Posadas is the capital of Misiones and a border city: the waterfront on the Paraná, Uruguay, Quaranta and Mitre avenues and National Route 12 concentrate a traffic of motorcycles, Paraguayan cars crossing the San Roque González bridge and trucks of yerba mate, timber and tea heading south. Municipal fines are issued by the city; route fines are issued by the province and coexist on the same plates.

Context and authority

Like every municipality in Misiones, it applies the National Traffic Law 24.449 through the provincial adhesion: fixed-unit amounts, a two-year limitation for minor offences and five for serious ones, and a defence before the court that issued the fine. Provincial fines are covered in the Misiones article.

The municipal misdemeanour court rules on fines issued within the city: helmets, seat belts and documents at municipal checks, speeding and red lights on the camera avenues, and parking downtown and on the waterfront. A defence is filed with the court within the period set by the notice; fines on Route 12 and at the bridge approach are not municipal.

What the API returns for this jurisdiction

A plate lookup in Posadas walks the Posadas municipal misdemeanour court together with the integrated provincial sources of Misiones, and returns each fine with the authority that issued it:

  • Authority and fine number exactly as each court publishes them.
  • Date, location when reported and description of the infraction.
  • Amount, status and payment conditions published by that court.
  • Downloadable payment slip when one exists.
  • Coverage per source and partial-result flag.

How to check a plate in Posadas

To check a plate by hand there are three places: the Posadas municipal portal for municipal fines, the provincial circuit described in the Misiones article and the ANSV national lookup for fines loaded into the national system. With ten vehicles that is enough; with a hundred, the API walks every integrated source by plate and returns the result split by authority.

What to watch if you run a fleet in Posadas

A yerba mate or timber truck coming down from inland Misiones and leaving along Route 12 crosses Posadas’s camera-equipped access roads on every trip; the fine reaches the owner’s address weeks later. Looking up each plate at month end, with the per-source result stored, assigns the fine to the driver and covers the defence in time.

For a motorcycle delivery company or an urban service fleet, helmet and document fines fall on the rider; a monthly plate lookup, with the result stored, lets you deduct them from the right person before they pile up on the company’s plate.

How to integrate

The integration starts with one POST per plate, with the jurisdiction as an optional filter. Since courts answer at their own pace, the API accepts the job and delivers the result by status or webhook; store the idempotency key before sending, as the asynchronous APIs guide describes. The API page details access.

Limits and considerations

  • Fines on national and provincial routes outside the town limits are not municipal; the response names the authority of each.
  • Fixed-unit amounts are converted at the value current at the source; the final amount is set by the authority at the time of payment.
  • A source that does not answer is reported as such, never as an absence of infractions.
  • The API neither pays fines nor handles defences; it delivers information to decide.
