Brazilian mobile numbers are 11 digits: 2-digit area code + 9 + 8 digits. Under Anatel's numbering rules a 9 right after the area code marks a mobile (SMP) number. Numbers are portable, so the number doesn't tell you the current operator.

Carriers & prefixes

Mobile prefixes by carrier.

Number portability applies — a prefix only shows the original carrier.

Porting rules in full

Porting is available (portabilidade numérica): you keep your number when you switch, you apply to the operator you are moving to, and Anatel requires it to be completed within 3 working days. Mobile numbers can only move within the same area code (DDD).

SIM cards & keeping a number

Every Brazilian line must be registered to an identified person (Law 10.703/2003). Foreigners can use a passport, though some carriers’ apps only accept a CPF tax number, so activation may need a call or a store visit. Prepaid lines stay active through top-ups; lapsed lines are restricted first, then cancelled.

Price
Depends on top-up
Keeping the number
Claro (official): once the last top-up’s validity ends, data and calls stop; 90 days later without a top-up the line is cancelled; after 180 days cancelled the number may be reassigned. TIM is similar and can be recovered by topping up within 180 days of cancellation.
ID check
Passport or CPF; TIM’s app needs a CPF, but foreigners can call *144 to activate with a passport
SMS & calls
A normal Brazilian number

Pros

  • Rules are clearly published by the carriers

Watch out

  • Service stops as soon as validity ends
  • Activation is awkward without a CPF
