21 CJ private number plate

21 CJ is a four-character dateless registration with a numbers-first, two-by-two format. Its brevity and clean dateless appearance contribute to its appeal, and the 21 paired with the initials CJ offers a concise and memorable combination for those seeking personalised registration plates. The number 21, occupying the single-digit band for numbers-first registrations, generally carries stronger appeal than higher numbers within the comparable number bands, and fewer digits typically result in a shorter, more streamlined registration. The initials CJ are estimated to have very strong popularity, indicating a broad potential audience of buyers.

The registration 21 CJ is notable for its potential connection to the boutique hypercar marque Czinger and their model, the 21C. This direct mirroring of the registration to a distinctive vehicle designation may be of particular interest to enthusiasts and owners of such high-performance vehicles, providing a strong motoring or aspirational angle.

As a dateless registration, 21 CJ does not carry a year identifier, offering the clean look associated with registrations from earlier eras. Dateless registrations of this format are highly sought after, with the earliest, very short registrations pairing one or two letters with a single number described as the most desirable historic formats.

This specific registration was released to the open market via DVLA auction in 1992. It sold for £3,361 (hammer price).
