Area Code 3716 – Comandante Fontana, Formosa

Overview of Area Code 3716

Area code 3716 is a geographic National Destination Code (NDC) assigned to the town of Comandante Fontana and its surrounding areas in the province of Formosa, Argentina. This code is part of the national numbering plan administered by the Ente Nacional de Comunicaciones (ENACOM), following ITU-T E.164 recommendations. The region is located in the northeastern part of the country, near the Paraguay border, and is characterized by its agricultural and livestock activities.

Geographic Coverage and Administrative Jurisdiction

The 3716 area code covers the locality of Comandante Fontana, which serves as the administrative center for the Patiño Department. It also includes smaller rural settlements and estancias within the department. The nearest major urban center is the provincial capital, Formosa, which uses a different area code (370). The region is part of the Argentine Mesopotamia, a subtropical area with distinct seasonal weather patterns.

Dialing Formats and Procedures

For callers within Argentina, the national trunk prefix 0 is used before the area code when dialing from a different NDC. The subscriber number in Comandante Fontana typically consists of 6 to 7 digits, depending on the specific telephone exchange. The complete national format is:

• National (from within Argentina): 0 3716 XXX XXX
• International (from outside Argentina): +54 3716 XXX XXX

For example, a local number might be dialed as 0 3716 456789 from Buenos Aires, while an international caller would dial +54 3716 456789. When dialing within the same area code, the national trunk prefix and area code are often omitted, and only the subscriber number is used.

Overlay and Numbering Considerations

Currently, there is no overlay code for 3716; the area code is exclusive to this geographic region. However, as with many parts of Argentina, number portability allows subscribers to retain their numbers when switching between fixed-line operators, provided they remain within the same geographic area. This means that the prefix does not necessarily indicate the physical location of the line for ported numbers, but it still reflects the original geographic allocation.

Caller Instructions

Local callers within the 3716 area should dial only the subscriber number (without the area code) for local calls. National callers from other Argentine cities must include the trunk prefix 0 and the area code. International callers should use the country code +54, followed by the area code (without the leading 0) and the subscriber number. It is important to note that the leading 0 is only used for domestic calls and must be dropped when dialing from abroad.

For businesses or individuals in Comandante Fontana, ensuring that their number is correctly listed with the 3716 code is essential for seamless connectivity with the rest of Argentina and the world.
