Area Code 3454 – Federal, Entre Ríos

Overview of Area Code 3454

Area code 3454 is a geographic National Destination Code (NDC) within the Argentine national numbering plan, assigned to the Federal District of Entre Ríos Province. It serves the central-western region of Entre Ríos, covering the department of Paraná and its surrounding localities. The principal city served is Paraná, the provincial capital, along with adjacent towns such as San Benito, Colonia Avellaneda, and Villa Urquiza. This area code is part of the E.164 international dialing scheme under the country code +54 for Argentina.

Geographic Coverage and Administrative Jurisdiction

The 3454 code is administered under the federal jurisdiction of Entre Ríos Province, which is part of the Argentine Republic. The region is characterized by its administrative and political significance, as Paraná serves as the seat of the provincial government. The coverage area includes both urban and rural zones, with the Paraná River forming the western boundary of the province. This geographic allocation is fixed, meaning that the code is tied to the physical location of the telephone line, as per the national numbering plan.

Dialing Formats and Procedures

For callers within Argentina, the national dialing format requires the use of the trunk prefix 0 followed by the area code and the subscriber number. For example, to call a landline in Paraná from another Argentine city, you would dial: 0 3454 XXX XXX (where X represents the 6- or 7-digit local subscriber number). For international callers, the format is +54 3454 XXX XXX, omitting the trunk prefix. Local calls within the same area code can be made using the 6- or 7-digit subscriber number directly, without the area code.

It is important to note that Argentina has implemented overlay codes in some regions, but as of the current numbering plan, 3454 does not have an overlay. Therefore, the area code remains mandatory for all calls originating from outside the local calling area. For callers using mobile phones, the same international and national formats apply, but mobile numbers are non-geographic and have their own prefixes (e.g., 11, 223, etc.).

Caller Instructions

For local callers within the 3454 area, simply dial the subscriber number. For domestic long-distance callers, always include the trunk prefix 0 and the area code. For foreign callers, the international access code of their country (e.g., 00 from many countries, or 011 from the United States) must be used before the country code 54. Example: from the US, dial 011 54 3454 XXX XXX. From a mobile phone, replace the international access code with the plus sign: +54 3454 XXX XXX.

This area code is exclusively for fixed-line services, and it is not used for mobile or VoIP services, which have their own non-geographic numbering ranges. As such, the code is not subject to mobile number portability, but fixed-line number portability may apply within the same geographic area.
