- The PIN, PUK and cancellation codes are in the code letter you received with the Cartão de Cidadão (Citizen Card).
- If you lost the letter, request a new one in person at an IRN (Institute of Registries and Notaries) counter, Espaço de Registos or Loja do Cidadão (Citizen Shop) — you cannot retrieve the codes online.
- Without the authentication PIN you cannot use the card reader to access services — but you can use the Chave Móvel Digital (Digital Mobile Key) as an alternative.
