Verifying the Vehicle Identification Number (VIN) and its validity is essential when examining a vehicle's registration because the VIN is a unique code used to identify individual motor vehicles. It provides critical information about the vehicle's make, model, year, and country of manufacture, ensuring that the vehicle being inspected matches its registration details. Validity extends to checking that the VIN is not associated with a stolen vehicle or flagged for any legal issues, which is crucial for ensuring compliance with state regulations and enhancing road safety.

While vehicle color and license plate number can be relevant for identification, they are not as definitive as the VIN in establishing the vehicle's identity. Previous owner details and service history may provide useful information but do not impact the immediate verification of the vehicle’s registration status. Insurance coverage and mileage are also important but serve different purposes in vehicle evaluation and are not fundamental to the registration verification process.
