Area Code 451 – Colonia Volendam

Overview of Area Code 451 (Colonia Volendam, Paraguay)

Area code 451 is a geographic National Destination Code (NDC) assigned to the locality of Colonia Volendam, a Mennonite settlement located in the San Pedro Department 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 region is primarily agricultural, known for its dairy and beef production, and is served by fixed-line PSTN infrastructure, though VoIP services are increasingly available.

Geographic Coverage and Administrative Jurisdiction

Colonia Volendam is situated in the District of Santa Rosa del Aguaray, within the San Pedro Department. The area code covers the town itself and the surrounding rural communities. The administrative jurisdiction falls under the Municipalidad de Santa Rosa del Aguaray, which coordinates local services, including telecommunications. The region is part of Paraguay's interior, located approximately 400 kilometers northeast of the capital, Asunción.

Dialing Formats and Caller Instructions

Local Calls (Within Paraguay)

To call a fixed-line number in Colonia Volendam from another location in Paraguay, dial the national trunk prefix 0, followed by the area code 451, and the subscriber number (typically 6 to 7 digits). For example, to reach a local number 123456, you would dial:

• From Asunción or other departments: 0 451 123456
• From within the same area code (local call): 451 123456 (if 7-digit dialing is used) or simply the subscriber number, depending on the local exchange configuration.

International Calls (From Outside Paraguay)

To call Colonia Volendam from abroad, dial the international access prefix (e.g., 00 or +), then Paraguay's country code +595, followed by the area code 451 (without the leading '0'), and the subscriber number. For example, from the United States, you would dial:

• +595 451 123456

Note that the leading '0' of the national trunk prefix is omitted when dialing from outside Paraguay.

Overlay Considerations and Numbering Plan

As of the latest CONATEL updates, there is no overlay code for the 451 area. The numbering plan for geographic codes in Paraguay typically uses 6 to 7-digit subscriber numbers, and the total length of a national significant number (NSN) is 9 digits (including the area code). No overlay is currently planned, but users should verify with their service provider for any changes.

Important Notes for Callers

• PSTN vs. VoIP: Traditional PSTN lines are prevalent, but VoIP services may route calls differently. Ensure you have the correct access numbers.
• Emergency Services: For emergencies, dial 911 (national emergency number) or local police/fire numbers, which are not tied to the area code.
• Time Zone: Paraguay operates on Paraguay Time (PYT, UTC-4) and observes daylight saving time (PYST, UTC-3) from October to March. Consider time differences when calling.
