📍 Geographic Location of Posadas, Misiones
Overview of Area Code 376
Area code 376 is a geographic National Destination Code (NDC) assigned to the city of Posadas, the capital of the Misiones Province in northeastern Argentina. It serves the metropolitan area of Posadas and several surrounding localities within the department of Capital and nearby areas. As part of the Argentine national numbering plan, this code is used for fixed-line (PSTN) services, including traditional copper lines and fiber-optic or cable-based VoIP services that are provisioned as fixed lines.
Geographic Coverage and Administration
Posadas is the largest city in Misiones and serves as the administrative, commercial, and cultural hub of the province. The city is located on the eastern bank of the Paraná River, directly across from Encarnación, Paraguay. The area code 376 covers not only the urban center of Posadas but also the surrounding towns and rural areas that are part of the local exchange area. These include localities such as Garupá, Candelaria, Santa Ana, and San Ignacio (the latter being famous for its Jesuit ruins). The region is part of the Argentine Mesopotamia, and its economy is driven by services, commerce, and tourism, with connections to the Yacyretá hydroelectric dam and the international bridge to Paraguay.
Dialing Formats
When calling a fixed-line number in Posadas from within Argentina, the subscriber number is seven digits long, and the full national significant number (NSN) consists of the area code plus the subscriber number: 376 + 7 digits. The national trunk prefix is 0, so a domestic call from another province must be dialed as 0-376-XXX-XXXX. For example, to call a Posadas number from Buenos Aires, you would dial 0 376 456 7890.
From outside Argentina, callers must use the international prefix (typically 00 or +) followed by the country code 54, the area code 376 (without the leading 0), and the seven-digit subscriber number. Thus, an international call to the same number would be dialed as +54 376 456 7890. Note that the national trunk prefix (0) is not used when dialing from abroad.
Overlay and Numbering Considerations
As of the latest ITU-T E.164 data, area code 376 does not have an overlay code. The region is served solely by this NDC. However, due to the growth of mobile services, some numbers with the 376 prefix may be assigned to mobile operators, but this is not the norm. Mobile numbers in Argentina are identified by the leading digit 9 after the country code (e.g., +54 9 376 XXX-XXXX), but this is not part of the fixed-line area code. For fixed-line numbers, the subscriber number is always seven digits, and the area code is always 376.
Caller Instructions
For local callers within the Posadas area: if you are dialing a number within the same area code, you can typically omit the area code and dial just the seven-digit subscriber number. However, for clarity and to avoid misdials, it is recommended to use the full national format. For long-distance callers within Argentina, always include the trunk prefix 0 and the area code. For international callers, use the plus sign (+) followed by 54 and 376, then the subscriber number. Always ensure you have the correct seven-digit subscriber number, as numbers are not portable across geographic areas in Argentina.
