How To Find Your Serial Number
Each trailer Ifor Williams manufactures is fitted with a type plate, this has a unique serial number printed on it by multi-dot punching. An example of a standard type plate is shown below. This example is printed with the full 17 digit VIN (Vehicle identification number). The last 6 or 7 digits represent the serial number depending on the age and model of your trailer (in this example 374538). Some models may be fitted with a slightly smaller plate, however the serial number will still be present and easily recognisable.
For trailers with “A Frame” drawbars the plate is located on the outside of the left hand drawbar member (looking at the trailer from the front). On trailers with adjustable height couplings the plate is located on the left hand section of the supporting structure that the drawbar / coupling unit is clamped to (looking at the trailer from the front).
On P5/6/7e (unbraked) models the plate is fitted to the front panel of the trailer, or is sometimes attached to the drawbar mounting bracket. On BV64e boxvan models the plate is fitted to the left hand side of the rear cross member (looking at the trailer from the front).
