Alloggiati Web: within how many hours to submit, common mistakes and penalties

Submitting guest data through Alloggiati Web is one of the trickiest obligations for anyone running a hotel, a B&B or a short-term rental: it has a very tight deadline and, if you miss it or get it wrong, the consequences can be serious. In this guide we look at within how many hours the report must be made, the most frequent mistakes and what you risk in case of omission or delay.

What Alloggiati Web is, in brief

Alloggiati Web is the State Police service through which accommodation facilities report to the Questura the details of the people they host, for public-security purposes (art. 109 of the TULPS). It is not a statistical or tax report: its purpose is to let the authorities know who is staying at the property. That is precisely why the timing is strict.

Within how many hours the report must be submitted

The general rule is clear: the data must be transmitted within the 24 hours following the guest’s arrival. For very short stays — no longer than 24 hours — the report must be made even sooner, as provided by the official guidance. Since there have been clarifications on this point over time, always check the current timing directly on the Alloggiati Web portal.

The count starts from arrival, not from the booking: it is the check-in moment that starts the clock. That is why collecting documents at check-in, and not “later”, is the safest way to stay within the deadline.

Who must report and for which guests

The obligation applies to all accommodation facilities, including non-hotel ones and short-term rentals. The data of all the people hosted must be reported, not only of whoever booked.

• All types of facility: hotels, B&Bs, guesthouses, holiday homes, short-term rentals.
• All guests actually hosted, group members included.
• For families and groups there are dedicated methods (head of family or group leader with the related members).
• You need the credentials issued by the Questura and a valid digital certificate to access the portal.

The most common mistakes

Most problems arise not from complicated cases, but from oversights that repeat. Here are the ones we see most often.

• Submitting late, beyond the hours allowed from arrival.
• Forgetting a group member or a minor.
• Mis-transcribing the document details (number, type, place of issue).
• Confusing Alloggiati Web with the ISTAT survey or the tourist tax: they are different obligations, to different bodies.
• Not downloading and keeping the submission receipt.
• Realising too late that the credentials or digital certificate have expired.

What you risk: missing or late reporting

Reporting hosted guests is a public-security obligation set by art. 109 of the TULPS. Omitting it, or submitting it late, exposes you to penalties: for the exact amount and nature it is always best to refer to official sources, since the matter is sensitive and may be updated. The practical point is simple: it is not something to improvise, and it is among the things the authorities check.

Beyond the penalty itself, systematic delays or inconsistent data can attract checks on the property’s other obligations too. Keeping Alloggiati Web in order is therefore also a way to stay calm about the rest.

How never to get it wrong: collect once, submit on time

The trick is to take the memory factor out of the equation. If at check-in you already collect the document data in a structured way — even having the guest enter it from their own phone — the report becomes a quick, on-time step, instead of an end-of-day scramble.

HotelOnlineAI is built for this too: it collects guest data at check-in (for example via QR, in the guest’s language) and prepares it for submission to Alloggiati Web within the deadlines, reducing delays and transcription errors. It does not replace your Questura credentials, but it saves you from rebuilding everything by hand and from forgetting anyone. Want to see it on your property? Request a free demo.

In summary

Alloggiati Web must be filled in carefully and, above all, on time: the general rule is submission within 24 hours of arrival, with tighter times for very short stays — always check the current timing on the official portal. The most costly mistakes are being late, forgetting a guest and getting the document data wrong. Since it is a public-security obligation, missing or late reporting is penalised: the best way not to risk it is to collect the data at check-in and submit it right away, keeping the receipt.
