📍 Geographic Location of Amazonas
Geographic Coverage and Administrative Jurisdiction
The country calling code +55, followed by the National Destination Code (NDC) 92, routes calls to the state of Amazonas in Brazil's North Region. This geographic area code serves the state capital Manaus and its metropolitan region, including municipalities such as Manacapuru, Iranduba, Rio Preto da Eva, and Careiro. The area code is administered under the Brazilian National Telecommunications Agency (ANATEL) numbering plan, which designates 92 as a geographic code for the state of Amazonas. It is important to note that the code covers only the central and eastern portions of the state; the western municipalities, such as Tabatinga and Tefé, use the code 97.
Dialing Formats and Caller Instructions
For local calls within the 92 area code, Brazilian subscribers dial only the eight-digit subscriber number (e.g., 3222-0000). For domestic long-distance calls from other Brazilian states, callers must dial 0 + carrier code + 92 + subscriber number. For example, from São Paulo, a call to Manaus would be dialed as 0 15 92 3222-0000, where '15' is an example of a long-distance carrier selection code. International callers should dial +55 92 followed by the eight-digit subscriber number, omitting the leading trunk prefix '0'. For instance, from the United States, one would dial 011 55 92 3222-0000. When dialing from a mobile phone in Brazil, the same long-distance rules apply, but the call may be preceded by the digit '9' for mobile numbers, as Brazilian mobile numbers have nine digits starting with '9' after the area code.
Overlay and Numbering Considerations
Currently, there is no overlay code for the 92 area code; the region uses a single NDC. However, due to the growing demand for telecommunication services in Manaus, ANATEL has implemented number pooling and conservation measures. Subscriber numbers in the 92 area code are eight digits long, and the first digit of the subscriber number can range from 2 to 9, with specific ranges allocated to fixed and mobile services. Fixed-line numbers typically start with 2 to 5, while mobile numbers start with 9. This distinction is crucial for routing and for understanding the nature of the called party. For instance, a fixed-line number in Manaus might be +55 92 2123-4567, while a mobile number would be +55 92 98123-4567.
Practical Guidance for Callers
When calling from abroad, always replace the leading '0' of the Brazilian trunk prefix with the international access code of your country, followed by Brazil's country code 55. Ensure you drop any leading '0' from the area code when dialing internationally. For example, a call from the UK to a fixed line in Manaus would be dialed as 00 55 92 3222-0000. For travelers within Brazil, it is essential to include the carrier selection code when making long-distance calls; otherwise, the call may not be completed. Always verify the correct number of digits: eight for fixed lines and nine for mobile lines (including the leading '9'). Misunderstanding these formats can lead to failed calls or misrouting.
