Area Code 345 – Corpus Christi

Overview of Area Code 345 (Corpus Christi, Paraguay)

Area code 345 is a geographic National Destination Code (NDC) assigned to the town of Corpus Christi and its surrounding administrative district, located in the Canindeyú Department of eastern Paraguay. This code is part of the national numbering plan administered by the Comisión Nacional de Telecomunicaciones (CONATEL), following the ITU-T E.164 recommendation. The region is characterized by its agricultural economy and proximity to the Paraná River, which borders Brazil.

Geographic Coverage and Jurisdiction

The 345 area code serves the urban area of Corpus Christi and the rural communities within its district. Corpus Christi is situated approximately 350 kilometers east of Asunción, the capital, and is accessible via Route 10. The code is used exclusively for fixed-line (PSTN) services, including traditional copper lines and, increasingly, fixed wireless and VoIP-based local loops. No overlay code has been assigned to this region; therefore, 345 remains the sole geographic code for the area.

Dialing Formats and Procedures

For callers within Paraguay, dialing a Corpus Christi number requires the national trunk prefix 0, followed by the area code and the subscriber number. The national significant number (NSN) for this region is eight digits long, comprising the two-digit area code and a six-digit local number. The complete national dialing format is:

• National (domestic) call: 0 345 XXX XXX
• International call from abroad: +595 345 XXX XXX

When calling from a mobile phone within Paraguay, the same national format applies. For international callers, the plus sign (+) represents the international access prefix (00 in most countries), followed by Paraguay's country code 595, then the area code 345 without the leading trunk prefix. For example, to call a fixed line in Corpus Christi from the United States, one would dial 011 595 345 XXX XXX.

Local vs. International Caller Instructions

Local callers within the 345 area can often dial the six-digit subscriber number directly without the area code, depending on their service provider's configuration. However, for clarity and reliability, it is recommended to always use the full national format. Foreign callers must ensure they replace the international access code with the + sign when using a mobile device, and they should never drop the area code even when calling from a nearby region.

Service Considerations

Fixed-line numbers under 345 are not portable to mobile networks, and mobile numbers in Paraguay use distinct prefixes (e.g., 961, 981, 991) that are non-geographic. As a result, the 345 code is strictly associated with fixed locations. Businesses in Corpus Christi often use these lines for customer service and administrative purposes, and the code is recognized as a reliable indicator of a local presence.
