Plate Details

C21 KEY is a prefix-style registration, identified by the letter C at the start of the plate. The prefix letter C corresponds to the 1985 registration period. Under DVLA rules, this plate can be assigned to any vehicle first registered in 1985 or earlier. Prefix plates were issued between 1983 and 2001 and remain popular for their clean, readable format.

Registration History

C21 KEY was first made available in January 2023. The original issuing office for this combination is Anglesey C.C.. Local council and county borough offices issued plates within their geographic area — the issuing office identifies the regional origin of the registration. C21 KEY has DVLA auction history, having been offered at a DVLA auction in January 2023. The DVLA cherished transfer programme was launched in 1989, opening previously reserved registrations to the public for the first time. Plates are selected for DVLA auctions based on their perceived collectability and desirability — an auction appearance is a recognised indicator of a registration's historical market standing and collector appeal.
