The Brazilian telephone numbering plan uses a two-digit area code plus eight-digit local phone numbers for landlines and nine digits for mobile lines.Public utility services use short phone numbers (usually three digits), always starting with 1.
As established by ANATEL, the Brazilian federal telecommunications regulatory agency, the format for a local phone number is nnnn-nnnn (eight digits) for landlines, and nnnnn-nnnn (nine digits) for mobile lines. The first digit identifies the service associated with the phone number:
0 is reserved for long-distance calls and cannot be used as a local initial digit (see below).
Until 2008, the initial digit 6 was used for landlines in some parts of São Paulo and neighbouring cities in area code 11, but Anatel demanded that 6 was to be released for mobile use. Fixed-line numbers starting with 6 in that area were gradually changed during 2008 to new prefixes starting with 2. In other areas of Brazil, the initial digit 6 was not in use at that time, so no change was necessary.
Until 2005, some localities still used a seven-digit local number (nnn-nnnn). Until the 1990s, there were also certain regions with three-digit area codes and five- (n-nnnn) or six-digit (nn-nnnn) phone numbers. Even shorter numbers used to exist in previous decades, especially in small towns and before direct distance dialing became universal.
Numbers starting with 300n and 400n are reserved for a special case of non-geographic numbers (see below).
Numbers starting with 1700 are used by some Internet Service Providers (ISPs) to provide dial-up Internet access. Those ISPs have special pricing agreements with local landline operators and customers are charged less than the price of regular local calls when calling such dial-up access numbers.
