Welcome to the Ford Mustang S-Code Registry. The purpose of the S-Code Registry is to collect and document data of existing S-Code Ford Mustangs. If you are a current S-Code owner and would like to add your vehicle to the registry, a simple and intuitive submission form has been developed. While we encourage to add as much data as possible, only the VIN is required to submit the form. Once a vehicle is added to the registry, it instantly gains it's own profile which can be viewed and searched.
