Area Code 3493 – Sunchales, Santa Fe

Overview of Area Code 3493

Area code 3493 is a geographic National Destination Code (NDC) within the Argentine numbering plan, assigned to the city of Sunchales and its surrounding localities in the central-western part of Santa Fe Province. This region is part of the Argentine Pampas, an area known for its agricultural and dairy production. The code covers Sunchales itself, along with nearby towns and rural areas such as Ataliva, Humberto Primo, and Villa San José, which rely on Sunchales as their primary urban center.

Geographic Coverage and Administration

Sunchales is the head of the Castellanos Department, located approximately 200 kilometers northwest of the provincial capital, Santa Fe de la Vera Cruz. The area code 3493 is administered under the national telecommunications regulator ENACOM (Ente Nacional de Comunicaciones), which oversees the allocation of numbering resources in compliance with ITU-T E.164 recommendations. The region is served by both fixed-line operators (such as Telecom Argentina and Telefónica) and mobile carriers, though the geographic code applies specifically to fixed-line services.

Dialing Formats

For local calls within the 3493 area, subscribers can dial the 7-digit subscriber number directly (e.g., 42-XXXX). For calls originating from other Argentine provinces, the format is 0-3493-42-XXXX, where the leading 0 is the national trunk prefix. For international callers, the full international format is +54 3493 42-XXXX, replacing the trunk prefix with the Argentine country code (+54). It is important to note that the area code is mandatory for all calls from outside the local calling area, even if the destination is within the same province.

Overlay and Numbering Considerations

As of the latest ENACOM updates, there is no overlay plan for 3493; the area code is unique to this geographic region. However, due to the growth of VoIP and mobile services, callers should always verify the correct prefix when dialing from a mobile phone, as mobile numbers in Argentina are 10 digits long and begin with 15 after the area code for domestic calls (e.g., 0-3493-15-XXX-XXXX for mobile numbers within the same area). This distinction is crucial for avoiding misdialed calls.

Practical Guidance for Callers

For local callers within Sunchales, simply dial the 7-digit local number. For callers from other cities in Argentina, use the national long-distance format with the trunk prefix 0. International callers should replace the trunk prefix with the +54 country code and omit the leading zero. Always ensure you have the correct subscriber number, as numbers within this code are not portable to other geographic areas, but fixed-line numbers can be ported between operators within the same area.
