Area Code 3774 – Curuzú Cuatiá, Corrientes

Overview of Area Code 3774

Area code 3774 is a geographic National Destination Code (NDC) assigned to the city of Curuzú Cuatiá and its surrounding localities in the province of Corrientes, Argentina. This code falls under the national numbering plan administered by the Ente Nacional de Comunicaciones (ENACOM), following ITU-T E.164 recommendations. Curuzú Cuatiá is a key agricultural and commercial hub in the eastern part of Corrientes, near the border with Entre Ríos province.

Geographic Coverage and Jurisdiction

The 3774 code covers the urban area of Curuzú Cuatiá and several nearby rural districts, including the towns of Colonia Libertad, Colonia San Ramón, and Estación Torrent. The region is part of the Departamento Curuzú Cuatiá, which is administratively dependent on the provincial government of Corrientes. The code is used for fixed-line services (PSTN) and is also utilized by some VoIP providers for geographic numbering.

Dialing Formats

For local calls within the same area code, subscribers typically dial the 7-digit subscriber number directly (without the area code). For example, to call a local number 456-7890 from another line in Curuzú Cuatiá, simply dial 456-7890.

For national long-distance calls from other Argentine cities, the format is: 0 (trunk prefix) + 3774 (area code) + 456-7890 (subscriber number). Thus, a call from Buenos Aires would be dialed as 0 3774 456-7890.

For international calls originating from outside Argentina, callers must use their country's international access code (e.g., 00 in many European countries, 011 from the US/Canada), followed by Argentina's country code 54, then the area code without the leading zero, and the subscriber number. The complete international format is: +54 3774 456-7890.

Overlay and Numbering Considerations

As of the latest ENACOM updates, there is no overlay code for 3774; the area code remains exclusive to the Curuzú Cuatiá region. However, due to the growth of VoIP and mobile services, some users may have non-geographic numbers that appear similar, but they are not part of the geographic numbering plan. Always verify the presence of the area code when dialing from a mobile phone, as Argentine mobile numbers are 10 digits long (without the leading 0) and start with 15 after the area code for calls to landlines from mobiles.

Caller Instructions

• Local callers (within 3774): dial the 7-digit number.
• National callers (outside 3774): dial 0 3774 followed by the 7-digit number.
• International callers: dial +54 3774 followed by the 7-digit number (omit the leading 0).

When calling from a mobile phone to a landline in Curuzú Cuatiá, Argentine mobile users must dial 0 3774 followed by the number, even if they are in the same area code, because mobile-to-landline calls require the national trunk prefix.
