Não Me Perturbe SMS Verification

The Não Me Perturbe SMS verification code proves that the Brazilian line you want shielded from telemarketing really is yours; here is how the process works.

Não Me Perturbe (Do Not Disturb) is a free Brazilian platform that telecom operators set up in 2019 at the direction of the regulator Anatel. It lets consumers block sales calls from carriers such as Claro, Vivo, TIM and Oi, as well as banks like Banco do Brasil, Itaú and Nubank. Sign-up asks for your name, CPF and e-mail, and a 6-digit SMS code sent to the number in each block request confirms you own that line.

Here the SMS code is not a routine sign-up step but proof that you own the number being blocked. A virtual number therefore only makes sense if that number itself is what you want to protect, for example a Brazilian line you keep long term for business. A short-lived number cannot shield your personal phone, and because a CPF is required, the service is realistically for people registered with Brazil's tax authority.

A block can take up to 30 days to take effect, and it only covers participating carriers and banks; for other companies you need to sign up with your state's Procon list separately. Debt-collection and fraud-prevention calls may fall outside its scope. If you switch lines, register the new number too, and never share the password of the account you opened with your CPF.
