Overview of Area Code 3781
Area code 3781 is a geographic National Destination Code (NDC) within the Argentine national numbering plan, assigned to the town of Caá Catí and its surrounding rural districts in the province of Corrientes. Located in the northeastern region of Argentina, near the Iberá Wetlands, Caá Catí is a small administrative and agricultural center. The code covers the urban area of Caá Catí and several nearby localities, including Lomas de Vallejos and Colonia Santa Rosa, which rely on the same local exchange infrastructure.
Dialing Formats
When calling a fixed-line number in Caá Catí from within Argentina, subscribers must dial the national trunk prefix 0, followed by the area code 3781 and the local subscriber number. Local numbers in this area consist of 6 digits, making the complete national format 0-3781-XXXXXX. For example, a local number might be dialed as 0 3781 456789 from other Argentine provinces.
For international callers, the Argentine country code +54 replaces the trunk prefix. The international dialing format becomes +54 3781 XXXXXX, omitting the leading zero of the national trunk prefix. Thus, the same number would be dialed as +54 3781 456789 from abroad.
Within the same area code, local calls may be placed using only the 6-digit subscriber number, depending on the operator's local dialing rules. However, for clarity and to avoid misdialing, it is recommended to use the full national format even for local calls.
Regulatory and Technical Notes
Argentina's numbering plan is regulated by the Ente Nacional de Comunicaciones (ENACOM). Area code 3781 is classified as a geographic code, meaning that the tariff and routing are based on the physical location of the fixed-line subscriber. The code is part of the Corrientes province numbering area, which is subdivided into several NDCs, including 3781 for Caá Catí and 3782 for other nearby towns.
As with all Argentine fixed-line numbers, subscribers may be subject to number portability, allowing them to retain their number when switching service providers. However, the geographic nature of the code remains unchanged even after porting, as the code is tied to the original exchange area.
For callers using VoIP services or mobile networks, it is essential to include the appropriate trunk prefix (0) when dialing from within Argentina, as mobile networks require the full national number. International callers should always use the +54 country code and omit the leading zero.
