Istat Calabria SIRDAT (ROSS1000) is the Regione Calabria’s official online system used by accommodation providers to comply with mandatory tourism statistics reporting. The platform enables properties (hotels and extra-hotel accommodations) to register and submit daily tourist flow data (arrivals and departures), supporting the regional tourism observatory and national ISTAT statistical programs.

For PMS integrations, ROSS1000/SIRDAT is typically treated as a compliance destination: the PMS helps operators prepare and export the required daily movement data and property identifiers (e.g., CIR and, where applicable, CIN) so staff can submit them through the regional portal. The system also supports administrative communications such as declaring temporary opening/closing periods, improving data completeness and reducing manual errors for properties operating in Calabria.
