How to search
Start with company search and jurisdictionCode: "us-wa". Pass the name as companyName, a registration number as companyNumber, or both to narrow the result. Here companyNumber is read as ubi.
Fields
To say exactly what you mean, send an advancedQuery instead. Washington (US) understands these fields:
| Field | What it does |
|---|---|
name | Business name to search for. |
ubi | Washington UBI number, 9 digits (e.g. 600 413 485 or 600413485). |
Examples
{ "jurisdictionCode": "us-wa", "advancedQuery": { "ubi": "600 413 485" }}Company identifiers
Search by passing the registration number as companyNumber — it is matched against the schemes this register can search on, so you do not name the scheme yourself. Not every scheme below is searchable; the rest label the values returned in a company’s identifiers.
| Identifier | Appears as | Format |
|---|---|---|
| WA UBI Number Washington Unified Business Identifier (UBI) — a 9-digit statewide business number issued by the Department of Revenue and shared across WA agencies, displayed space-grouped by the registry (e.g. 600 413 485). It is the public identifier for a Washington entity; the registry accepts it spaced or unspaced. | us_wa_ubi | ^[0-9]{3} ?[0-9]{3} ?[0-9]{3}$ |
Documents you can order
| Document | Status |
|---|---|
| US-WA Document Document retrieval for Washington entities from the Washington Secretary of State.

Pre-2000 filings are scanned images without a text layer. | Live |
These are filings whose availability differs per company: call list documents first and order the ID it returns.
Local notes
Gotchas
| Trap | What happens |
|---|---|
| EIN is usually absent | A federal EIN is present on only a minority of Washington entities, mostly nonprofits — its absence on a for-profit corporation or LLC is normal and not a sign of missing data. |
| Activity text is free text | The business-activity text for a Washington entity is free text — the register's own category label plus the filer's own description — not a code from a standardized scheme such as NAICS. Don't map or join it against an external NAICS taxonomy expecting it to match. |
| Some filings have no document | Not every filing in a Washington entity's history has a retrievable document behind it. Office Correction filings are the clearest known case: the filing appears in the history, but requesting its document fails. |
Glossary
| Term | Meaning |
|---|---|
Governor | Washington's Secretary of State does not record officer or director titles. Every person with governing authority over an entity is listed under a single role, "Governor" (RCW 23.95) — treat it as the functional equivalent of a director or manager in this data. |
