Vehicle registration plates of Brazil

Brazilian vehicle registration plates are issued by the states. Each state has a "Departamento de Trânsito" (DETRAN) that is in charge of vehicle registration and car tax collection, but plates are standardized across the country and form a national vehicle registration database.
Description.
The current system, being phased out in favor of Mercosul standard plates, was created in 1990 and was named "Registro Nacional de Veículos Automotores" (RENAVAM). It uses the form "LLL·NNNN", where LLL is a three-letter combination followed by a four-digit number with a dot between the letters and numbers. A combination given to one vehicle stays with it "for life" - it cannot be changed or transferred to another vehicle. Vanity plates are allowed as long as they abide to the same standard as non-vanity plates.
Above the combination is a metallic band with the State abbreviation (SP = São Paulo, RJ = Rio de Janeiro, PR = Paraná, AM = Amazonas etc.) and the name of the municipality in which the vehicle is currently registered. This band has to be changed when a vehicle needs to be registered in a different municipality. 
Rear number plates are bound to the vehicle by a plastic seal. Broken seals invalidate the number plate, which has to be re-sealed by the authorities. Seals need to be broken in order to change State/Municipality tags.
The size of the Brazilian license plates has been standardized to 400 x 130 mm (15" x 5" approx.) in 2008. That standardization also requires a unique typeface known as "Mandatory", which is similar to the typeface used on British plates introduced there in 2001. Plates in North American standard or European standard size can no longer be used as of January 1, 2008.
Letters.
The letters on the license plate can describe the state where a vehicle was originally registered. Vehicles relocated from one state to another will show the new state/municipality on the replaceable tag, but it is always possible to determine the place of original registration for a used vehicle by observing the license plate range for each Brazilian State: 
2018 Mercosur standard.
In October 2014 the design of the new license plate to be used by all Mercosur countries was officially presented. This consists of a plate of , with a white background, the characters and frame in black and a blue band at the top that shows the name of the country, its flag and the Mercosur logo. The typeface used is FE-Schrift.
In September, 2018, Mercosur standard license plates started to be adopted in Rio de Janeiro. As of January 2020, all states have started issuing the new plates. By the end of 2023, all vehicles are expected to be carrying these new plates.
