'Prenotazione' — pre-no-ta-TSYO-ne. Six syllables; 'zi' sounds like 'ts'. Stress on the fifth syllable.
Say this at a hotel, car rental, or tour office when you have a booking confirmation but the staff cannot find your reservation in their system. Always carry your booking reference.
'Non si trova' (cannot be found) is the impersonal reflexive construction — literally 'does not find itself'. This is more natural in Italian than the passive 'non viene trovata'. Having 'nel sistema' (in the system) adds specificity. Always have a printed or screenshotted booking confirmation as backup.
Ecco il numero di conferma.
Here is the confirmation number.

Italian hotel reservation systems, particularly in smaller family-run hotels (alberghi a gestione familiare), can have manual booking errors. Always carry a printed or screenshot copy of your confirmation email. Booking.com and Airbnb have 24-hour support to mediate in these situations.
