NVIP, the National Vehicle Identification Program, maintains a database of registered vehicles that have been equipped with after-market products that reinforce the vehicle's valid identity. Companies participating in NVIP include a form with their products that allow customers to register a vehicle with NVIP for free.

In the event that an NVIP-registered vehicle is stolen, NVIP is available to help police uncover identity-disguising alterations made by thieves in order to determine the true identity of the vehicle.

NVIP offers rewards of up to $1000.00 for information that leads to the recovery of an NVIP-registered stolen vehicle and the apprehension and conviction of the thief.

As an additional benefit, any NVIP-registered vehicle will automatically be registered with StolenCarReports - 'The Nation's Neighborhood Watch for Stolen Vehicles' upon notification of the theft.

Products that offer free registration in NVIP include VINetcher's, do-it-yourself VIN etching system, Plate Lockers's license plate security kits, and others.
