For long-distance calls within Brazil, a zero ( 0) must be dialed first, then a carrier selection code (for example, 21 for Embratel and 41 for TIM Brasil), then the two-digit area code, then the local number. (There is an exception for some iDEN mobile lines operated by Nextel, which are eight digits long and start with 7 and disestablished in 2018.)Īrea codes have two digits, and are often notated between parentheses: (aa) nnnn-nnnn. Initial digits 6 through 9 are reserved for mobile numbers, but as of 2017 all mobile numbers in Brazil start with the digit 9. Landline numbers start with digits 2 through 5. Mobile numbers share the same geographic area codes as landlines, but the first digit differentiates them. Local phone numbers in Brazil observe an eight-digit pattern ( nnnn-nnnn) for landlines and nine digits ( nnnnn-nnnn) for mobile phones. The area codes are distributed geographically, citing the main cities in each area. This article contains a list of area codes in Brazil for telephone dialing.
