Automated L&I License Tracking & Expiration Alerts
Checking a sub's L&I registration by hand? TrackMyVendor monitors every Washington contractor license and registration daily and alerts you the moment anything changes — before it becomes a problem on your job site.
Most Washington GCs using TrackMyVendor discover their bigger headache isn't licenses — it's chasing COI renewals and W-9s. You can track all three in one place.

A Washington L&I registration can go from Active to Suspended overnight — triggered by a surety bond lapse or workers' compensation cancellation, with no notice to you whatsoever. A sub whose registration was Active yesterday can be Suspended this morning because their bond renewed late.
TrackMyVendor checks every tracked registration daily and alerts you the moment the status changes — so you're not relying on a one-time lookup done at onboarding.
Washington contractor license requirements
Before hiring contractors in Washington, you need to verify they maintain proper credentials with the Washington State Department of Labor & Industries (L&I). Washington contractors are often required to have:
- A valid L&I contractor registration for general construction work (required for projects over $500 in labor and materials)
- Active insurance coverage (Certificate of Insurance) and a surety bond filed with L&I
- Workers' compensation coverage through L&I (if they have employees)
- A separate specialty license (electrical, plumbing, elevator) for trades regulated beyond the general registration
- Tax documentation (such as W-9 forms)
Washington L&I contractor registration types
Washington uses "registrations" for general contractors and "licenses" for specialty trades — both issued by L&I. TrackMyVendor tracks all of them at the company level.
| Type | L&I Code | Trades / Scope |
|---|---|---|
| Construction Contractor Registration | CC | General building and construction; required for projects over $500 in labor and materials |
| Electrical Contractor License | EC | Electrical work on buildings and structures (separate from individual journeyman certifications) |
| Plumbing Contractor License | PC | Plumbing installations, repairs, and maintenance |
| Elevator Contractor License | LC | Installation, maintenance, and repair of elevators and conveyances |
Note: TrackMyVendor tracks company-level registrations and licenses only, not individual journeyman or apprentice certifications.
Washington registration number format
Washington contractor registration numbers use a unique format: last name + first initial + asterisk + suffix (e.g. JONESJ*123BC). Lookups fail when the asterisk is omitted — make sure to include it exactly as shown on your sub's paperwork.
What Washington L&I status codes mean
When you look up a sub's L&I registration or license, you'll see one of five status codes. Here is what each means and what action it should trigger before that sub sets foot on your job site.
The registration or license is current and in good standing.
The contractor has met all renewal requirements, maintained their surety bond, and kept workers' compensation coverage current. This is the only status that authorizes work. Note the expiration date — Active today does not mean Active in 60 days.
The registration exists but the holder is not authorized to perform work.
An Inactive registration may result from a voluntary election by the contractor or from an administrative lapse. Either way, an Inactive registration does not authorize a contractor to perform work requiring registration in Washington. Do not let an Inactive sub pull permits or perform construction work on your sites.
The registration or license period has lapsed without renewal.
L&I contractor registrations renew annually. Once expired, the contractor may not legally perform work requiring registration until renewal is complete. Work performed under an expired registration exposes you as the GC to stop-work orders and liability. Stop work for that trade and require a current Active registration before they return to site.
L&I has automatically suspended the registration.
Washington is unusual: L&I suspends registrations automatically — overnight, without notice — when a contractor's surety bond lapses or their workers' compensation coverage lapses. A sub whose registration was Active yesterday can be Suspended this morning because their bond renewed late. This is not a minor paperwork issue; it is a hard stop. Do not allow work to continue, and do not accept a sub's assurance that it is "being resolved."
L&I has permanently cancelled the registration or license.
Revocation is the most severe L&I enforcement outcome. A revoked contractor cannot legally work under that registration in Washington. Revocation typically results from serious violations, consumer harm, or failure to comply with prior enforcement orders. Remove this contractor from your approved vendor list immediately.
GC liability note: Washington has a GC registration requirement, but that does not shift the risk from your plate. If a job inspector finds an unregistered or Suspended sub working under your contract, stop-work orders, fines, and civil liability can attach to you as the responsible party. Knowing a sub's status at onboarding is necessary but not sufficient: L&I can suspend a registration mid-project with no advance warning.
Washington trade credential requirements by trade
Washington's licensing structure is more layered than most states. Several trades require dual credentials — one at the company level and one for the qualifying individual on file. Use this breakdown to confirm exactly what to verify for each sub you hire.
Any contractor performing work over $500 in labor and materials must hold a Construction Contractor (CC) registration from L&I. The registration requires a surety bond and proof of workers' compensation coverage (or a sole-owner exemption). If either lapses, L&I auto-suspends the registration.
L&I code: CC
Electrical contractors need two separate credentials: a company-level Electrical Contractor (EC) license and a current individual Electrical Administrator (EL) license held by the qualifying supervisor on file with L&I. A company EC license alone is not enough — if the qualifying individual leaves or lets their EL license lapse, the company loses authorization to contract for electrical work. Always verify both.
L&I codes: EC (company) and EL (qualifying individual)
Plumbing companies must hold a Plumbing Contractor (PC) license from L&I and maintain a named journey-level plumber as the qualifying supervisor on file. If the qualifying plumber leaves or their individual license lapses, the company's authority to contract for plumbing work is compromised even if the PC license itself is still current. Verify both credentials for every plumbing sub.
The dual-credential requirement for electrical and plumbing contractors in Washington is one of the most common compliance gaps GCs miss. A sub can hand you a valid company license number while their qualifying individual's credentials have quietly lapsed.
L&I code: PC
Companies performing elevator installation, maintenance, and repair must hold an Elevator Contractor (LC) license from L&I. Individual elevator mechanics also require separate L&I mechanic certifications. This is the most specialized credential on the L&I system and is typically relevant only for larger commercial projects.
L&I code: LC
Track Washington Electrical, Plumbing, and General Contractor Registrations Automatically
TrackMyVendor monitors specific L&I registration and license types — including the individual qualifiers that GCs most commonly miss. A bond lapse can suspend a registration overnight with zero notice to you.
Monitors Construction Contractor registrations daily. Washington auto-suspends registrations when a surety bond or workers' comp lapses — catch it the same day it happens, not at the next inspection.
Alerts at 90 / 60 / 30 / 7 days
Tracks both the company Electrical Contractor (EC) license and the qualifying Electrical Administrator (EL). If the EL leaves, the company's authorization to contract for electrical work is at risk — even if the EC still shows Active.
Alerts at 90 / 60 / 30 / 7 days
Monitors Plumbing Contractor (PC) licenses and their journey-level qualifier. One of the most common compliance gaps GCs miss — the company license can look fine while the qualifier's credentials have quietly lapsed.

Licenses verified through state data are clearly marked as Verified.
What Washington GCs actually track
License verification gets all the attention — but most GCs find their day-to-day compliance headaches come from the other two documents.
| Document | How often it expires | How most GCs track it |
|---|---|---|
| L&I Registration | Annually | Manually, or not at all |
| Certificate of Insurance (COI) | Annually or per project | By email, when they remember |
| W-9 | Per vendor | By request, often at year-end |
TrackMyVendor automates alerts for all three — most users set it up in under 10 minutes. Route them to Slack, Teams, Zapier, or Make →

What to do when a sub's Washington registration is expired or suspended
You ran an L&I lookup and found a problem. Here is the step-by-step response — and why most of these situations were preventable.
Stop that trade's work immediately
Do not let a sub with an Expired, Inactive, Suspended, or Revoked registration continue performing regulated work. Document the date and time you became aware of the status. If work has already been completed under a lapsed registration, note that in your records — it matters if a dispute arises later.
Confirm the status directly on the L&I contractor lookup
Run the lookup yourself on the Washington L&I public contractor search — do not rely on a screenshot or verbal assurance from the sub. L&I's lookup is the authoritative source. Save or print the results showing the date of your verification.
Contact the sub and give a clear deadline
For Expired registrations, the sub may be able to renew and restore Active status within a few days — give them a written deadline and require an L&I confirmation showing Active status before work resumes. For Suspended registrations, the most common cause is a lapsed surety bond or workers' comp lapse; the sub must cure the underlying issue before L&I will lift the suspension. For Revoked registrations, there is no deadline to give — the sub cannot legally work under that registration.
Find a backup sub if needed
If the sub cannot resolve the issue within your project timeline, you need a replacement who holds an Active L&I registration. Verify the replacement's status before they mobilize — not after. Use the registration number format (LASTNAMEI*SUFFIX) to confirm their lookup returns Active.
Review your other subs on active projects
One expired registration found on one project usually means it is time to check the rest of your roster. Washington's auto-suspension mechanism means multiple subs can lose Active status on the same day if their bond renewals cluster. Do this check now, not the next time a job inspector shows up.
Most of these situations are preventable
The common thread in suspended-registration incidents is the same: no one was watching between onboarding and the inspection. Washington's auto-suspension mechanism makes this especially dangerous — a sub's registration can go from Active to Suspended overnight with no notice to you. Manual spot-checks miss changes that happen between checks.
TrackMyVendor monitors every Washington sub's L&I registration status daily and alerts you the moment anything changes.
