Patents with letters Q, R, S, T, U, V, W, X are patented cars before 1995.
This system was created from 1958, when in Argentina it was created that National Registry of Property of the Automotive (RNPA), whose first objective was to unify, regulate and standardize the different identifications or cars patents.

Before 1995 the cars were evident with 6 numbers and a letter.
These patents, which lasted three decades, had a particularity: Each province was identified by a letter, followed by six numbers.
The background was black and the white letters. The former had a very fine white frame and characters, which made their readability difficult, so at the beginning of the seventies the edge was eliminated and the letters and numbers grew in size.
TO Each province (Together with the City of Buenos Aires, which for that time was not autonomous, and Tierra del Fuego, which was national territory) was assigned a letter. The I and O, due to their similarity with numbers 1 and 0, were discarded. Thus the letters were assigned:
- A was assigned to Salta
- B A BUENOS AIRES
- C to the Federal Capital
- D A SAN LUIS
- E to between rivers
- F to La Rioja
- G to Santiago
- H a Chaco
- J a San Juan
- K a Catamarca
- L to the pampa
- M a Mendoza
- N to missions
- P a formosa
- Q a Neuquén
- R to Río Negro
- S a Santa Fe
- T a Tucumán
- U a Chubut
- V to Tierra del Fuego
- W to Corrientes
- X to Córdoba
- And Jujuy
- Z to Santa Cruz
A problem appeared in 1973 when the Province of Buenos Aires exceeded one million patentswhich forced to add a number, which was below the letter. In 1980 the Federal Capital reached one million and the province reached two million in 1984. They were the only two jurisdictions that needed the seventh digit.
