Drivers are being urged to check their licence plates before new rules come into place.
In England, Scotland, and Wales, a brand new "23" age identifier will be introduced next month. It's the latest issue following the "72" number which was introduced last September while "22" was rolled out last March. Since 2022, the DVLA has issued two new age identifiers with old-style prefix letters being released every year.
Motorists can find these identifiers in the third and fourth numbers visible on any licence plate. The first two letters of a number plate show where a vehicle is registered according to its region and local DVLA office, while final three letters on a number plate are issued at random, the Mirror reports.
