Area Code 678 – Santa Rosa Del Monday

Overview of Area Code 678 (Paraguay)

Area code 678 is a geographic National Destination Code (NDC) assigned to the city of Santa Rosa del Monday and its surrounding areas within the Alto Paraná Department of Paraguay. This code is part of Paraguay's national numbering plan, which adheres to the ITU-T E.164 international standard. The country's international dialing code is +595, and when dialing from abroad, callers must use the full international format: +595 678 XXX XXX (where X represents the subscriber's local number).

Geographic Coverage and Administration

Santa Rosa del Monday is a district located in the eastern region of Paraguay, near the Paraná River and the border with Brazil. The area code 678 serves the urban center of Santa Rosa del Monday and the rural communities within its administrative jurisdiction. The district is known for its agricultural production and is part of the larger Ciudad del Este metropolitan influence. Local calls within the same area code are dialed using the seven-digit subscriber number without the area code. For calls to other regions within Paraguay, callers must dial the national trunk prefix 0, followed by the area code and the subscriber number: 0 678 XXX XXX.

Dialing Instructions

• Local calls (within Santa Rosa del Monday): Dial the 7-digit subscriber number directly (e.g., 123 4567).
• National long-distance calls (from other Paraguayan cities): Dial 0 678 followed by the subscriber number (e.g., 0 678 123 4567).
• International calls from abroad: Dial the international access prefix (e.g., 00 from most countries), then Paraguay's country code 595, then the area code 678 without the leading '0', and finally the subscriber number (e.g., +595 678 123 4567).

This area code is exclusively for fixed-line (PSTN) services. Mobile numbers in Paraguay are non-geographic and begin with the digit '9' (e.g., +595 9XX XXX XXX). No overlay codes are currently planned for 678, so the seven-digit numbering capacity is sufficient for the region's demand.

Regulatory and Technical Notes

The National Communications Commission (CONATEL) of Paraguay manages the allocation of area codes. As a geographic code, 678 is tied to the physical location of the subscriber's line. This means that calls to 678 are routed via the public switched telephone network (PSTN) to the corresponding local exchange. For businesses or residents considering VoIP services, it is important to note that number portability may allow retaining a 678 number even if moving within Paraguay, but the geographic association remains for emergency services and billing purposes. When calling from abroad, ensure you omit the leading '0' of the area code and use the +595 international prefix for proper routing.
