How do I register with the SNS and get a número de utente?
Every legal resident (D7, D8, D2, work, student, family reunification, EU/EEA/CH) has the right to use the public health system. The key is the número de utente — your SNS user number.
Where: the Centro de Saúde for your address (the system is geo-assigned).
Documents: residence permit + ID + NIF + full address.

The honest caveat for 2026: Portugal has a shortage of family doctors — by late 2025 about 1.56 million residents had no assigned médico de família. Without one, people use SNS 24 (the phone/online line), the consulta aberta (open walk-in consultation) and emergency services. This is exactly why most expats keep private insurance alongside SNS rather than instead of it.

What is the número de utente and why do I need it?
It is your SNS (public health service) user number — the key that lets you register with a family doctor and use public healthcare as a resident.
Who can use public healthcare in Portugal?
Every legal resident — D7, D8, D2, work, student, family reunification, EU/EEA/Swiss — has the right to use the SNS once registered.
Do I still need private insurance?
It is optional once you are in the SNS, but many expats keep private cover for faster specialist access and shorter waits. Costs are indicative — compare providers.
