What is the National User Registry (RNU)?
The RNU is the national database used to identify people who access the SNS. Registration provides a Número Nacional de Utente (NNU), commonly known as the SNS user number or Número de Utente.
A user number identifies a person within the healthcare system. However, having a user number does not automatically mean that the SNS will cover all healthcare costs, or that the person will be assigned a family doctor.
