Vehicle registration plates of Spain

Vehicle registration plates are the mandatory number plates used to display the registration mark of a vehicle, and have existed in Spain since 1900. Most motor vehicles which are used on public roads are required by law to display them. The government agency responsible for the registration and numbering of vehicles is the Directorate General of Traffic.

They currently use the format L nnnn LLL where:

This format, introduced on 18 September 2000, is used nationwide, so there is no way of knowing where the vehicle was registered. The "counter" gives a rough idea of when the vehicle was registered, but is less reliable for determining its age, as imported second-hand vehicles are registered in the same way as new models.

As of August 2015 the "counter" combinations are at the J series, which began in late 2014 with JBB. At the current rate of approximately five series per decade, the system will be exhausted around 2040.

The plates themselves are white with black characters, front and back, with a blue strip on the left containing the 12 stars of the flag of Europe and the country identifier E (for España). This strip is compulsory. The plates are usually rectangular and wide in shape, but there are also square-like plates for motorcycles, while some cars have a narrow plate inset (such as at the back of the SEAT 600).

Two previous systems have been used, both of which were province-based.

The first system, introduced in 1900, consisted of a letter code denoting the province the vehicle was registered in (the full list of codes appears below), followed by a sequence number of up to six digits (XXX-NNNNNN). The codes were normally made up of the first one or two letters of the province name or the name of the provincial capital (many provinces are named after their capitals), under the provisions of a 1926 regulation. In the earliest days, some provinces used three-letter codes, but these were abolished after 1926.

This system came to an end in October 1971, by which time both Madrid and Barcelona were approaching the number 999999. Older vehicles with such registrations, usually with five- or six-digit numbers, can still be seen on Spanish roads.

In the later years of this system, many plates were white with black characters. Today, there are a few rare cases where the blue EU country identifier strip is also carried.
