Area Code 42 – San Pedro Del Ycua Mandyju

Overview of Paraguay Area Code 42

Area code 42 is a geographic National Destination Code (NDC) assigned to the San Pedro Department in Paraguay, with its primary administrative and service center in the city of San Pedro del Ycuamandyyú (often referred to as San Pedro). This code is part of the national numbering plan under the country calling code +595, following the ITU-T E.164 recommendation. The region is located in the eastern part of the country, bordered by the departments of Amambay, Canindeyú, Caaguazú, Cordillera, and Presidente Hayes.

Geographic Coverage and Dialing Formats

The 42 code covers a mix of urban and rural areas, including the departmental capital and several districts. When dialing a fixed-line number within Paraguay from another area code, you must include the trunk prefix 0 followed by the area code and the subscriber number. The national significant number (NSN) for fixed lines in this region is 9 digits long, comprising the area code (2 digits) and a 7-digit subscriber number.

• National dialing (from other Paraguayan cities): Dial 0 42 XXX XXXX.
• International dialing (from abroad): Dial +595 42 XXX XXXX (omit the leading 0).
• Local dialing within the same area code: Typically, only the 7-digit subscriber number is required, though some exchanges may still require the full national format.

For example, to call a fixed line in San Pedro del Ycuamandyyú from the United States, you would dial +595 42 123 4567 (replace with the actual subscriber number).

Administrative and Regulatory Context

The allocation and management of area codes in Paraguay are overseen by the Comisión Nacional de Telecomunicaciones (CONATEL). As a geographic code, 42 is tied to the physical location of the telephone exchange, and calls are routed over the public switched telephone network (PSTN). This means that the code is not portable across different geographic regions; if a subscriber moves outside the San Pedro Department, they would typically need to obtain a new number with the appropriate area code.

Caller Instructions

For callers within Paraguay, always use the trunk prefix 0 when dialing from a different area code or from a mobile phone. For international callers, replace the 0 with the country code +595. It is important to note that mobile numbers in Paraguay have their own non-geographic prefixes (e.g., 961, 981, 991) and are not part of the geographic numbering plan.

As the region continues to develop, telecommunications infrastructure is expanding, but some rural areas may still rely on older analog exchanges. For the most accurate and up-to-date dialing information, consult your local telecom provider or the official CONATEL guidelines.
