OCR enforcement is adopted by cities of every size, from state capitals to mid-sized and small towns, whenever city hall decides to automate Zona Azul checks. There is no closed list: each municipality contracts the service on its own, so the map changes with every new tender. What can be stated as fact is the scale of the operation: Areatec maintains mobility solutions in more than 200 municipalities and runs the largest OCR fleet in the world. (Zona Azul is Brazil's paid rotational street parking.)
What OCR enforcement is
OCR stands for "Optical Character Recognition." Cameras read the license plate of the parked vehicle and the system verifies, in seconds, whether that car has active Zona Azul credit. At Areatec this work is done by the Olho Vivo car, which drives through the streets monitoring spot by spot without the agent having to get out to note plate by plate.
The reading runs on the Aretron platform, trained to identify plates in real street conditions: strong sun, rain, dirty or partially obstructed plates. The driver, in turn, activates the credit through the Digipare app, present in nearly 50 cities.
What kind of city adopts OCR
Instead of naming cities that change with every contract, it helps to understand the profile of municipality that tends to migrate to the technology. The examples below are illustrative, not an official list:
| Municipality profile | Why it adopts OCR |
|---|---|
| Capital or large city | High volume of spots and the need to cover large areas with few agents |
| Mid-sized commercial city | Ensures turnover of downtown spots, helping local commerce |
| Small or tourist town | Demand peaks on specific dates that on-foot enforcement cannot handle |
The common thread is city hall's decision to replace manual checking with automatic plate reading. Because it is a municipal choice, finding OCR does not depend on the city's size but on the local mobility policy.
What OCR changes in practice
- Uniform checking. The system reads every plate on the street with the same criteria, without depending on an agent's availability to pass each spot.
- More turnover. When enforcement is constant, drivers respect the spot's time limit, and the higher turnover benefits those who need to park near the shops.
- Wider coverage. A single Olho Vivo car covers in one loop what several on-foot agents would take hours to check.
How to know whether your city uses OCR
The direct way is to check the website of city hall or the municipal traffic authority and see which company operates rotational parking. Where the operation belongs to Areatec, activation is usually through the Digipare app, and enforcement drives around with the Olho Vivo car.
Watch the rule that applies across Brazil
Whether the city uses OCR or manual checking, parking in the rotational system without activating credit or beyond the allowed time falls under CTB Art. 181, XVII: a serious violation, a fine of R$ 195.23 and 5 license points, with removal of the vehicle as an administrative measure.
Some cities also adopt the TPU (post-use fee), an administrative charge that works as a second chance before the fine. The TPU is not a traffic fine, adds no license points, and its amount and deadline vary by municipality. Not every city has a TPU, so check your city's law.
