Overview of Italy’s National Identification Code, a self-check checklist and a printable A4 sign. Everything stays on your device.
The Codice Identificativo Nazionale is assigned via the Ministry of Tourism’s BDSR (art. 13-ter of Decree-Law 145/2023, converted by Law 191/2023). It identifies accommodation facilities and units used for short-term or tourist lettings in Italy.
Purely free hospitality is outside the obligation (Ministry FAQ). A regional/provincial code does not replace the CIN — you must still obtain and display both where required.
For units used for short-term or tourist lettings (business or not): working combustible gas and carbon monoxide detectors, plus compliant portable extinguishers (at least one per 200 m² or fraction, and at least one per floor; min. 13A / 6 kg or 6 l per Ministry FAQ). Detector exemption if there is no gas system and CO risk is certainly excluded. Hotel/B&B-type facilities follow other safety rules.
National rules apply from 2 November 2024; sanctions from 2 January 2025 (Ministry FAQ updated 11 May 2026).

Local structural check based on the composition documented by the Autonomous Province of Trento (IT + ISTAT + classification + string). The Ministry does not publish an official regex — this does not replace BDSR CIN search.
