The register, joined

Everything on this site is free to read. What is sold is the work of joining five tables, separating two contradictory status fields, and computing the links between businesses.

The pages of this site are free and will stay free : an official fact belongs to no one. What is sold here is the compilation work — extracting Washington State L&I's contractor registration data, reconciling it, dating it, and delivering it in a usable form.

What is actually added

L&I publishes five tables. Joining them is the easy part — the contractorlicensenumber matches perfectly across all of them, which is rare enough to be worth saying. What is not in any of the five:

The flow is the product

L&I refreshes these tables every day and publishes no change log. A snapshot tells you today; only a sequence tells you that a subcontractor lapsed, got suspended, or let a policy expire. We keep every collection from 2026-08-20 on and deliver the differences.

The 6 fields marked ⚠️ do not exist in the source : we add them — a join, a normalisation, or a reconstructed history. That is the part a buyer cannot reproduce by downloading the official file.
