Area Code 3777 – Goya, Corrientes

Overview of Area Code 3777

Area code 3777 is a geographic National Destination Code (NDC) assigned to the city of Goya and its surrounding areas in the province of Corrientes, Argentina. This code is part of the national numbering plan under the country calling code +54, following the ITU-T E.164 recommendation. Goya is a significant agricultural and commercial hub in the region, located on the eastern bank of the Paraná River.

Geographic Coverage and Administration

The 3777 area code covers the administrative jurisdiction of the Goya Department, which includes the city of Goya itself and several smaller towns and rural localities. Key populated centers within this area include Carolina, San Isidro, and Colonia Carolina. The region is part of the Corrientes Province, which borders Paraguay to the north and is known for its wetlands and agricultural production.

Dialing Formats

When calling a landline in Goya from within Argentina, you must dial the national trunk prefix 0, followed by the area code 3777 and the subscriber number. The subscriber number for this area is typically 7 digits long. The complete national dialing format is:

• 0-3777-XXX-XXXX (from within Argentina)

For international callers, the format requires the Argentine country code +54, followed by the area code (without the leading 0) and the subscriber number:

• +54-3777-XXX-XXXX (from outside Argentina)

For example, to call a local number 456-7890 in Goya, a caller from Buenos Aires would dial 0-3777-456-7890, while an international caller from the United States would dial +54-3777-456-7890.

Overlay and Numbering Considerations

As of the latest updates, there is no overlay plan in effect for the 3777 area code, meaning that local calls within the same area code do not require the area code to be dialed. However, for calls from other area codes within Argentina, the full national format (0-3777-XXX-XXXX) is mandatory. Mobile numbers in Argentina are non-geographic and use the prefix 15 after the area code when dialing from a landline, but this does not affect the fixed-line numbering of Goya.

Caller Instructions

For local callers within Goya, simply dial the 7-digit subscriber number. For long-distance callers within Argentina, always include the trunk prefix 0 and the area code. International callers must replace the trunk prefix with the +54 country code and omit the leading 0. Ensure you check the correct time zone (Argentina Time, UTC-3) to avoid calling at inconvenient hours.

This area code is essential for businesses, government offices, and residents in Goya, providing reliable PSTN and VoIP connectivity across the region.
