Overview of Area Code 671 (Mayor Otano, Paraguay)
Area code 671 is a geographic National Destination Code (NDC) assigned to the town of Mayor Otano and its surrounding districts within the Itapúa Department of Paraguay. Mayor Otano, also known as Mayor Otaño, is located in the southeastern region of the country, near the Paraná River and the border with Argentina. The code serves the urban center and rural communities that rely on the town's administrative and commercial infrastructure.
Geographic Coverage and Jurisdiction
The 671 area code is allocated under the national numbering plan administered by the Comisión Nacional de Telecomunicaciones (CONATEL). It covers the municipality of Mayor Otano, which is part of the larger Itapúa Department. The region is primarily agricultural, with connections to the departmental capital, Encarnación, via Route 6. The code is used for fixed-line (PSTN) services, including traditional copper lines and, increasingly, fixed wireless and VoIP-based local access.
Dialing Formats and Caller Instructions
For local callers within Paraguay, dialing a number in the 671 area code requires the national trunk prefix 0 followed by the area code and the subscriber number. The subscriber number length is typically 6 digits, making the complete national number format: 0 671 XXX XXX. For example, a local call from Asunción to a fixed line in Mayor Otano would be dialed as 0 671 123 456.
International callers must use Paraguay's country code +595, followed by the area code without the leading trunk prefix, and the subscriber number. For instance, from the United States, you would dial 011 595 671 123 456; from most European countries, 00 595 671 123 456. It is essential to omit the initial '0' of the national trunk prefix when dialing from abroad.
Overlay and Numbering Considerations
As of the latest updates, there is no overlay code for the 671 area. The region uses a closed numbering plan for fixed lines, meaning the area code is mandatory for all calls, even within the same locality. Mobile numbers in Paraguay are non-geographic and use distinct prefixes (e.g., 961-999 for mobile), so calls from a mobile to a 671 landline must include the area code.
Services and Usage
The 671 code supports standard telephony services, including voice calls, fax, and dial-up internet in some areas. With the expansion of fiber-optic networks, many businesses and residences now have access to high-speed broadband, but the area code remains tied to the geographic location for routing purposes. Emergency services and directory assistance are accessed via national short codes, not through the area code.
