Area Code 3843 – Quimilí, Santiago del Estero

Overview of Area Code 3843

Area code 3843 is a geographic National Destination Code (NDC) assigned to the town of Quimilí and its surrounding localities in the province of Santiago del Estero, Argentina. This code falls within the national numbering plan administered by the Ente Nacional de Comunicaciones (ENACOM), following ITU-T E.164 recommendations. Geographically, it serves the eastern part of Santiago del Estero, near the border with the Chaco province. The region is characterized by its agricultural economy and is part of the Argentine Chaco region.

Geographic Coverage and Localities

Beyond Quimilí, the code covers several smaller towns and rural areas, including but not limited to Urutaú, La Verdad, and El Caburé. These communities rely on the public switched telephone network (PSTN) and increasingly on VoIP services, but the area code remains tied to the physical location of the line.

Dialing Formats

Understanding the correct dialing procedure is essential for both local and international callers.

• National dialing (within Argentina): To call a number in Quimilí from another Argentine city, dial 0-3843-XXXXXX. The leading 0 is the national trunk prefix, 3843 is the area code, and the subscriber number is six digits long.
• International dialing (from outside Argentina): Callers should dial the international access prefix (e.g., 00 or +), followed by Argentina's country code 54, then the area code without the leading 0, and the subscriber number: +54-3843-XXXXXX.
• Local calls: Within the same area code, callers can often dial just the six-digit subscriber number, but this depends on the operator's local dialing rules. It is always safe to use the full national format.

Numbering and Overlays

As of the latest ENACOM updates, there are no overlay codes in this region. The subscriber numbers are six digits long, and the total length of a national significant number (NSN) is ten digits (including the area code but excluding the trunk prefix). No mobile numbers are assigned under this geographic code; mobile services in Argentina use distinct non-geographic codes starting with 11, 22, 33, etc.

Caller Instructions

For local callers within Quimilí, simply dial the six-digit number for local calls. For callers from other Argentine provinces, always include the trunk prefix 0 and the area code. For international callers, replace the trunk prefix with the +54 country code. Always verify the number with the recipient, as number portability may allow fixed-line numbers to be moved to other providers, but the geographic area code generally remains associated with the original location.
