MW Registration Code History

MW series of older UK registration numbers

The MW registration code forms part of the historic UK vehicle registration system used before the introduction of modern number plates. This code was originally associated with Wiltshire.

The information on this page records known registration series connected with the MW area code, together with their approximate issue dates where these are known. Most of the information relates to registrations issued between 1900 and 1972, meaning vehicles registered later may not necessarily appear in these records.

Historic registration codes are particularly useful when researching classic cars, motorcycles, commercial vehicles and other vintage vehicles. They can also help date old photographs, films and log books, or assist owners looking for a suitable age-related replacement registration.

MW registrations from Wiltshire

The MW code was allocated to the Wiltshire area. Before computerised registration systems, these letter combinations identified the local licensing authority responsible for issuing the number.

Many post-war registrations used three-letter combinations. In these cases, the second and third letters frequently represented the local area code. Vehicles carrying registrations containing MW therefore have a historic connection with Wiltshire.

Earlier vehicles carrying two-letter registrations using MW would also have been issued within this area.

Some codes were reused during different periods of the twentieth century, making the dates an important part of identifying a vehicle's age.
