📍 Geographic Location of Minas Gerais
Geographic Coverage and Administrative Jurisdiction
The Brazilian area code 3136 is a geographic National Destination Code (NDC) allocated within the state of Minas Gerais. Specifically, prefix 3136 serves the metropolitan region of Belo Horizonte, the state capital, and its surrounding municipalities. This includes neighborhoods in the capital itself, as well as cities in the immediate metropolitan area such as Contagem, Betim, Nova Lima, and Sabará. The code is administered by the National Telecommunications Agency (ANATEL) and is assigned to fixed-line (PSTN) services, although some VoIP providers may also use it for geographic numbers.
Dialing Formats and Caller Instructions
For local calls within the 3136 area, callers must dial the 8-digit subscriber number preceded by the area code, resulting in the format 3136-XXXX. For national long-distance calls from other Brazilian states, the full format is 0 + carrier code + 31 + 36 + subscriber number (e.g., 0XX31 3136-XXXX). International callers should dial +55 31 3136-XXXX (or 0055 31 3136-XXXX from many countries). Note that the leading '0' is used for domestic trunk calls and is not part of the international dialing sequence.
Overlay and Numbering Considerations
Currently, the 31 area code does not have an overlay, meaning that 3136 is a unique prefix within the 31 NDC. However, as demand grows, ANATEL may introduce new prefixes or overlays. For callers, it is essential to always include the area code (31) when dialing from mobile phones, even for local calls, as mobile numbers require the full national number. Fixed-line numbers in the 3136 range are typically 8 digits long, and the prefix 3136 is part of the subscriber number, not a separate exchange code.
Practical Examples and Usage
To illustrate, a local Belo Horizonte number might be 3136-1234. A caller from São Paulo would dial 0XX31 3136-1234, where XX is the carrier code. An international caller from the United States would dial 011 55 31 3136-1234. This prefix is used by residential and business fixed lines, and it is important to note that calls to 3136 numbers are charged according to the caller's plan and the distance, as per Brazilian regulations.
