Conn. Gen. Stat. § 14-12r: Inspection of vehicle identification number.

Before issuing registration for any motor vehicle that has not been previously registered in this state, except a new motor vehicle, the Commissioner of Motor Vehicles may require an inspection of the manufacturer's vehicle identification number. Such an inspection may be performed at any designated official emissions inspection station or by any other business or firm authorized by the commissioner to perform safety inspections in accordance with sections 14-12 and 14-16a or by any motor vehicle dealer or repairer, licensed in accordance with section 14-52 and meeting qualifications established by the commissioner. If the inspection is performed by a licensed dealer or repairer, and is not performed in connection with an official emissions inspection, such dealer or repairer may charge a fee to the owner in an amount not to exceed twenty dollars, provided an affidavit relating to such inspection is furnished to the commissioner in accordance with the provisions of subsection (d) of section 14-99h.
