Since September 2000, Spanish registrations have followed a nationwide sequence of four numbers and three letters, replacing the former province-based system. The ordinary registration number identifies a vehicle across Spain rather than indicating where it was registered; the DGT has likened it to a vehicle’s identity document. The format is used by most of the country’s vehicle fleet, which a DGT explanatory article put at around 34.8 million vehicles.
Published estimates put the change in 2027. The timing depends on how quickly the remaining N combinations are used, and the Dirección General de Tráfico (DGT) has not announced an official date. Its "Última matrícula" tracker displayed NTY on 10 November 2026, still within the N series.
The final planned N combination is NZZ; the next will be PBB. The transition concerns the ordinary white registration series, not every type of Spanish vehicle plate. Spain also uses other plate categories, including yellow plates with black characters for light vehicles and mopeds.
O is excluded under rules that have applied since the current system began. The five vowels are omitted to avoid unsuitable combinations, including examples such as ANO and PIS. Ñ can be mistaken for N, while Q can resemble zero. CH and LL are excluded as well.
The switch applies only to vehicles registered for the first time after the N series runs out. Existing owners will not have to replace their plates, pay a fee or complete additional paperwork.
