Did you know, there’s no difference between a trailer number plate and a standard rear car number plate? It's the same for caravans: they’re exactly the same thing, and you can buy precisely what you need here at Replacement Number Plates.
If you tow a trailer or caravan in the UK, it must display the same number plate registration as the vehicle you are towing it with.
For trailers and caravans, we recommend purchasing either a standard rear oblong plate or a standard rear 4×4 plate. Both retail at only £9.99. For the avoidance of doubt; rear number plates (trailer number plates) are yellow.
