📍 Geographic Location of Rio Grande do Norte
Geographic Overview
The area code 84 is the National Destination Code (NDC) assigned to the state of Rio Grande do Norte (RN) in Brazil. This geographic code covers the entire state, including its capital, Natal, and other major municipalities such as Mossoró, Parnamirim, São Gonçalo do Amarante, and Caicó. As a geographic code, it is tied to a specific region and is used for fixed-line (PSTN) and some VoIP services that are registered to addresses within the state.
Dialing Formats
For local calls within the same area code (e.g., from Natal to Natal), dial only the 8-digit subscriber number. Example: 3221-1234.
For national long-distance calls from other Brazilian area codes (e.g., from São Paulo, code 11), dial: 0 + operator code (e.g., 15) + 84 + subscriber number. Example: 0 15 84 3221-1234.
For international calls to Rio Grande do Norte from abroad, dial the international access prefix (e.g., 011 from the US), followed by Brazil's country code 55, then area code 84 and the 8-digit subscriber number. Example: +55 84 3221-1234.
Regulatory and Technical Notes
Brazil's numbering plan follows ITU-T E.164 recommendations. The area code 84 is part of the national numbering plan administered by ANATEL (Agência Nacional de Telecomunicações). Subscriber numbers in this code are 8 digits long, and the total length of a national significant number (NSN) is 10 digits (excluding the trunk prefix 0).
It is important to note that while 84 is primarily a fixed-line code, number portability allows users to retain their numbers when changing service providers, including moving from a fixed line to a mobile service, though the geographic association remains. Callers should always verify the current operator and any applicable tariffs.
Practical Guidance for Callers
- Local callers within Rio Grande do Norte can dial the subscriber number directly without the area code.
- National callers from other states must include the area code 84 after the operator selection code.
- International callers must use the +55 84 format, omitting the leading zero of the trunk prefix.
When dialing from mobile phones in Brazil, it is common to use the operator code 0 + 15 (for Vivo) or other codes, but the structure remains the same. Always ensure you have the correct 8-digit subscriber number to complete the call successfully.
