1 XKB private number plate

1 XKB is a dateless UK private number plate with a straightforward one number followed by three letters format, offering a concise four-character registration. As a number 1 plate, it represents the pinnacle for any initials combination, being significantly more sought after than plates with higher numbers. This format is characteristic of dateless registrations, which do not show a year identifier and are often favoured for their clean, timeless look. The '1' holds particular significance, with research indicating that registrations beginning with this number have a distinct positive effect on collector appeal.

The XKB initials are considered niche with lower demand, offering a degree of rarity. Despite this, the plate's primary appeal lies in its prominent '1' and its short, desirable format. Dateless registrations from the earlier eras of UK vehicle registration are generally the most sought after, and shorter plates typically hold stronger appeal, making 1 XKB an attractive proposition for collectors and individuals seeking distinct personal registrations.

This registration first entered circulation through a DVLA auction in 2025. It sold for £10,388 (hammer price).
