A current Gibraltar rear number plate, featuring the GBZ country identifier under the European flag.
From 1912 to 2001 Gibraltar number plates consisted of the letter "G" (for Gibraltar) followed by a series of digits issued in numerical order. The maximum number of digits was five, so the first registration plate should have been "G 1" - in fact the first plate was "GBZ 1" - and the last was "G 99999". A new system was introduced in October 2001, in anticipation of running out of registration numbers once reaching "G 99999". The new system consists of the letter "G" followed by four digits (1000-9999) and another letter. The last letter represents the series. For example, series A consists of all registration plates from "G 1000 A" to "G 9999 A". The next series is B, and so on. Currently (October 2012), registration plates in Gibraltar are in series D. The European flag is also now featured, along with Gibraltar's international vehicle registration GBZ.
Military vehicles in Gibraltar display regular UK military plates in the format nnLLnn. Most military vehicles in Gibraltar use the letters "RN" (reserved for Royal Navy vehicles), although some use other letters indicating that they are from Army or RAF. UK military vehicles do not carry national identity ovals, but sometimes display a small Union Flag.
The Governor's official car, following tradition, displays a Crown, in place of a registration plate with a number.
Some motorcycles display their taxation disc attached to the licence plate.
Temporary/export plates are similar to, and in the same series as, the regular issues. However at the right hand side of the plate is a green band, showing month and year of expiry. Until 2001 temporary tourist (duty free) plates had registrations from the normal series except that the prefix used was GG. This series reached past GG90000, and was probably superseded by the dated green band style when the suffix letter was introduced.
Dealers' plates are light blue with the letters DLR and a serial number in white. These are usually magnetic plates, but also can be simply written on paper or cardboard etc.
