Area Code 3496 – Esperanza, Santa Fe

Overview of Area Code 3496

Area code 3496 is a geographic National Destination Code (NDC) within the Argentine national numbering plan, governed by ITU-T E.164 and administered by the Ente Nacional de Comunicaciones (ENACOM). It serves the central-eastern region of Santa Fe Province, specifically the department of Las Colonias, with the city of Esperanza as its primary urban center. The code covers a mix of urban and rural localities, including but not limited to San Carlos Centro, San Carlos Norte, San Carlos Sur, Franck, Humboldt, and Progreso. These communities form an agricultural and dairy-producing corridor northwest of Santa Fe City, the provincial capital.

Geographic Coverage and Jurisdiction

The 3496 numbering area falls within the administrative jurisdiction of the Province of Santa Fe, Argentina. It is bordered by area codes 342 (Santa Fe City) to the east, 3492 (Rafaela) to the north, and 3497 (San Justo) to the south. The region is characterized by its productive pampas, with Esperanza serving as a commercial and administrative hub. The code is classified as a geographic number, meaning that the number is tied to a physical location and the tariff structure reflects local and national calling zones.

Dialing Formats and Procedures

Understanding the correct dialing sequence is essential for both domestic and international callers.

• Domestic calls within Argentina (excluding the same area code): Dial the national trunk prefix 0, followed by the area code 3496, and then the subscriber number (which typically has 6 to 7 digits). For example, to call a landline in Esperanza from Buenos Aires, you would dial: 0 3496 4XXXXXX.
• Domestic calls within the same area code (local calls): Dial only the subscriber number (without the trunk prefix or area code). For instance, calling a neighbor in Esperanza: 4XXXXXX.
• International calls from outside Argentina: Dial the international access prefix (e.g., 00 from most countries, or +), followed by Argentina's country code 54, then the area code 3496 (omitting the leading 0), and finally the subscriber number. Example from the United States: 011 54 3496 4XXXXXX or +54 3496 4XXXXXX.

Overlay and Numbering Considerations

As of the latest ENACOM data, area code 3496 does not have an overlay code; it is the sole NDC for its geographic region. However, due to the growth of mobile and VoIP services, ENACOM has implemented number portability across Argentina, allowing users to retain their numbers when changing service providers. This applies to both geographic and mobile numbers, but the geographic significance of the prefix remains for routing and tariff purposes. Callers should always verify the current dialing procedures with their service provider, as local regulations may evolve.
