Local dialing

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 digits of the local number identify the service associated with the phone number: *''100'' to ''199'': special short

became universal. In the late 1990s, the 7-digit landline numbers beginning with ''9'' in the area of DDD 11 also had their prefixes changed, and their numbers were replaced in most cases by prefixes beginning with ''69'' (now ''29'') or ''64'' (now ''24'') in the cities of São Paulo and Guarulhos respectively. Landlines using prefixes beginning with ''8'' and ''7'' had their prefixes changed up to 2000 and 2001 respectively for 8-digit numbers, and new area codes 22, 28, 64, 66, 87, 88, 89, 93, 94, 97 and 99 are included at this time. Until 2005, some localities still used seven-digit local numbers (''nnn-nnnn''), such numbers being changed to eight digits (''nnnn-nnnn''). Except in the case of the states of

, the numbers of 7-digit landlines were given the number ''3'' preceding the old number, and the numbers of 7-digit mobile phones were given the number ''9'' preceding old number between late 90's until the inclusion of the ninth digit. In the state of Rio de Janeiro, only the 7-digit numbers beginning with ''3'' and ''8'' received the 3 preceding the old number, while the other numbers received the number ''2'' preceding the old number. In the country region and litoral of the state of São Paulo, in many cases the old prefix of 7-digit numbers have been completely changed, but this numbers standardized with an 8-digit number starting at ''3'' in landlines and ''9'' in mobiles until the inclusion of the ninth digit. In the Greater São Paulo and neighborhood cities using DDD 11, the cities today uses numbers initializing with ''2'', ''3'', ''4'' or ''5'', with the prefixes started in ''2'' are used mainly in

and neighbouring cities in area code ''11'', but Anatel required that ''6'' 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 because at this time landlines used prefixes beginning with ''2'', ''3'' or ''4'' outside the Greater São Paulo region. Exceptionally, at the beginning of the 2010s, cell phones with a prefix starting at 5 were enabled in Greater São Paulo, and in this transition period, which anticipated the inclusion of the ninth digit (9) preceding the old cell phone numbers, the telephony used intercept messages to indicate that calls to such numbers were being directed to mobile phone numbers. Today, landline numbers usually use the number ''3'' at the beginning of the number. The use of the initial digit ''2'' is occasional except in Greater São Paulo and the

. 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. Local directory assistance can be obtained by dialing ''102'', but the service is charged as a regular local call in most instances except from payphones. However, all local landline telephone companies offer on-line directory inquiries on their Web sites. Mobile lines are not available for inquiry, for privacy and security reasons.


Mobile telephony

Mobile phone numbers in Brazil are assigned the same geographic area codes as fixed lines, according to the subscriber's place of residence or most frequent use. Until the inclusion of the ninth digit, mobile phone numbers start with the digits ''6'', ''7'', ''8'' or ''9''. These initial digits are known to the public, so one always knows beforehand if one is calling a fixed or a mobile line. After replacing the landline numbers that started in ''7'' in 2001 (with 7 or 8-digits in Greater São Paulo and 7-digits in other regions), these numbers were initially reserved exclusively for radiophone use (

technology), but soaring demand for new mobile numbers eventually forced unused number ranges starting with ''7'' to be released for general mobile use. Historically, at the time mobile numbers had seven or eight digits, the higher ranges of the ''9'' initial digit (''96–99'') were originally assigned to the old state monopolies before the privatization of Brazil's telephony system, and later to their privatized direct successors. To create a competitive market, later the Brazilian government auctioned further mobile service licenses, filling the available number ranges backward – first with the lower ranges of ''9 (91–95)'', then ''8'', and so on. As a consequence, in the beginning ''9'' (today ''99'') was more commonly assigned to mobile operators that used older technologies such as AMPS (analog), TDMA and

licenses. Now GSM is universally adopted by Brazilian mobile operators and, combined with number portability and the inclusion of a ninth digit to the left (see below), this distinction is no longer observed or meaningful.


Ninth digit for mobile numbers

Brazilian mobile phone numbers always have nine digits now, but seven digits were usual in the first years, then eight digits became the standard for several years. The last area code to convert fully from seven to eight digits was ''61'' (comprising the national capital city,
Brasília Brasília ( ; ) is the capital city, capital of Brazil and Federal District (Brazil), Federal District. Located in the Brazilian highlands in the country's Central-West Region, Brazil, Central-West region, it was founded by President Juscelino ...
, and neighbouring areas), in 2005. However, the popularity of multiple- SIM mobile phones in Brazil makes the country have more active mobile lines than inhabitants (as of November 2016, 248 million vs. 206 million), and by 2010 the country's most populous and economically important area code, ''11'' of metropolitan

(an area where over 20 million people live), was getting close to exhausting its available mobile numbers. Overlays and extra area codes were considered, but deemed confusing and impractical for local conditions. So, on 10 December 2010, ANATEL announced the inclusion of a ninth digit (in the format ''9nnnn-nnnn'') to mobile phone numbers used in the

metropolitan region (area code ''11''). This change was meant to increase the numbering capacity in metropolitan São Paulo from 44 million to 370 million, thereby eliminating the perennial shortage of available numbers in that area. Telecom providers would have 24 months to implement the ability to dial a new digit to the left of all cell phone numbers of area code ''11'', but the measure ended up being implemented a few months ahead of that initial schedule, on 29 July 2012. On that date, the digit ''9'' was added to the left of all existing mobile numbers in the ''11'' area code, regardless of their former initial digits. So, for example, mobile number ''(11) 6010-2030'' became ''(11) 96010-2030''. To standardize the mobile numbering plan in Brazil, ANATEL started gradually rolling out the change to nine digits in other area codes and

, corresponding to area codes ''41'' through ''55'') did so on 6 November 2016. Initial digits ''6'' through ''8'' remain reserved for mobile lines, but as of September 2020 all mobile numbers in Brazil still start with ''9'' after the ninth digit was added, and it was not yet necessary to use the other reserved initial digits. Landline numbers (starting with ''2, 3, 4'' or ''5'') and trunked radio mobile telephony (

) numbers were not changed and remained with eight digits. As iDEN numbers had the same format as the former 8-digit regular mobile numbers, and some old 8-digit standard mobile numbers also used the initial digit ''7'' of iDEN numbers, some confusion happened for some time, with people adding an initial ''9'' when calling iDEN numbers, which would not allow the call to be placed. This is no longer a problem, as iDEN service was discontinued on 31 May 2018. On that date, users who still had iDEN phones had to replace them with standard phones with GSM/3G/4G network support, and the number with one in 9-digit format. Despite this fact, mobile phones registered outside the 11–19 (

Most citizens only know the ''190'' (Military Police) number for emergencies, but ''192'' (ambulance), ''193'' (firefighters) and ''199'' (civil defense) are also commonly known. Usually a call to 190 (military police) describing an emergency with a non-criminal nature will be redirected to the proper number or provide assistance if they are qualified to (as in cases of choking children).

in Rio de Janeiro, so the redirecting numbers were initially reachable only from the 12 World Cup host cities, but later the change was extended to the entire country. Some states and municipalities may have additional short ''1nn'' public utility numbers for other services. For example, in many cities, such as São Paulo, one can get information, make requests and complaints about most services and issues with the municipal administration by dialing ''156''. Regional utilities for services such as electricity and water supply may also have short access numbers starting with ''1''. In contrast to emergency numbers, which are always toll-free, calls to such services may or may not be charged. Landline telephone companies' customer service numbers have been normalized as ''103'', followed by a two-digit code. For example,

customers contact the company's customer service dialing ''103–21''. For most mobile carriers, the number is ''105'', followed by a one-digit code (e.g., ''105-2'' for Claro). For cable and satellite television operators, the number is ''106'', followed by a two-digit code (e.g., ''106-21'' for Net and ''106-11'' for SKY Brasil).


Long-distance dialing

The Brazilian system for long-distance dialing is relatively unusual and somewhat confusing, insofar as the choice of long-distance carrier determines the actual digit sequence to be dialed. The standard format for writing down – but not for calling since 1999 – a long-distance phone number in Brazil is ''(aa) nnnn-nnnn'', where ''aa'' is the area code and ''nnnn-nnnn'' is the local phone number. Due to persistence of old habits from the time when carrier codes were not used (see below), the format ''(0aa) nnnn-nnnn'' is still commonly seen, but this usage is discouraged, since it may confuse customers when actually calling, despite the mobile carriers give the option to complete the call with the old dialing ''(0aa) nnnn-nnnn'' with their own code in the configuration of the

for a full list. For billing purposes, calls from mobile telephones are considered local when destined to a number belonging to the area where the cell phone is operating, while in the case of fixed telephones, such area is divided into a series of subdivisions into local areas, where only calls destined to the same city or metropolitan area are billed as local. For other calls from landlines and mobiles, it is necessary to use the provider selection code, known as CSP, a two-digit number where none of the digits can be zero and is generally limited to one number per provider. In such cases, it is usually necessary to dial a 0 followed by the CSP and area code before the phone number. The need for carrier code placement began in 1999 for landlines and around 2004 for older TDMA/CDMA networks. In GSM networks, the use of the CSP was mandatory from the beginning and in the old iDEN networks and in some VOIP networks, the CSP is not used. iDEN is discontinued, but in exceptional cases of VOIP networks that do not work with the CSP, dialing in the old mode (0 followed by the area code before the phone number) or in the international mode (+55 followed by the area code before the telephone number) is the applicable mode.


Carrier selection

To dial a long-distance number within Brazil, one needs to use a carrier selection code, to choose which long-distance carrier will be used. The carrier selection code is specified before the area code; so, to actually place a call, one 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 written down as ''(0xxaa) nnnn-nnnn'', with two actual letters ''x'' as placeholders, which the caller will replace by a carrier code. For example, to call the number ''2345-6789'' in

s are automated. The phone number to be called is prefixed with a special code. Then, as the person being called answers the telephone, they listen to a short standard recording informing them that it is a collect call. Next, the call is established and the caller is supposed to say their name and location within the next six seconds. If the person being called hangs up within those six initial seconds, nothing is charged. Otherwise, the remaining time of the call is charged to the recipient's phone line. This used to cause problems with answering machines and faxes, but the switch to digital voice mailboxes operated by the telephone companies largely eliminated that problem.

Non-geographic numbers

Non-geographic numbers usually have a three-digit prefix and a 7-digit number, preceded by the number 0 used for long distance calls. The second digit of non-geographic number prefixes is the number 0. Some 0800 numbers are 6-digit only, being that such lines generally have high user traffic. Because of this fact, despite having activated a new 7-digit number, it still keeps the 6-digit number initially assigned active. For example, Ministry of Education has 0800-61-6161/0800-061-6161. The currently allocated prefixes are: * ''0300'':

s at rates much higher than those charged on national calls. After problems due to charges considered abusive by consumers in the 90s and early 2000s, the service is rarely used today. It is also noted that the prefixes ''020'', ''060'' and ''070'' are reserved for future national-wide mobile phone numbers.


''"3/400n-nnnn"'' numbers

A special case of non-geographic numbers are eight-digit numbers in the form ''3/400n-nnnn''. They are dialed as local numbers, without any trunk, carrier or area codes, and calls to them are always charged as local, regardless of where the answering

physically is. In spite of this, there are some 300x/400x prefixes that direct calls as locations only in a specific geographic area within the area of operation of the company operating the service, or may even be used as typical local numbers. Such numbers differ from ''0300'' numbers in that the latter in the past were not charged as local calls and had their own rates (not always really flat and sometimes more like premium-rate numbers), which by law must be informed when advertising the number. ''0300'' numbers are often used, for example, by low-cost airlines' reservation systems, whereas ''400n-nnnn'' numbers are used by large but cost-conscious companies that do not wish to bear the full cost of a nationwide toll-free system, yet still do not want their customers to be put away by having to pay long-distance rates, and the "national" number system in these cases is based on the same number being contracted in all DDD areas of the country or eventually only in the areas where the company has the focus of its activity.. ''3/400n-nnnn'' numbers are also often used by

s (ISPs) for standard dial-up access. As of January 2009, ''3/400n-nnnn'' numbers are not yet available for access from all area codes or localities due to the division of the cities in the DDD areas into local subareas generally limited to the municipality or the conurbated metropolitan area, requiring the typing of ''0-xx-aa'' to call the number from landlines in the municipalities outside the local subarea to which the number special is associated. As a result, these numbers are associated with state capitals and their metropolitan regions or the largest city in the area. The company (especially in the case of ISPs) may also specify localities where the service will or will not be available, providing an alternative long-distance or toll-free number for such cases. For example, the country's largest bank, Banco do Brasil, offers the number ''4004-0001'' for its clients to access its home banking services in major cities (where most clients are) paying local rates, and the toll-free number ''0800-729-0001'' for clients elsewhere in the country.

International calls


Outbound

Outbound international calls use a ''00'' trunk prefix, followed by the carrier selection code (same as in domestic long-distance calls) and the international telephone number. So, to call the international telephone number ''cc-aa-nnnn-nnnn'' (where ''cc'' is the country code and ''aa'' the area code), one would dial ''00-xx-cc-aa-nnnn-nnnn'', where ''xx'' is the carrier selection code. Since international telephone numbers can have up to 15 digits, the maximum number of digits to be dialed is 19. For example, to call the U.S. number ''202-555-0123'' in Washington, D.C. (area code ''202''), United States (country code ''1''), using TIM as the chosen carrier (selection code ''41''), one would dial 00 41 1 202 555 0123. There is a special exception for foreign visitors who are using international roaming in Brazil. They can use the standard dialing format to call abroad from Brazil (+cc-aa-nnnn-nnnn). As of August 2016,

Inbound

Inbound international calls use ''+55 aa nnnn nnnn'' as the international telephone number, where ''aa'' is the two-digit Brazilian area code and ''nnnn nnnn'' is the 8-digit local number (9 digits for mobile numbers). This must be preceded by an

specific to the country where the call is being placed from (e.g., ''011'' from the U.S. and Canada, ''00'' from most other countries, or the actual "+" sign from many mobile networks). If the number in Brazil was supplied with an initial 0 and/or carrier selection codes, those must be omitted. For example, to call the number ''3210-9876'' in

(area code ''11'') from the United States, one would dial 011 55 11 3210 9876.


Number portability

In September 2008, ANATEL started the use of number portability in Brazilian territory, but the existing rules of the numbering plan were kept. Fixed-line customers can keep their numbers when moving their address and/or when switching telephone companies within the same municipality, and mobile lines customers can keep their numbers provided they stay within the same local area (i.e., the portion of the area code where calls are charged as local).
