SIM issuance and activation using CPF and gov.br

Brazil has more than 260 million active cellular lines, all tied to CPF records. The CPF serves as the unique identifier for SIM card activation. Authentication through gov.br credentials strengthens digital verification for new activations and portability requests. The customer initiates a SIM registration and activation request through the telecom service provider's app or website and verifies identity through gov.br. This ties the activation to the correct person and reduces risks, such as identity impersonation and fraudulent activations.
