Curitiba's Central 156 citizen hotline, running since 1984, gained a geolocated smartphone app in 2019 for photo-attached requests and status tracking. Operated by the city's Institute for Smart Cities (ICI), the app now carries most contacts: in the first half of 2025 it handled 8.2 million of Central 156's 9.3 million interactions, versus phone, web portal and chat combined.

Run byInstituto das Cidades Inteligentes (ICI), operating Central 156 under contract to the Prefeitura de Curitiba since 1999

Scale🏙️ City-wide

📊 Impact

In H1 2025 the app handled 88% of Central 156's 9.3 million citizen contacts (8.2 million), up 22.7% from H1 2024's 7.6 million total and 32% from H1 2023's 6.3 million — official city report, published 24 July 2025.

🎓 Lesson

The 156 phone line and in-person Rua da Cidadania offices remain the fallback for citizens without smartphones. In March 2026 a Curitiba city councillor introduced a bill for a digital-literacy program for residents over 60, explicitly citing the risk that digitizing public services excludes citizens without training.
