📍 Geographic Location of Amazonas
Geographic Coverage and Administrative Jurisdiction
Area code 97 is a geographic National Destination Code (NDC) assigned to the state of Amazonas in Brazil. It serves the central-southern portion of the state, including the capital Manaus and its metropolitan region, as well as several interior municipalities. The code covers a vast area of the Amazon rainforest, with cities such as Manacapuru, Iranduba, and Presidente Figueiredo falling within its boundaries. Administratively, the code is managed by the Agência Nacional de Telecomunicações (ANATEL) and is allocated to fixed-line (PSTN) services, though some VoIP and mobile services may also use it for local routing.
Dialing Formats and Caller Instructions
For local calls within the same area code, Brazilian users typically dial only the eight-digit subscriber number (e.g., 3232-1000). For long-distance calls from other Brazilian states, the format is: 0 + carrier code (XX) + 97 + subscriber number. For example, to call a fixed line in Manaus from São Paulo, you would dial 0XX97 3232-1000. International callers must use the country code +55, followed by the area code and subscriber number, omitting the leading zero of the trunk prefix. Thus, a call from the United States to Manaus would be dialed as +55 97 3232-1000.
Overlay and Numbering Considerations
As of 2024, area code 97 does not have an overlay code; it operates as a standalone geographic code. However, due to increasing demand, ANATEL has implemented number pooling and conservation measures. Subscriber numbers are eight digits long, and the first digit of the subscriber number may indicate the service type (e.g., fixed vs. mobile). For mobile numbers within the 97 code, the format is 9XXXX-XXXX, and they are non-geographic in nature, but they are still associated with the 97 NDC for routing purposes.
Practical Guidance for Callers
When calling from abroad, always replace the local trunk prefix (0) with the international access code of your country, then dial +55, followed by 97 and the local number. For example, a caller in the UK would dial 00 55 97 3232-1000. If you are within Brazil but outside Amazonas, you must select a long-distance carrier by dialing its two-digit code after the trunk prefix (0). For instance, using Embratel (21), you would dial 021 97 3232-1000. Always verify the number length: fixed lines have eight digits, while mobile numbers have nine digits starting with 9. This distinction is crucial for successful call completion.
