Istat Sardegna (ROSS 1000, the new version of the SIRED application) is the Regione Autonoma della Sardegna platform used by accommodation providers to comply with mandatory statistical reporting obligations. The system supports the collection and submission of guest movement and accommodation statistics required by regional/national statistical frameworks (ISTAT), with authenticated access and full access traceability in line with GDPR.

For PMS integrations, Istat Sardegna is typically used as the compliance endpoint for periodic transmission of arrivals/presences and related structure data, reducing manual entry and improving data accuracy. The platform is accessed by authorized users (usually the property manager/legal representative), and operational support is handled via the regional help-desk portal (INTERACTA) and official guidance/FAQs referenced on the login page.
