Area Code 341 – Rosario, Santa Fe

Overview of Argentina's +54 341 Area Code

Area code 341 is a geographic National Destination Code (NDC) assigned to the city of Rosario and its surrounding metropolitan area in the province of Santa Fe, Argentina. As part of the national numbering plan administered under ITU-T E.164 guidelines, this code routes calls to fixed-line (PSTN) subscribers within the designated geographic region. Rosario is Argentina's third most populous city and a major economic hub, which makes the 341 code essential for businesses and residents in the region.

Geographic Coverage and Jurisdiction

The 341 area code covers the Gran Rosario metropolitan area, which includes the city of Rosario and adjacent localities such as Funes, Roldán, Pérez, and Villa Gobernador Gálvez. The region is part of the southern zone of Santa Fe Province and is governed by the Ente Nacional de Comunicaciones (ENACOM), Argentina's national telecommunications regulator. The code is classified as a geographic allocation, meaning that the numbering resource is tied to a specific physical area, although modern fixed-line services may also be delivered over VoIP infrastructure.

Dialing Formats and Procedures

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

• Local calls (within Rosario): Dial the 7-digit subscriber number directly. For example, to reach a local number 456-7890, dial 456-7890.
• National calls (from other Argentine cities): Dial the national trunk prefix 0, followed by the area code 341 and the subscriber number. For instance, from Buenos Aires, dial 0-341-456-7890.
• International calls (from outside Argentina): Dial the international access prefix (e.g., 00 from most countries), then Argentina's country code 54, followed by the area code (without the leading 0) and the subscriber number. For example, from the United States, dial 011-54-341-456-7890.

Note that the trunk prefix '0' is used only for domestic long-distance dialing and is not included when dialing from abroad.

Overlay and Numbering Considerations

Currently, there is no overlay code for the 341 area; the region uses a single geographic code. However, as with all Argentine fixed-line numbers, subscribers may have the option to retain their number when switching providers (local number portability). The 7-digit subscriber numbers are unique within the 341 area, and the total length of a national significant number (NSN) is 10 digits (area code + subscriber number).

Practical Guidance for Callers

For local callers within Rosario, omitting the area code is acceptable for local calls. For international callers, always ensure you drop the leading '0' of the area code. If you are using a mobile phone in Argentina, you may need to include the area code even for local calls, depending on your carrier's settings. Always verify the complete number before dialing to avoid misrouted calls.
