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.
The current system, being phased out in favor of Mercosul standard plates, was created in 1990 and was named Registro Nacional de VeÃÂculos 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 by the same standard as non-vanity plates.
Above the combination is a metallic band with the standardized state abbreviation 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 ÃÂ 130 mm (15" ÃÂ 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 1 January 2008.
The letters on the license plate can describe the state where a vehicle was originally registered. Vehicles transferred from one state to another will display the new state/municipality on the temporary plate, but it is always possible to determine the original registration location of a used vehicle by observing the letter sequence on the plate for each Brazilian state.:
Below is an alphabetically organized list of Letter Sequences and corresponding States. This list is up to date as of January 2026.
Note: The SAV sequence was first used by São Paulo in September 2009, but was discontinued using only SAV 0A01 to 1A00, later the remainder of the sequence was assigned to Ceará in December 2021, being SAV 1A01 to 9J99.
Available combinations for State (up to january, 2026):
In October 2014 the design of the new license plate to be used by all Mercosul 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 Mercosul logo. The typeface used is FE-Schrift.
In September, 2018, Mercosul 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.
The Mercosul license plates have a new alphanumeric format that will allow for more available combinations. While the previous system used a LLL-#### format, the new format is LLL#L##. Vehicles who are to switch their old license plates for the new one will retain their previous license plate number, with the exception of the 2nd digit (5th character). The number in that position of the alphanumberic format is being replaced by a letter, in accordance with the below table.
