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.
Scan VIN labels in the field + tips. Companion to the free VIN app.
Status comes from CARB / NHTSA — never invented here. Need a mobile tester? We route by geography. San Diego County → San Diego site only, not the NorCal homepage.
Opens the right satellite site (Hayward, Stockton, SD, Sac…). Replaces old “everything → NorCal” backend links.
mobilecarbsmoketest.com — SD NAP & pricing only. Unknown city stays on NorCal / this hub router.
Call/text 916-890-4427 · say city + # trucks. We match the satellite.
CARB’s for-hire credentialed testers if you need someone else near you.
Every site below is the same licensed tester (NorCal CARB Mobile · IF530523). This hub / field app passes link equity to city & service pages so Google treats them as one network.
Text or call with: city · # trucks · OBD or smoke · preferred day. We confirm fast.
