LOCAL DIALING The format for a local phone number is ''nnnn-nnnn'', where the first digit identifies the service associated with the phone number:
Some localities still use a seven-digit local number, which is being phased out. PUBLIC UTILITY The format for public utility service phone numbers is ''1nn''. It includes the emergency services, some of which are:
DISTANCE DIALING The format for a long-distance phone number is ''(0aa) nnnn-nnnn'', where ''aa'' is the area code and ''nnnn-nnnn'' is the local phone number. Area codes are distributed geographically. See the List Of Brazilian Area Codes for a full list. To dial a long-distance number within Brazil, you need to use a Carrier Selection Code , to chose which long-distance carrier will be used. It is specified before the area code, so you should dial ''0-xx-aa-nnnn-nnnn'', where ''xx'' is the two-digit carrier selection code. Because of that, sometimes long-distance phone numbers are represented as ''(0xxaa) nnnn-nnnn'', with literal ''x'' characters as placeholders which the caller will replace a carrier code. COLLECT CALLS Local Collect Call s are dialed with the ''9090'' prefix, so to dial ''nnnn-nnnn'', you would use ''9090-nnnn-nnnn''. Long-distance collect calls use the ''90'' prefix instead of the long-distance ''0'' prefix, so to dial ''(0aa) nnnn-nnnn'', you would use ''90-xx-aa-nnnn-nnnn''. NON-GEOGRAPHIC NUMBERS Non-geographic numbers have a three-digit prefix and a seven-digit number. They are usually represented as if the leading ''0'' prefix were part of the three-digit prefix (like with long-distance numbers), resulting in the format ''0ppp-nnn-nnnn''. The currently allocated prefixes are:
INTERNATIONAL CALLS Outbound international calls use a ''00'' prefix, followed by the carrier selection code and the International Telephone Number . For instance, to call the international telephone number ''+cc-aa-nnnn-nnnn'', you would use ''00-xx-cc-aa-nnnn-nnnn''. Since international telephone numbers can have up to 15 digits, the maximum number of digits to be dialed is 19. Inbound international calls use ''+55-aa-nnnn-nnnn'' as the international telephone number. This must be preceded by a country-specific International Call Prefix . A NOTE ABOUT MOBILE TELEPHONY IN BRAZIL Mobile phone numbers are prefixed with the digit '7', '8' or '9'. '7' is used mainly for radiophone use ( IDEN technology), but there is an exception in São Paulo area (11), where CDMA and GSM mobile phones can also start with '7'. Numbers with an '8' are always GSM Mobiles, while '9' can be mostly analogue ( AMPS ), TDMA and CDMA mobiles. The prefix number in mobile telephony is related to the license the carrier has. On newer licenses, use of the '8' digit is mandatory, while the previously state-owned mobile operators always uses '9' (or '7', in some cases in São Paulo area). Some GSM mobiles can be prefixed with a '9' because the now privatized operators decided to overlay using this technology. Mobile phone numbers generally have eight digits. Exceptions exist in Brasília . REFERENCES
