RNU — Registo Nacional de Utentes (national patient register)
The database that holds your details as a patient of the public health service: your utente number and its status, address, phone number, which health unit you are registered with and whether you have a family doctor. The address and phone number used to call you in for an appointment or a vaccination also come from it.
Where you come across it. After getting a residence permit, moving house or changing your phone number; the text message "se é residente atualize os seus dados no RNU" is a request to update your details here.
Out-of-date details in the register are grounds for moving a patient to "waiting" status and giving their place on the doctor's list to someone else. You update your details at your unidade de saúde, bringing your passport, residence permit, NIF, NISS and proof of address.
