Area Code 780 – Alberdi

Overview of Paraguay Area Code 780

Area code 780 is a geographic National Destination Code (NDC) assigned to the city of Alberdi, located in the Ñeembucú Department of southwestern Paraguay. This code is part of the national numbering plan administered by the Comisión Nacional de Telecomunicaciones (CONATEL) under the framework of ITU-T E.164. Alberdi is a river port city on the Paraguay River, near the Argentine border, and serves as a commercial and administrative hub for the surrounding agricultural region.

Geographic Coverage and Administration

The 780 code covers the urban area of Alberdi and its immediate rural surroundings, including districts such as Villa Franca and parts of the Ñeembucú countryside. Administratively, Alberdi is the capital of Ñeembucú Department, and the code is used for fixed-line services provided by the state-owned operator Compañía Paraguaya de Comunicaciones (COPACO) and licensed private operators. As a geographic code, it is tied to the physical location of the subscriber's line, and calls are routed over the PSTN.

Dialing Formats and Instructions

To call a fixed-line number in Alberdi from within Paraguay, subscribers must dial the national trunk prefix 0, followed by the area code 780 and the subscriber number, which typically consists of 5 digits. The complete national significant number (NSN) length is 8 digits (excluding the trunk prefix). For example, a local number might be formatted as:

• National dialing (from within Paraguay): 0 780 XXX XX
• International dialing (from abroad): +595 780 XXX XX

For instance, if the subscriber number is 45678, a caller from Asunción would dial 0 780 45678, while a caller from the United States would dial +595 780 45678. Note that when dialing from a mobile phone within Paraguay, the trunk prefix 0 is often omitted, and the number is dialed as 780 45678.

Caller Instructions

Local callers within the 780 area (i.e., calling another number with the same area code) may be able to dial only the 5-digit subscriber number, depending on the operator's local dialing plan. However, to avoid confusion, it is recommended to always use the full national format. Foreign callers must replace the trunk prefix with the country code +595 and omit any leading zero. Ensure that you have international dialing capability on your phone plan.

Overlay and Numbering Considerations

As of the current numbering plan, there is no overlay code for Alberdi; the 780 code is exclusive to this geographic area. However, number portability is not yet fully implemented for fixed lines in Paraguay, so the code generally indicates the physical location of the line. For VoIP or mobile services, users may have non-geographic numbers, but 780 remains a geographic indicator.

For businesses in Alberdi, having a local geographic number enhances trust and local presence. When marketing to international clients, always display the number in international format (+595 780 ...) to ensure correct dialing from abroad.
