Alloggiati Web ("Servizio Alloggiati") is the official Italian State Police (Polizia di Stato) online service used by accommodation providers to transmit guest identity details to the competent local police headquarters (Questura) in compliance with Italian public security regulations. Hotels, B&Bs, vacation rentals and other lodging facilities must send the details within 24 hours of arrival (or immediately for stays under 24 hours) using this portal.

For PMS integrations, Alloggiati Web is typically handled as a legal compliance workflow: the PMS exports guest data in the required format, maps it to official coding tables, and supports operator submission through the Alloggiati Web portal (or via certified/approved automated flows where available). The service provides manuals, FAQs, regulatory references, credential recovery, and downloadable coding tables to standardize data entry and reduce errors, helping properties stay compliant and avoid penalties.
