There is no single, stable public list of cities with an OCR car, because each municipality contracts its Zona Azul operation independently and the contracts change year to year. What can be stated with confidence is the overall picture: the technology is already present in hundreds of Brazilian cities, from capitals to interior towns, and Areatec runs the largest OCR fleet in the world, serving more than 200 municipalities. (Zona Azul is Brazil's paid rotational street parking.)
Why you can't pin down a closed list
Electronic enforcement of Zona Azul is each city hall's decision. One municipality may adopt the OCR car this year, another may switch operators next year, and a third may use the technology only in part of downtown. So any list that promises to name "all cities with OCR" ages within a few months and tends to mix in outdated data.
The correct way to know whether your city uses an OCR car is to check the official source: the website of city hall or the municipal traffic authority, and the official app for the local Zona Azul. That is where the operator, the type of enforcement and the current rules are listed.
What Areatec represents in this scenario
Areatec has operated in the sector since 1996 and develops automatic plate-reading technology for rotational parking. Today the company runs the largest OCR fleet in the world and is present in more than 200 municipalities. The Digipare management system is used by around 50 cities.
These numbers convey how widespread the technology is. Instead of trying to memorize a list of cities, drivers gain more by understanding that the OCR car is already a reality across much of the country and tends to expand.
How the OCR car works on the street
The vehicle equipped with reading cameras captures the plates of parked cars as it drives along streets with Zona Azul. Each plate is compared, in real time, with the database of paid activations:
- The car follows a programmed route through the regulated streets.
- The cameras record the plate, the time and the location.
- The system checks whether that vehicle has a valid activation.
- If the activation exists, nothing happens.
- If there is no activation or the time has expired, a record is generated with a photo, date, time and coordinates.
Areatec's embedded enforcement solution is Olho Vivo Patrol, which relies on the Aretron platform to process the readings. In operations that still combine a manual approach, the agent uses the digital booklet to record findings in the field.
What happens if you didn't pay
Once an irregularity is identified, the outcome depends on the municipality's rules:
- Cities with a TPU (post-use fee): the system generates an administrative fee to regularize the use of the spot. The TPU is not a traffic fine and adds no license points. The amount and the deadline vary by city, so check your city's law.
- If the TPU is not paid, or where it does not exist: the case may be ticketed as a traffic violation.
The fine for parking in disagreement with regulated parking is set out in Art. 181, item XVII of the Brazilian Traffic Code. It is a serious violation, with a fine of R$ 195.23 and 5 license points, plus the possibility of vehicle removal. This is the only fixed nationwide amount; everything that comes before it (TPU, deadlines) varies according to the local rule.
Practical summary
- There is no closed, up-to-date official list of cities with an OCR car.
- The technology is already in hundreds of municipalities, and Areatec runs the largest OCR fleet in the world, in 200+ cities.
- To find out about your city, check city hall or the official Zona Azul app.
- If you paid and respected the time: the OCR car does not affect you. If you didn't pay: there may be a TPU (varies by city) or the serious fine under Art. 181, XVII.
