Italy's Alloggiati Web and the new CIN code, explained
If you host guests in Italy, you now have two separate compliance duties to keep on top of: you have to report each guest to the police, and you have to register the property itself. Both carry fines, and both became stricter recently. Here is what Alloggiati Web and the new CIN code ask of you.
Two obligations, not one
It helps to separate them from the start:
- Report the guest through Alloggiati Web, the State Police portal, for every stay.
- Register the property by obtaining a CIN, the national identification code, and displaying it.
The first happens for every guest. The second is a one-time setup per property that then has to be shown everywhere you advertise.
Alloggiati Web: reporting your guests
All accommodation providers, from hotels to short-term rentals, must communicate guest data to the local Questura (police headquarters) through the Alloggiati Web portal.
- What you report: full name, date of birth, nationality, and passport or ID document number for each guest.
- When: within 24 hours of arrival. For stays shorter than 24 hours, the report has to be made immediately, often interpreted as within about 6 hours.
The clock is tight, and it runs for every single arrival, including late and out-of-hours check-ins.
The CIN: registering the property
Since 1 January 2025, every tourist accommodation in Italy, including hotels, B&Bs, guesthouses and short-term rentals, must obtain a CIN (Codice Identificativo Nazionale), a national identification code.
Once issued, the CIN has to be displayed visibly at the property entrance and included in every online listing and advertisement, on Airbnb, Vrbo, Booking.com and your own website alike.
The penalties are significant:
- No CIN: fines from 800 to 8,000 euros.
- Failing to display or use the CIN correctly: fines from 500 to 5,000 euros.
Why this trips operators up
As with the rest of Europe, the difficulty is operational, not conceptual:
- Two parallel systems to satisfy, one per guest and one per property.
- A 24-hour (or 6-hour) reporting window that does not pause for busy weekends.
- The duty sits with you regardless of where the booking came from. The platform does not file the police report for you.
If you also operate elsewhere in Europe, you are now juggling Italy's Alloggiati Web alongside Spain's SES.Hospedajes and the Dutch Nachtregister, each with its own system and clock. We map the wider picture in Guest registration across Europe.
One flow, mapped to Italy
Obtaining and displaying your CIN is a setup task you do once. The part that repeats, reporting every guest to Alloggiati Web on time, is exactly what Guest OS is designed to take off your plate. By capturing guest identity once at check-in and submitting the required data automatically within the deadline, the police report stops being a daily race and becomes a background process, mapped to Italy's own requirements.
