no personal income tax — the scale behind the register:

API and bulk data feeds — the two real paths

Washington offers no public developer API for the register, and its official access story is the CCFS portal. Two paths matter.

Path 1 — The CCFS search and its people-keys

Free lookups by name, UBI, officer/governing person and registered agent, with the full filing history and documents viewable without a login, and certified copies orderable through the same portal. The Advanced Business Search makes this more capable than most state portals for manual reverse lookups. The constraints: no bulk export, no programmatic API, no ownership percentages, and the two-agency split — the licence and standing record lives at the Department of Revenue, not CCFS.

Path 2 — commercial multi-jurisdiction APIs and bulk feeds

For teams needing Washington alongside the other 49 states — and needing the governor-and-officer layer as structured, queryable data rather than one-record-at-a-time portal lookups — commercial providers deliver the register joined to cross-state registrations, the federal layer and screening through one API. Zephira’s Washington data is sourced directly from the official register with Data Provenance attribution on every field, joined to all 50 US states, Canada, Mexico, and 100+ other jurisdictions on a single data model — with bulk delivery via S3 or SFTP for batch enrichment and offline analytics.

Washington entity types — what each one means for KYB

Washington’s menu is the standard set plus a couple of distinctive forms, each grounded in the Uniform Business Organizations Code (RCW 23.95) or its sister titles — with the annual report the near-universal common denominator:

When a Washington entity lapses — delinquency, then dissolution

Washington starts with a fee and escalates on a statutory clock toward ending the entity. The stages, per RCW 23.95:

The reading discipline: in Washington, the status label and the formation month together tell the story. A Delinquent flag is the first warning; the anniversary-month deadline means you must know the formation month to judge how overdue a report really is; and because reinstatement is possible for five years, a dissolved Washington entity isn’t necessarily gone — but it has lost its good standing until it cures.

What the Washington register doesn’t tell you

Even one of America’s deepest registers keeps five blind spots worth naming:

• Ownership percentages. Washington names members, which is rare — but not their stakes. The report can’t distinguish a controlling owner from a minority one, so it tells you the people without the arithmetic of control.
• The second agency. The CCFS search sees only the Secretary of State’s half. The state business licence, endorsements and sole proprietors live at the Department of Revenue under the same UBI — so a clean CCFS record isn’t a complete picture, and a sole proprietor won’t appear at all.
• The purged past. Entities inactive for more than ten years drop out of the online system to the State Archives. A company that dissolved twelve years ago won’t surface in a routine CCFS search — the online register is a working set, not a full history.
• Financials. No accounts are filed with the register, and Revenue records are confidential. For the private majority, the register proves existence and names governors — not revenue, size or solvency.
• Trading reality. Registration and a current $70 report prove the entity exists and is attending to its filings — not that it operates, holds an active licence, or occupies the address on file. Holding a UBI is not the same as good standing.

The ownership signal, the deep register and sanctions

Washington’s member disclosure helps with screening — but doesn’t complete it. Naming members is closer to ownership than most registers get, yet without percentages you can’t confirm whether a sanctioned party holds a controlling stake. OFAC’s 50 Percent Rule blocks any entity owned in aggregate 50% or more by sanctioned parties, listed or not — and a named member could hold anywhere from a token share to majority control. So even Washington’s deep people data requires the screening layer the register can’t provide: names checked against the SDN and consolidated lists, ownership resolved to percentages past the member level, and continuous monitoring rather than point-in-time checks — on every counterparty, however open its Washington record looks. See free company verification for where that workflow starts.

How to verify a Washington company, step by step

The practical sequence, using the register’s strengths:

1. Find the record. Search ccfs.sos.wa.gov by name — use “Starts With” or “Contains,” drop entity designators and pluralization — and capture the UBI. Or start from a person, using the governing-person or agent search in the Advanced Business Search.
2. Read the status — and the formation month. Confirm the entity isn’t Delinquent or administratively dissolved, and note the formation month so you can judge how current the annual report really is.
3. Pull the latest annual report. Extract the governors — including members for an LLC — the registered agent and the offices. This is Washington’s deep layer; use it, and cross-check listed groups against EDGAR.
4. Check the other agency. Look up the same UBI at the Department of Revenue for the business licence and standing — CCFS alone won’t tell you whether the entity can lawfully operate.
5. Run the reverse lookups. Use the officer and agent keys to see what else a person governs or an agent represents — the capability that sets Washington apart.
6. Check the archives if needed. For an entity inactive more than ten years, the Washington State Archives Digital Archives — not CCFS — is where the record now lives.
7. Screen separately. Sanctions, watchlists and ownership percentages live outside the register entirely — run them on every counterparty regardless of standing.

Where Zephira sources Washington data from — directly

Zephira’s Washington coverage is sourced directly from the official register — the Secretary of State’s CCFS records, filing histories and the governors named on every annual report — not scraped from intermediaries or bought from resellers. Every field carries Data Provenance attribution: the source register, the filing it came from, and the date it was attested. The governor and officer data Washington exposes becomes structured, cross-state entity resolution: a member in Seattle resolves to the other entities they govern in other states, an agent’s book resolves across jurisdictions, and the state layer joins the federal layer (EDGAR, sanctions lists) and 100+ international registers on one data model.

The distinction that matters for a data team isn’t whether the data is public — the CCFS register is free and open — but how it’s shaped for use. Below is a detailed, line-by-line comparison of the official Washington source, the Secretary of State’s Corporations & Charities Filing System (CCFS), against a consolidated data layer built directly on top of it. The government register is always the source of truth; the second column is what changes when that same record is sourced, structured and joined at scale.

Identity, scope & coverage

Access, delivery & format

People, ownership & the record

Integration, monitoring & compliance

Read the four tables together and the division of labour is clear. CCFS is, and remains, the source of truth — for a single Washington lookup it is free, authoritative and complete on its own terms. The consolidated layer earns its place only where the register’s boundaries bite: another state, the federal layer, a sanctions list, a person’s footprint beyond Washington, a lapsed entity past the ten-year purge, or the same query run ten thousand times in a pipeline. Every value in the Zephira column traces back to CCFS or the other official registers it joins — nothing there replaces the government record, and nothing asserts data the register doesn’t hold.

Recent and ongoing developments

Washington’s register is stable but modernising — the watch items:

• The CCFS platform. The current Corporations & Charities Filing System replaced the older corporations.wa.gov system, which no longer resolves — much of the web still links to the retired address. Always start at ccfs.sos.wa.gov.
• March 2025 — the federal reversal. FinCEN’s interim final rule exempts US-formed entities from beneficial-ownership reporting, leaving Washington’s member-naming report as one of the deepest public ownership signals most WA entities now have — though still short of ownership percentages.
• The formation cooling. New-business applications ran 28.2% below the prior year in the first half of 2026 — a real slowdown worth watching as a demand signal, even as the operating base kept growing.
• Watch items. Whether Washington extends its governing-person search or enriches the member disclosure toward stakes; and whether the ten-year online purge window changes as the archives digitise further.

Washington registry activity — verified primary-source statistics

Formation flow first — and Washington’s most honest recent number is a decline. New-business applications in the first half of 2026 ran well below the same period a year earlier:

The cooling in formations sits atop a still-growing operating base — 24,701 establishments opened against 14,578 closed in the most recent measured year, a net gain of 10,123. Now the cross-state comparison this register invites — what a decade of staying registered costs an LLC, at current fees:
