South Carolina Altering Vehicle Identification Numbers (SPAVIN) is a program that allows vehicle owners to have their vehicle identification numbers (VIN's) altered. This is done for security purposes and to prevent theft. The process involves changing the VIN to a new, unique number that is specific to the vehicle. There are two types of SPAVIN: standard and enhanced. With the standard option, the owner can change the existing VIN to a new one. With the enhanced option, the owner can have the entire VIN changed, including the characters. Both options require the vehicle to be inspected and the new VIN registered with the South Carolina Department of Motor Vehicles.
