Central 1746: Rio's Municipal Service Requests, Open Since 2011
Rio has taken municipal service requests through the single 1746 channel — phone, web, app and messaging — since March 2011, covering around 1,500 services. A 2018 decree caps resolution at 30 days and makes the city ombudsman a formal second level when a deadline, an answer or its quality fails; the ombudsman's public panels grade each agency against targets of over 90% answered and under 10 days. Per-service deadlines are published too, and some are long: street-tree pruning is quoted at up to 240 days. Every ticket since launch is published on data.rio — but under CC BY-ND 3.0, a no-derivatives licence applied to a dataset.
More than 15 million requests in the channel's first ten years, growing from about 200 services at launch to roughly 1,500 (Prefeitura do Rio, March 2021 — operator figures).
🎓 Lesson
Publishing the tickets does more accountability work than the deadline does. Rio's 30-day cap and agency scorecards carry no penalty, but the open records let local reporters show the Environmental Patrol answering 9.8% of its 1746 queue after a support contract lapsed — and a no-derivatives licence is exactly the wrong clause to put over data meant to be counted.
