Area Code 3855 – Suncho Corral, Santiago del Estero

Overview of Area Code 3855

Area code 3855 is a geographic National Destination Code (NDC) assigned to the town of Suncho Corral and its surrounding rural districts within the province of Santiago del Estero, Argentina. This code is part of the national numbering plan administered by the Ente Nacional de Comunicaciones (ENACOM) under ITU-T E.164 recommendations. The region is characterized by its agricultural economy and its position along National Route 98, approximately 120 kilometers southeast of the provincial capital, Santiago del Estero.

Geographic Coverage and Jurisdiction

The 3855 numbering area encompasses Suncho Corral, the head town of the Juan F. Ibarra Department, as well as smaller localities such as Villa Matará, Los Acuña, and El Caburé. Administratively, these communities fall under the jurisdiction of the Santiago del Estero provincial government. The code serves both fixed-line PSTN subscribers and, in some cases, fixed wireless or VoIP services that are registered to this geographic area.

Dialing Formats and Procedures

For callers within Argentina, the national dialing format requires the use of a trunk prefix 0 followed by the area code and the subscriber number. The complete national significant number for a local line is 0-3855-XXXXXX, where the subscriber number typically consists of six digits. When calling from abroad, the international format omits the trunk prefix and uses Argentina's country code +54, resulting in +54 3855 XXXXXX. For example, a local number 456789 would be dialed as 0-3855-456789 domestically and +54 3855 456789 internationally.

Local calls within the same area code do not require the area code; subscribers can dial the six-digit number directly. However, all calls originating from outside the 3855 area—whether from other Argentine provinces or from abroad—must include the appropriate trunk prefix or country code. There are no overlay codes currently assigned to this region, so the area code remains mandatory for all non-local calls.

Caller Instructions

For local callers: To reach a neighbor in Suncho Corral, simply dial the six-digit subscriber number. For domestic long-distance callers: Dial 0 then 3855 then the subscriber number. For international callers: Dial the international access code (e.g., 00 from most countries), then 54, then 3855, then the subscriber number. Mobile and VoIP users should ensure they have the correct international prefix when calling from outside Argentina.
