What a VECI label actually is
A VECI label is the factory Vehicle Emission Control Information sticker under the hood. It is not the Monroney. It is not a smog certificate, and it is not the VIN plate alone.
Is the underhood emissions sticker the Monroney? No. People also treat it like a smog certificate, or like the metal VIN plate by itself. Those are different papers.
A VECI label is the factory Vehicle Emission Control Information sticker. It sits in the engine bay — hood underside, radiator support, strut tower, or firewall. It names the manufacturer, the test group or engine family, the equipment list or vacuum diagram, and the standards that build was certified to. It is not the Monroney in the glass. That sheet is price and the EPA mpg block. It is not a smog certificate. It is not the VIN plate alone.
Older labels printed the vacuum diagram and the parts list on the same face. Newer ones keep the heading and the compliance line, then point at a test group. Same job: say what this VIN was certified as.
Why it matters: a California vehicle verifier filling REG 31 has to look at the emission label. Section 9 asks what that sticker indicates — US EPA only, California only, both, exempt, or none — and the test group if it is there. That is a look at this factory sheet, not legal advice.
Texas does not run a REG 31 twin. Inspections there are recorded electronically. The factory VECI is still the underhood tell.
