Statewide marketing platform: free VIN lookup, find a mobile tester by city/ZIP, and official CARB links. Testing network includes NorCal CARB Mobile and CA partners. Not affiliated with CARB.
Book / testing desk: testing@carb-clean-truck-check.com · book@ · info@
We never invent compliance status. Decode with the federal VIN database, then use official CARB Clean Truck Check portal for the state’s record. If you’re due or blocked — solutions below (mobile test, book, city pages).
cleantruckcheckvin.app — VIN lookup only (separate product). NHTSA decode + official CARB portal. Does not invent compliance.
Federal VPIC decoder (source of truth for make/model/engine). Same data our free app uses.
State portal for fees, vehicles, compliance. Always verify the legal answer here — we don’t invent it.
Compliance bulk + photo OCR for Bryan/agents. Separate from this public homepage.
Status comes from CARB / NHTSA — never invented here. Need a mobile tester? Pick a town page or ZIP router — phones still ring 916-890-4427.
Shows county for any ZIP (even 90210) and our number until local partners are live.
mobileovitest.com — vague hub for the Bakersfield to LA corridor. Specializes in OVI smoke for 2012 & older engines + fleet mobile. Not a NorCal city brand. Phone is ours.
mobilecarbtest.com — vague hub for LA through Orange County to Carlsbad. Cities live on the page; domain stays generic. Phone is ours. Does not replace NorCal.
mobilecarbsmoketest.com — San Diego end of the chain (SD County cities on that site). Calls still ring our line.
Call/text 916-890-4427 · say city + # trucks. We match the hub or satellite.
CARB’s for-hire credentialed testers if you need someone else near you.
NorCal stays NorCal (named domains + norcalcarbmobile.com). SoCal uses three vague hubs only: Bakersfield → LA (mobileovitest.com) · LA → Carlsbad (mobilecarbtest.com) · San Diego (mobilecarbsmoketest.com). Town tiles below open the right hub. Every door rings 916-890-4427.
Testers and shops in markets we don’t day-cover (Redding, far-north, overflow counties) can sign up here. You show on the “Others” list. When we dial partners: monthly lead seats. On signup we send a free city-page kit (copy-paste HTML — also open /free-city-kit).
Names of towns only — no private phone numbers shown on the homepage.
Partner / other signup
Or call/text 916-890-4427 and say “partner signup + town”.
Live sites below are NorCal CARB Mobile network (IF530523) unless marked partner later. Homepage city tiles + this list help Google and humans see the whole map. Default book line: 916-890-4427.
Short, extractable URLs. Every page leads to 916-890-4427.
Prefer text? Message the AI book line (Hermes + Twilio).

A human still confirms the slot — Bryan does the test. Brand call line stays 916-890-4427.
