In 2025, the Mercosur Standard License Plate Remains the Official Model in Brazil, but Without Immediate Obligation. Drivers Only Need to Change in Cases of Transfer, Change of City, or Damage to the Old Plate
The vehicle identification plate in the Mercosur standard has been part of Brazilian reality for over five years, but even in 2025, it still raises doubts and speculation among drivers.
After all, is there any concrete change this year? Will it be mandatory for all vehicles still using the old gray model?
The answer is simple: the Mercosur plate remains the official standard, but the replacement is not automatic or immediate. What exists, in practice, are specific situations that require replacement and specific adjustments determined by the National Traffic Council (Contran).
What Remains Valid and When Replacement Is Required
According to Contran, the basis of the vehicle identification system (PIV) remains the same. This means that the old gray plates remain valid and the driver does not need to change them if there is no legal reason.

Any Brazilian over 18 years old can now choose at a notary who will take care of their assets and decisions in case they lose capacity in the future, thanks to self-curatorship, an instrument that gained national strength with a CNJ regulation from October 2025 and changed estate planning in the country.

Brazilian justice orders the Union, Iphan, Pará, and the City Hall to “save” the ghost town of Fordlândia from ruins, with a diagnosis in 90 days, land regularization, and fines for the abandonment of historical heritage.

Braking only in front of the radar and accelerating right after may no longer be an option for drivers, because BR-101 in Espírito Santo tested a system that measures the average speed over an entire stretch and caught a car at 124 km/h on a 60 km/h road.

The STJ decides that a woman who left her career for more than 30 years to take care of the house, children, and family is entitled to lifetime alimony after divorce; the decision by the 3rd Panel recognizes extreme financial vulnerability and values invisible work in marriage.
Replacement becomes mandatory only in three cases:
- When there is a transfer of ownership of the vehicle;
- If the owner changes municipality;
- Or if the old plate is damaged, stolen, or lost.
In any other scenario, the vehicle can continue to operate with the gray plate without risk of being fined.
The important thing is to keep the licensing and registration updated, adhering to the rules of the local Detran.

Prices Vary According to the State
Another point that creates confusion among drivers is the cost of the new Mercosur plate, which varies according to the region and type of vehicle.
Data collected in the first quarter of 2025 indicates that the cost can range from R$ 138.24 to over R$ 225.25, depending on the state.
The price includes printing and installation performed by companies accredited by the state Detrans. In some municipalities, additional service fees may also be charged, raising the final amount.
Are There Changes in 2025?
Despite rumors on social media, there is no national determination mandating the immediate replacement of all plates.
What is happening is a gradual expansion of the Mercosur system, which is already required for new vehicles and in all cases of re-registration.
In other words: those who buy a brand-new car in 2025 will leave the dealership with the new plate, while those who have a vehicle with a gray plate can continue using it until one of the stipulated replacement situations occurs.
In summary, 2025 does not bring a “general replacement” for the Mercosur standard, but reinforces the definitive transition to the system, consolidating the model that visually unifies vehicle identifications among the countries in the bloc.
The Importance of Following State Regulations
Each Brazilian state may adopt complementary regulations regarding the issuance and deadlines for replacement. Therefore, drivers should pay attention to announcements from their local Detran.
Ignoring these rules can lead to issues during inspections, licensing impediments, or even fines.
The Mercosur standard was created to standardize the registration system among Brazil, Argentina, Uruguay, and Paraguay, facilitating identification and reducing fraud.
Even without drastic changes this year, the trend is for the model to become universal for all Brazilian vehicles over the coming years.
