The CIN: Italy's national code for short-term rentals
Every holiday let, short let and accommodation business in Italy needs a CIN, the national identification code issued through the Ministry of Tourism's BDSR database. The code goes outside the building the flat or property is in, and in every listing, wherever it is published. Renting out without one is fined €800 – €8,000, and not showing it €500 – €5,000 per unit.

Who needs a CIN
The CIN (codice identificativo nazionale) is assigned to every home let for tourist purposes, every short let and every hotel or non-hotel accommodation business. The rules apply from November 2, 2024, and the Ministry set January 1, 2025 as the deadline to have the code.
Where a region or autonomous province already issued its own identification code, it does not disappear: the region converts it into a CIN by adding a prefix the Ministry supplies. A host whose region has not done so requests the CIN directly.
How to request it
The request is made online on the BDSR, the Ministry of Tourism's national database of accommodation and short lets. It comes with a self-certified statement (dichiarazione sostitutiva, made under criminal liability for false statements) giving the property's land-registry data and, for a landlord, confirming the safety equipment below.
Where to show it
The CIN goes outside the building the flat or property is in, and in every listing, wherever it is published. Agents and platforms that publish the listing must show it too.
Not showing it is fined €500 – €5,000 per unit, and the listing is taken down.
Safety equipment
Every let unit, whether or not it is run as a business, must have working detectors for combustible gas and carbon monoxide, and portable fire extinguishers: one for every 200 m² and at least one per floor. A missing device is fined €600 – €6,000 for each violation found.
A unit run as a business must also meet the safety requirements for its installations under national and regional law.
When it counts as a business
Short letting is presumed to be a business from the 2026 tax year, when three or more flats are let short-term in the same tax year. A host letting as a business must file a SCIA (certified notice of starting an activity) with the municipality's SUAP office; doing without one is fined €2,000 – €10,000.
Fines and who applies them
The municipality where the property is located checks and fines, through its local police, and keeps the proceeds. A region that already fines the same conduct under its own law takes precedence over the national fines.
