Tarjeta Sanitaria expired?
Super helpful member
The Tarjeta Sanitaria is an important document, used to make appointments, identify you for Covid vaccinations etc.
Unfortunately there seems to be no system to remind you to renew it, so I suggest you have a look at the valid to date. Renewal is free and straightforward (bar my comments re understanding, below).
The only way to renew it is to make an appointment at the main Los Alcazares Centro de Salud, in my opinion the worst place I have found for not being Brit-friendly - particularly the jobsworth security guard who acts like he is general Franco!
The ladies on reception speak no English, so if your Spanish is not good think about taking someone to interpret.
