Italy: the CIN short-term-rental registration number
Italy requires every short-term-rental and tourist accommodation to obtain a Codice Identificativo Nazionale (CIN) from the Ministero del Turismo and display it on every listing.
What the CIN is
The Codice Identificativo Nazionale (CIN) is Italy’s single national identifier for accommodation. It was introduced by Article 13-ter of Decreto-Legge 145/2023 and is issued through the Ministry of Tourism’s BDSR (Banca Dati Strutture Ricettive). It replaces the patchwork of regional codes (CIR) with one number that must appear on every rental advertisement, including on platforms such as Airbnb and Booking.
Where to register
You apply on the BDSR portal at bdsr.ministeroturismo.gov.it, signing in with SPID or CIE (your Italian electronic identity). The CIN is generated automatically once your declaration is filed and your cadastral and safety data are recorded.
What the number looks like
A CIN looks like IT058091-A1-00000001: the prefix IT, a 6-digit ISTAT province-and-commune code, a 2-character ISTAT category code, and up to 8 random alphanumeric characters, separated by hyphens. The format is defined in the ministerial decree of 6 June 2024 (Prot. n.0016726/24). There is no checksum — the trailing block is a random string.
What you need
SPID or CIE to sign in; the property’s cadastral data (foglio, particella, subalterno); and a self-declaration that the mandatory safety requirements are met — smoke and carbon-monoxide detectors and a portable fire extinguisher.
Deadlines and penalties
The CIN rules took effect on 2 November 2024, and penalties for operating without one apply from 2 January 2025. There is no periodic renewal: the CIN lasts until the activity ends, though the authority can revoke it. Displaying a CIN is now a precondition for advertising on any platform.
Check your number
Paste your Italy registration number into the helper for a client-side format check that runs entirely in your browser. Our tool checks the CIN format only — it confirms the shape matches the official decree, not that the number is actually registered. Use the BDSR public lookup to verify a real CIN.
