Area Code 3476 – San Lorenzo, Santa Fe

Overview of Area Code 3476

Area code 3476 is a geographic National Destination Code (NDC) assigned to the city of San Lorenzo and its surrounding localities in the southern part of Santa Fe Province, Argentina. This region forms part of the broader Rosario metropolitan area, strategically located along the Paraná River. The code serves a mix of urban and semi-rural communities, including Puerto General San Martín, Ricardone, and Fray Luis Beltrán, among others. Administratively, the area falls under the jurisdiction of the San Lorenzo Department.

Dialing Formats

When calling a fixed-line number in this region, the number format depends on the caller's origin:

• Local calls (within the same area code): Dial the 7-digit subscriber number directly. For example, to reach a local line, dial 456-7890.
• National calls (from other Argentine provinces or cities): Dial 0 (trunk prefix) followed by 3476 and the 7-digit subscriber number. Example: 0-3476-456-7890.
• International calls (from outside Argentina): Dial the international access code (e.g., 00 from most countries), then 54 (Argentina's country code), then 3476 and the subscriber number. Example: +54 3476 456-7890.

Geographic Coverage and Significance

The 3476 area code is part of the National Numbering Plan under ITU-T E.164. It is a geographic code, meaning the number is tied to a physical location. San Lorenzo is historically significant as the site of the Battle of San Lorenzo (1813), and today it hosts important industrial and port activities, particularly related to agrochemicals and grain exports. The area's proximity to Rosario (area code 341) and its connection via major highways make it a key logistics hub.

Overlay and Numbering Considerations

As of the latest updates, there is no overlay code for 3476; the area operates with a single NDC. However, the National Communications Entity (ENACOM) periodically reviews numbering resources, so future changes are possible. For callers, it is essential to use the correct prefix when dialing from outside the area to avoid misrouting. For businesses, having a local presence in San Lorenzo can be enhanced by obtaining a fixed-line number with this code, which signals geographic stability and local commitment.

Practical Tips for Callers
