Biometric User Registration

Since 2020, biometric registration is mandatory for buying a SIM card in Brazil. This includes:

  • Valid passport
  • Photo and fingerprint taken in-store
  • CPF (Brazilian Tax ID) – not required for tourists, but some vendors may ask

The registration process typically takes 10–15 minutes.

What to Expect When Buying

  • Purchase at official stores, not kiosks, for proper activation
  • SIM card packaging includes a PIN/PUK and a phone number
  • Some stores may charge a setup fee, but often this includes a basic data plan

Device Registration

There’s no IMEI registration requirement for tourists. However, if you plan to stay over 90 days, it’s advisable to register your device with Anatel, Brazil’s telecom authority.
