Background
The BDSR (Banca Dati Strutture Ricettive) is Italy's central accommodation database, administered by the Ministry of Tourism as the backend registry for the CIN (Codice Identificativo Nazionale) short-term rental registration system. It serves as Italy's Single Digital Entry Point (SDEP) layer under the EU STR Regulation, collecting property details, host information, and registration status for all accommodation operators .
The BDSR was built to replace fragmented regional accommodation registers, which previously made cross-regional enforcement and taxation monitoring impossible. Platforms connecting to the BDSR API can validate CIN codes in real time, though the connection API was still being rolled out to smaller platforms in early 2026.
Italy's BDSR is one of the more operationally advanced SDEP implementations among EU member states. The European Commission is using it as a reference architecture for member states still building their national portals, particularly those without legacy accommodation registration systems.
