Area Code 3400 – Villa Constitución, Santa Fe

Overview of Area Code 3400

Area code 3400 is a geographic National Destination Code (NDC) assigned to the city of Villa Constitución and its surrounding localities in the southern part of Santa Fe Province, Argentina. This region lies along the Paraná River, near the border with Buenos Aires Province, and is an important industrial and agricultural hub. The code is used for fixed-line (PSTN) services within this specific geographic area.

Geographic Coverage and Jurisdiction

The 3400 code covers Villa Constitución and nearby towns such as Pavón, Peyrano, Rueda, and Santa Teresa. Administratively, these localities fall under the jurisdiction of the Constitución Department in Santa Fe Province. The region is known for its steel production and river port activities, which influence the demand for reliable telecommunications services.

Dialing Formats and Instructions

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

• Local Calls (within the 3400 area): When calling from one fixed-line number to another within the same area code, you typically dial the 7-digit subscriber number directly. For example, to call a local number 456-7890, you would dial 456-7890.
• National Long-Distance Calls (from other Argentine cities): Dial the national trunk prefix 0, then the area code 3400, followed by the 7-digit subscriber number. For instance, from Buenos Aires, you would dial 0-3400-456-7890.
• International Calls (from outside Argentina): Dial your country's international exit code (e.g., 011 from the US, 00 from most European countries), then Argentina's country code 54, then the area code 3400 (without the leading 0), and finally the 7-digit subscriber number. For example, from the United States, you would dial 011-54-3400-456-7890.

Numbering Plan Considerations

Argentina's numbering plan is regulated by the Ente Nacional de Comunicaciones (ENACOM). The area code 3400 is part of the national numbering plan, and no overlay codes have been introduced in this region. Therefore, the area code is mandatory for all calls originating from outside the local calling area. Subscriber numbers within this code are 7 digits long, and the total length of an international number (country code + area code + subscriber number) is 13 digits, conforming to ITU-T E.164 standards.

Caller Instructions

• Local callers: If you are within the 3400 area, simply dial the 7-digit number for local calls. For calls to other areas, include the trunk prefix 0 and the destination area code.
• Foreign callers: Always omit the leading 0 of the area code when dialing from abroad. Ensure you have the correct international exit code for your country.

For businesses or individuals in Villa Constitución, having a local presence with a 3400 number is essential for establishing trust and accessibility within the community. As the region continues to develop, the demand for clear and reliable communication remains a priority.
