You need to know the size of the number plates that are allowed to be used for personal or official cars in your country. We do not suggest you guys not follow the rules that must be abided by the people at all times. You might also need to know if the traffic authorities allow stamped or embossed car name plates so that you have everything in mind before you start working on your designs. It is not only important for the stage when you will have the car name plates manufactured but this information will also help you think of the relevant designs which will complement the finishing of the plates later on.
