Alloggiati Web: correcting or cancelling a sent form

A misspelt surname, a single digit wrong in a document number, or a guest deciding to stay two nights longer than planned. Sooner or later, you’ll realise you’ve made a mistake after the guest registration form has already been submitted, and the question is always the same: can I fix it?

Cancel before you send, not after

As long as the form hasn't been submitted, correcting it is straightforward. When entering data manually, the portal shows a summary of all forms before they are sent. If something doesn't look right, the "Cancel" button clears the data and lets you start again. If you are using a file, you can cancel the entire upload after processing, correct the file, and re-process it. This is the right moment to double-check everything, because once it’s gone, things change.

Once submitted, the form is set in stone. The guidelines from the Questura di Cagliari are crystal clear: the system does not allow you to edit data that has already been transmitted. If you’ve made a mistake, the only option is to resubmit the form with the correct details. There is no button on the portal to modify or withdraw a submission that has already been sent.

How to resubmit a form with errors

Essentially, a correction is just a new submission. You fill out the guest's form again with the right information and send it just as you did the first time, whether manually or via file. Before doing so, it’s worth checking what was actually sent: the "Analysis" section of the portal shows the names submitted that day, along with the time of submission. It’s the quickest way to see if the error involves just one person or the entire group.

This is where a limitation that catches many people by surprise comes into play. The portal only accepts today’s or yesterday’s date as the arrival date, so you must resubmit on the same day or, at the latest, the day after arrival. If you spot the error later, the corrected form cannot show the actual date. In that case, you should follow the instructions of your local Questura, writing to them to explain what happened while providing the guest's name and the date of the original submission.

The same advice applies if you accidentally submitted the same guest twice, or if you sent a form for someone who ended up not arriving. The portal doesn't offer a way to retract these, so it’s up to the local police headquarters to tell you if and how to record the change.

Check your work on the day

The "Analysis" section has a limitation you should know about before you actually need it: it only shows forms submitted on the current date. The next day, the names disappear, leaving only the receipt, which shows the number of forms sent but not who they were for. The portal’s FAQs state this clearly: you must verify submitted forms on the day they are sent.

This is why a simple habit can save you a lot of stress. At the end of the day, after your final submission, open the "Analysis" section and compare the names with your actual arrivals. An error found that same evening can be corrected with a new submission without any date issues. The same error found three days later, however, requires a letter to the Questura. It is also worth noting down every resubmission in your records, including the date and reason, along with any response from the police. Keep these notes alongside your receipts, which must be stored for five years.

If the guest stays longer

The length of stay you communicate is what the guest declares upon arrival, but this can change. For an extension of stay, the FAQs from the Questura di Siena suggest re-entering the data as if it were a new arrival, specifying the additional number of days the guest has declared. You should make this new submission as soon as the extension is decided, using an arrival date that the portal will accept.

For an early departure, however, there is nothing to be done. The same guidelines explain that the system does not provide a way to report a departure earlier than expected, and early departures should not be communicated. The form you already submitted remains valid for what was declared upon arrival.

When a booking changes

Changing booking dates is a standard part of the job, but how it affects your obligations depends on one detail: whether the data has already been sent or not. A submission that hasn't been sent yet is not a problem, as you simply prepare it with the dates valid at the time of sending. A submission that has already gone through, however, describes a stay that has since changed, and the correction follows the rules mentioned above.

On Roraima, this difference is clear. Data is only sent to the State Police after the owner has registered the guest's arrival, as explained in the article Alloggiati Web in Italy: when and how to report guests. Therefore, a booking that is moved or cancelled before arrival leaves nothing to rectify: communications still pending will either update or close automatically.

If the change happens after submission, the dashboard will show an entry saying "The communication to the authorities must be rectified" and will place the original data side-by-side with the current data, such as the stay dates and the number of people. The rectification remains an action for the owner to take on the portal, following the method indicated by the Questura, because a submission sent twice cannot simply be withdrawn. The advantage is having exactly what needs correcting right in front of you, without having to rely on your memory.

Errors worth preventing

The easiest way to avoid corrections is to avoid mistakes in the first place. Most errors stem from transcription: a name copied from a blurry photo, a nationality written exactly as it appears on a foreign document, or a town of birth typed from memory. These are the same errors that the portal sometimes rejects and sometimes lets through, provided the incorrect data is still technically valid.

This is why, on Roraima, guests enter their own details before arrival. The owner then checks the form, and every field is converted into the official table codes before submission. If data doesn't fit those tables, it stops the form and explains the issue in plain language, so the error is corrected when it’s easy to fix—before it’s sent. The most frequent errors and how to spot them are collected in our article on errors in guest forms.

Frequently Asked Questions

Can I modify a form already sent to Alloggiati Web?

No. The portal does not allow you to edit transmitted data. In case of an error, you must resubmit the form with the correct details. The new submission must respect the arrival date accepted by the portal, i.e., today or yesterday; beyond that limit, you must contact the Questura.

How do I cancel a form sent by mistake?

There is no function in the portal to withdraw a submitted form. For a duplicate submission or for a person who did not arrive, it is best to write to the relevant Questura, providing the guest's name and the date of submission, and follow their instructions.

What should I do if the guest extends their stay?

You should resubmit their details, as if it were a new arrival, indicating the additional days the guest has declared. Early departures, however, do not need to be communicated.

When must guests be reported?

In Italy, within twenty-four hours of arrival, which is reduced to six hours if the stay is less than twenty-four hours. The time is counted from the guest's actual arrival, as explained in the article Alloggiati Web in Italy: when and how to report guests.
