To register your Charger, just select the “To Register” menu, fill in the blanks and hit send. At the very least, the VIN is required. Ideally if it is possible to supply the codes from the fender tag, submitting those as well is where we gain the greatest insight into the way these incredible vehicles were assembled. Your name and location are also very helpful.
Your name, address and the specific information (serial number) about your Charger are never made public. Similarly there is no use in requesting this information about Chargers belonging to anybody else. Legitimate requests to contact someone can be passed along, however, should the other party not wish to grant your request then the issue dies there. Owner privacy is extremely important in this endeavour.
