- Online, via ePortugal (public services portal) — if you are 25 years old or older, you need the Chave Móvel Digital (Digital Mobile Key) or a card reader, and you do not need to change data or photo.
- In person — book an appointment on Siga (siga.gov.pt or SigaApp) and go to a Registration Office, Loja do Cidadão (Citizen Shop) or a consulate.
- Bring your current Cartão de Cidadão (Citizen Card). In the in‑person service they take the photo and collect your signature on the spot.
- The price depends on the processing time and the location; online renewal is cheaper. Check the current amount at the official source.
You can renew before it expires — you do not have to wait for it to expire.
