The region is situated in the northeastern part of Argentina, within the Gran Chaco plain, and is characterized by its agricultural and forestry activities.

Dialing Formats and Caller Instructions
For local callers within Argentina, the national dialing format for a fixed-line number in this area is: 0 3734 XXX XXX.

Overlay and Numbering Considerations
As of the latest ENACOM updates, there are no overlay codes in this area; the 3734 code is the sole NDC for the region. However, due to the growth of mobile and VoIP services, fixed-line numbers may be ported to mobile networks, but the geographic area code remains unchanged. Callers should be aware that calls to this code are billed as domestic long-distance when dialed from other Argentine provinces, and as international when dialed from outside the country.
