Area Code 3491 – Ceres, Santa Fe

Overview of Area Code 3491

Area code 3491 is a geographic National Destination Code (NDC) within the Argentine numbering plan, assigned to the city of Ceres and its surrounding localities in the northwestern part of Santa Fe Province. Ceres is a key agricultural and railway hub near the provincial border with Santiago del Estero, and this code also serves nearby towns such as Suardi, Villa Trinidad, and San Guillermo. The region is part of the Argentine PSTN and is also used by VoIP and mobile services that are allocated geographic numbers.

Dialing Formats

When calling a fixed-line number in Ceres from within Argentina, the subscriber number has 7 digits and must be preceded by the area code. The national trunk prefix is 0, so the complete national format is:

• 0 3491 XXX XXXX (national dialing)

For international callers, the Argentine country code is +54, and the trunk prefix is omitted. The international format is:

• +54 3491 XXX XXXX

For example, a local number 456-7890 would be dialed as 03491 456-7890 from within Argentina and as +54 3491 456-7890 from abroad.

Geographic Coverage and Administration

Ceres is the administrative center of the San Cristóbal Department in Santa Fe. The area code covers a rural and semi-urban zone characterized by agricultural production, including soybean and wheat farming. The region is served by fixed-line operator Telecom Argentina, which provides PSTN and fiber-optic broadband services. As with all Argentine geographic codes, the number range is managed by the Ente Nacional de Comunicaciones (ENACOM), the national regulatory body.

Caller Instructions

For local callers within the same area code, dialing the 7-digit subscriber number directly is possible in most cases. However, due to number portability and the expansion of mobile services, it is recommended to always include the area code when dialing from a mobile phone. For foreign callers, ensure you have the correct country code (+54) and omit the leading zero of the trunk prefix. Calls to this geographic number are typically charged at standard national rates, depending on the caller's carrier and plan.

Overlay and Numbering Considerations

Currently, there is no overlay code for 3491, meaning the area code serves a distinct geographic region without sharing with another NDC. However, as Argentina transitions to a fully integrated numbering plan, users may encounter numbers that appear with different formats, especially when using VoIP services. Always verify the complete number with the recipient to avoid misdialing.
