Format, years and the law

Format
LL-999999, for example PL-539448 (L is any letter, 9 any digit)

The letters name the issuing province (M for Madrid, B for Barcelona); the digits simply count registrations in that province, from 1 upwards.

The format above is broad: a registration that fits it has the right shape, which does not show that this series issued it.

Years issued
1900 to 1971. No longer issued.
Vehicle class
Standard: the default series issued to private road vehicles. Issued for car, van, truck, bus, and motorcycle.
Colours
Characters #000000 Background #FFFFFF
About this plate
PERIOD HONESTY, stated at point of use: 1900 dates the REGISTRATION regime (RD 17-09-1900); the earliest plates displayed province + number NON-UNIFORMLY, as the 1907 preamble itself testifies; the prescribed FORMAT begins with RO 24-05-1907. The era closes on 07-10-1971 (Decreto 2046/1971 in force), with old plates valid indefinitely (DT 1.ª), so numeric plates remained ON THE ROAD for decades past 1971, exactly as provincial suffix plates remain today. The 1900 start also honours the lint's period rail (first national plates 1893; Spain 1900).
Region code notes
This era's lists differ per instrument (1907, 1918, 1926, 1934 art. 232, 1971 art. 233): three-letter codes until at latest 1926, no Gran Canaria/Tenerife split in 1907, Sahara SH in the 1971 list.
How numbers are issued
Strictly sequential per province: the number is "el número de orden del permiso de circulación" (1918 art. 13.d, 1926 art. 15.d, 1934 art. 232, the 1907 text says "de la licencia").
About the format
The contraseña ran ONE TO THREE letters: the 1907 list includes three-letter codes (Albacete ALB, Cáceres CAC, Castellón CAS, Segovia SEG, Teruel TER), trimmed in later lists. The number is the province's permit order number with NO fixed width, it grew with the province's registrations, from 1 digit to 6 (art. 233 of the 1934 Código contemplates "cinco o más cifras" and Madrid exceeded 600000 before 1971).
Separators
The guión is statutory throughout: 1907 concl. 3.ª "separado por un guión", and every subsequent dimensions table (1918, 1926, 1934) carries a "Longitud del guión" row.
