Area Code 73 – San Cosme

Overview of Area Code 73 (San Cosme, Paraguay)

Area code 73 is a geographic National Destination Code (NDC) assigned to the San Cosme and San Damián district, located in the department of Itapúa, in the southeastern region of Paraguay. This code is part of the national numbering plan administered by the Comisión Nacional de Telecomunicaciones (CONATEL), following ITU-T E.164 recommendations. The code 73 serves a predominantly rural and agricultural area, with the town of San Cosme as its administrative center.

Geographic Coverage and Jurisdiction

The 73 area code covers the district of San Cosme, which includes the urban center and surrounding rural communities. San Cosme is situated near the Paraná River, close to the border with Argentina. The area is known for its Jesuit missions heritage, particularly the ruins of San Cosme y San Damián, a UNESCO World Heritage Site. The district is part of the Itapúa department, whose capital is Encarnación (area code 71).

Dialing Formats and Procedures

For local callers within Paraguay, dialing a number in the San Cosme area requires the trunk prefix 0, followed by the area code 73 and the subscriber number. The subscriber number length in this area is typically 6 digits, resulting in a total national significant number (NSN) of 8 digits (excluding the trunk prefix). For example, to call a landline in San Cosme from Asunción, you would dial: 0 73 123 456.

For international callers, the dialing format is: +595 73 123 456, where +595 is the country code for Paraguay, 73 is the area code, and the subscriber number follows. It is important to note that the trunk prefix '0' is not included when dialing from abroad.

Overlay and Numbering Considerations

Currently, there is no overlay plan for area code 73; it remains the sole geographic code for the San Cosme district. However, as part of the national numbering plan, all geographic codes in Paraguay are subject to potential changes due to number exhaustion or regulatory decisions. Callers should always verify the current dialing procedures with their service provider or CONATEL if they encounter issues.

Caller Instructions

Local callers (within Paraguay): Always include the trunk prefix '0' before the area code when dialing from a different area. For calls within the same area code, local dialing may allow omitting the area code, but it is recommended to use the full national format to avoid misdialing.

International callers: Replace the trunk prefix '0' with the country code +595, and drop any leading '0' from the area code. Ensure you have the correct international exit code for your country (e.g., 011 from the US, 00 from most European countries).

Usage and Services

Area code 73 is primarily used for fixed-line PSTN services, including residential and business lines. As in many rural areas, VoIP services are increasingly available, but the geographic code remains tied to the physical location for emergency services and number portability purposes. Mobile numbers in Paraguay have their own non-geographic codes (e.g., 96x, 97x, 98x, 99x) and are not affected by this area code.
