Area Code 3460 – Santa Teresa, Santa Fe

Overview of Area Code 3460

Area code 3460 is a geographic National Destination Code (NDC) within the Argentine telephone numbering plan, assigned under the international country code +54. It serves the locality of Santa Teresa and its surrounding areas in the southern part of Santa Fe Province. This region falls under the administrative jurisdiction of the Departamento Constitución and is part of the broader Rosario metropolitan influence.

The code covers a predominantly rural and semi-urban zone, with Santa Teresa as the primary town. Other nearby localities, such as Pavón and Peyrano, may also be reached through this code, depending on the specific telephone exchange. The area is characterized by agricultural activity and small-to-medium enterprises, with a modest population density.

Dialing Formats

For callers within Argentina, the national trunk prefix 0 is used before the area code. The complete national significant number for a local subscriber is 03460 + local number. Local numbers in this code typically consist of 6 digits, making the full national number 10 digits (excluding the trunk prefix).

• National dialing (from within Argentina): 0 3460 XXX XXX
• International dialing (from outside Argentina): +54 3460 XXX XXX

For example, if a local number is 456789, a caller in Buenos Aires would dial 03460 456789, while an international caller would dial +54 3460 456789.

Caller Instructions

Local callers within the same area code may sometimes dial only the 6-digit subscriber number, but due to the introduction of the National Numbering Plan (Resolución 418/2019), closed dialing is now mandatory across Argentina. Therefore, all domestic calls must include the area code, even for local calls.

Foreign callers must replace the national trunk prefix with the international access code of their country (e.g., 00 from most countries, or 011 from the US/Canada) followed by 54 (the country code) and then the area code without the leading zero. For example, from the US, you would dial 011 54 3460 XXX XXX.

Overlay and Numbering Considerations

Currently, there is no overlay code in the 3460 area. The code is dedicated exclusively to the geographic region of Santa Teresa and its immediate surroundings. As part of Argentina's migration to a unified 10-digit dialing system, all numbers under this code are now required to be dialed with the area code, regardless of the caller's location within the country.

For businesses and residents in the area, it is essential to update any printed materials or online listings to reflect the full national format, including the area code, to ensure seamless connectivity.
