The British Standard sets out the physical characteristics on the number plate. This includes:

• Visibility
• Strength
• Reflectivity

The British Standard also requires that a number plate must be marked with the following information: -

• The British Standard Number (currently BS AU 145d)
• The name, trade mark, or other means of identification of the manufacturer or component supplier. (The company who actually make the number plate.)
• The name and postcode of the supplying outlet. (The 'supplying outlet' is taken to mean a company whose business consists wholly or partly of selling number plates.)
• A non-reflective border and the Euro-symbol with the national identification letters are optional additions.
• There shall be no other markings or material contained on the number plate.
