Vehicle Registration Plates of Spain (Paperback)

High Quality Content by WIKIPEDIA articles! There have been three main forms of Spanish vehicle registration plates, with the system being changed recently again. Until the early 1970s, the plates just included the province code and a sequential number. Older vehicles with five or six digits and a province code can still be seen on the roads. This system was discarded on October 1971 when Madrid and Barcelona both nearly reached the number 999999. The next system in place was of the form XX-NNNN-YY (black digits on white plate), where XX is a one- or two-letter code denoting the province the car was registered in (complete list), NNNN is a four digit number to make the plate unique (zeros on the left are shown), and YY is a one- or two-letter code which is incremented by one place after the four digit number reaches 9999 - for example A-9999-Z is followed by A-0000-AB (should be AA, but some letter combinations were not in use).
