2 Digit Number Plates — Ultra Rare Single Letter Registrations

2 digit number plates are among the rarest and most prestigious registrations in the UK. These plates contain just one letter and one number, making them the shortest and most exclusive private registrations ever issued. Because of their extreme rarity, they are widely recognised as premium number plates and are often considered investment number plates. Some of the most expensive number plates ever sold — including famous registrations like A1 and F1 — fall into this elite category.

What Are 2 Digit Number Plates?

In the UK private registration market, true 2 digit plates contain

One letter + one number only

There are no additional characters — just a single letter and a single number. These registrations belong to the dateless number plate system, meaning they carry no age identifier and can be assigned to vehicles of any age.
