What a contractor page shows
- Registration: business name, license number, UBI, license type and specialty, status, effective and expiration dates, address and phone.
- Bond: the surety company, bond number, amount and dates, or "no current bond located".
- Insurance: the liability carrier, policy number, coverage amount and dates.
- Principals: the people the state lists for the business.
- Complaints: Attorney General consumer complaint records matched to the business, with a count and dates.
- Record history: what changed in the registration, bond and insurance records since this site began keeping nightly copies. The state's lookup shows the current status only.
Every section names its dataset and the date it was last synced.
How it works
- Search. Type the business name, the license number or the UBI from a bid, a card or a truck. One match opens the page; several show a list to choose from.
- Read the records. Each section is a state record with its source and sync date. The "Current verification" list at the top is produced by fixed rules from those records; it is not a score.
- Confirm with the state. Each page links to the same license on L&I'sVerify a Contractor page, where the state's own record can be read directly before you sign anything.
By state
- Washington
76,509 active registrations, by city and trade. Records from the Department of Labor & Industries and the Attorney General.
How this site works
- Searching is free and needs no account. Nothing is held back behind a sign-up.
- There are no ratings, scores or rankings. Every statement on a contractor page is a record, with its source and date, or a line produced by a fixed rule from those records.
- There are no lead forms. The site does not ask for a homeowner's name or number and has nothing to sell to anyone.
- No record is changed, hidden or removed for payment or on request. A record that is wrong is corrected at the agency that publishes it, and the page follows.
- A contractor who claims a page adds their own words in a block labeled as theirs. The state's records stay as published.
- Paid placement, when offered, is labeled "Paid placement" and changes nothing else: not the records, not the status shown, not search results or the order of any list.
What we check explains the sources and the rules in full.
Are you a contractor?
Every registered Washington contractor already has a page here, built from the state's records. Claiming it is free: find your page by license number, follow the "Claim this profile" link, and send a document that shows the license number. Once a person has checked it against the state record, you can add a logo, website, description, service area, hours and contact details, and respond under any record section. The records themselves never change.
Featured placement on your city page, labeled as paid, is not offered yet. It will be announced to claimed businesses when it is.
Common questions
- Is this the state's official contractor lookup?
- No. Contractor History is an independent site. The records come from the open datasets Washington State publishes: the Department of Labor & Industries' contractor registration, bond, insurance and principal data, and the Attorney General's consumer complaint data. The state's own tool is L&I's Verify a Contractor page, and every contractor page here links to the same license there.
- Is it free?
- Yes. Searching and reading any contractor page is free and needs no account. A contractor can claim their own page for free. Paid placement, when offered, is labeled as paid and changes nothing about the records.
- How current is the information?
- The state's datasets are copied every night, and each section of a contractor page shows the date its dataset was last synced. The state updates its datasets on its own schedule, so a change made at L&I can take a day or two to appear.
- What does a page show that the state's tool does not?
- Record history. The state's lookup shows a contractor's current status only. This site keeps what the records said each night, so a page can show what changed and when: a status that moved from active to suspended, a bond that was canceled, a change of insurance carrier. A page also shows Attorney General complaint records matched to the business by name and city, with a count and dates, on the same page as the license, bond and insurance records.
- What does "Verified by the business" mean?
- That the person who added information to the page sent a document showing the license number and a person checked it against the state record. It says nothing about the quality of their work and is not a rating or a recommendation.
- Can a contractor remove a complaint or change a record?
- No. A contractor who claims a page can add their own words in a block labeled as theirs, and can respond under a record section, but cannot change, hide or remove any government record. A record that is wrong is corrected at the agency that publishes it, and the page follows.
- What is a UBI?
- The Unified Business Identifier, a nine-digit number Washington State assigns to a business. One business can hold more than one contractor license under the same UBI, and a contractor page lists the other licenses registered under its UBI.
- Which states are covered?
- Washington State. Every registered Washington contractor has a page.
