To be able to register for public healthcare in Spain, you will first need to get a social security number. Once you have received your social security number take it to your local health centre to register and apply for a health card (tarjeta sanitaria individual or TSI).   The Primary Care Centers (Centers d’Atenció Primària or CAP) are the first point of access to health care in Barcelona, here you can book regular appointments with the General Practitioner (GP). The CatSalut will assign all citizens a specific CAP based on their address. However, if you require urgent medical care you should visit the Continuous and Urgent Care Center (Center d’Urgències d’Atenció Primària) which are open 24 hours a day, including weekends and public holidays.
