A trailer serial number acts as a form of identification for your property. Many trailers are similar in appearance therefore it is vital you supply us with the unique serial number to distinguish and identify your trailer. This is normally found on the chassis/frame of the trailer and sometimes on paperwork that accompanies the trailer during purchase. It can often be a mixture of letters and/or numerals. If you cannot find this, or if your trailer does not have one, it is often difficult to provide insurance for.
