Trace a Registration Mark

This page will take you through to details of the authority which originally issued the registration mark and give details of whether they survive.

If you already know the authority, simply type the name in the Search box and click on the result. If you don’t know the authority, click on the Mark box and type the last two letters of the registration. This will bring up the name of the issuing authority – click on that name for full details.

Note that with three-letter marks, it is the last two which are the significant ones so that, for example, Hampshire has BAA, CAA, DAA and so on.

Number plates

If you have already searched for a mark click on it below the Mark box to return to the full search. Similarly delete a location search before looking for a mark.

Because the location list is divided into three sections and also because many of the local authorities no longer exist under the same names, a code is given after the registration mark to show in which list a particular authority will be found. The codes are E (England and Wales), S (Scotland) and I (Ireland).
