CIN code for short-term rentals: what it is and how to get it

The CIN (National Identification Code) is a unique mandatory code for every property used for short-term rentals in Italy. Introduced by the 2023 Anticipi Decree, it unified the previous regional codes at national level and must be displayed in every OTA listing. This guide covers who must request it, how to obtain it, where to display it, and how to manage it across multiple properties.

In sintesi

What it is: the CIN is a unique identification code assigned by the Italian Ministry of Tourism to every property used for short-term rentals in Italy.

Who requests it: the holder of the rental activity, usually the property owner. The property manager can support the owner or act under delegation.

Where to display it: in every OTA listing (Airbnb, Booking, Vrbo, etc.), on the PM's website, in promotional materials.

Penalties: applied for missing CIN or failure to display it. OTAs can suspend listings without a CIN.

What the National Identification Code is

The CIN (National Identification Code) was introduced by the 2023 Anticipi Decree (D.L. 145/2023) to register and track Italian short-term rental accommodation. It is a unique code assigned to each individual property by the Italian Ministry of Tourism through a dedicated portal.

Before the CIN, each Region had its own system (CIR Lombardia, CIPAT Trentino, codes from the Autonomous Province of Bolzano, etc.). This fragmentation made national oversight difficult and created confusion for multi-region operators. The CIN unifies registration at central level, though it does not automatically eliminate existing regional codes (check with your accountant (commercialista) which ones you still need to maintain in your reference Region).

Who must request the CIN

The CIN is mandatory for every property used for short-term rentals, regardless of tax regime or management model:

Private owners who rent directly, even occasionally, on Airbnb or Booking
Property managers operating revenue share or subletting on behalf of third-party owners
Hosts of B&Bs, room rentals, vacation homes, small residences
Structured property management companies

The request comes from the holder of the activity (usually the owner), but the property manager can proceed under delegation from the owner.

How to obtain the CIN

The full procedure has 4 steps (verify the up-to-date details on the Italian Ministry of Tourism portal at the time of application):

1. Check the requirements
Confirm the property qualifies as a short-term rental (contracts up to 30 days, without hotel services). Gather the owner's personal data, the property's cadastral data, and the full address.
2. Access the Ministry of Tourism portal
Access requires the SPID or CIE of the applicant. If you proceed under delegation from an owner, prepare the necessary documentation.
3. Fill out the request
Enter the owner's personal data, the property's cadastral data, and the required information about the rental activity.
4. Receive the CIN and update your listings
Enter the obtained CIN in the dedicated field on every OTA listing (Airbnb, Booking, Vrbo) and on your own website. Keep the assignment receipt for any future audits.

Where to display the CIN

The CIN must be visible in every context where the property is promoted:

Listings on Airbnb (dedicated field in the listing section)
Listings on Booking.com (regulatory information field)
Listings on Vrbo and other OTAs
Property manager's or owner's website
Promotional materials and guest communications

If you manage multiple properties, it's easy to lose track of which ones have the CIN correctly displayed across all channels. A dedicated system (see below) eliminates this risk.

Frequently asked questions about the CIN code

What is the CIN (National Identification Code)?

The CIN is a unique identification code assigned by the Italian Ministry of Tourism to every property used for short-term rentals in Italy. It was introduced by the 2023 Anticipi Decree (D.L. 145/2023) to register and track accommodation across the country. The CIN replaces and unifies prior regional codes (CIR Lombardia, CIPAT Trentino, and similar).

Who must request the CIN?

The CIN is mandatory for every property used for short-term rentals, regardless of the owner's tax regime or management model. Required to apply: private owners renting directly, property managers operating on behalf of third parties, B&Bs, room rentals, vacation homes, residences. Even a single property rented occasionally on Airbnb or Booking must have its own CIN.

Where must the CIN be displayed?

The CIN must be displayed visibly in every context where the property is promoted: OTA listings (Airbnb, Booking, Vrbo, etc.), property manager website, promotional materials, guest communications. OTAs provide a dedicated field for entering the CIN for each listing.

Does the property manager or the owner request the CIN?

The CIN request belongs to the holder of the rental activity, generally the property owner. However, the property manager can support the owner through the procedure, gather the required documents, submit the request on the owner's behalf under delegation, and manage the code update across OTA listings. In Dott.House the CIN is a dedicated property-level field, always visible and editable.

What happens if I don't have a CIN?

The absence of a CIN exposes you to administrative penalties under the regulations. In addition, OTAs may suspend or remove listings that don't show a valid CIN. It is therefore essential to obtain the CIN before publishing the listing, and to keep it up to date on the platforms. For exact penalty amounts and adjustment timelines, refer to communications from the Italian Ministry of Tourism or to your accountant (commercialista).

How do you manage the CIN across multiple properties?

Each property has its own CIN. For operators managing many units (property managers, multi-property owners), tracking CINs in Excel or in individual listings quickly becomes complex. Dott.House lets you record the CIN as a structured field for each property, export it in tax reports and owner statements, and trigger alerts when a property has no CIN.

Is the CIN the same as the CIR (Regional Identification Code)?

No. The CIR was a regional code (e.g. CIR Lombardia, CIR Lazio, CIR Toscana) introduced by individual Italian Regions for accommodation in their territory. The CIN is the unified national code, introduced centrally by the Italian Ministry of Tourism. In many cases the CIN sits alongside or replaces the prior CIR. Check with your accountant (commercialista) or on the relevant regional portal which codes you must keep active.
