Area Code 45 – Paraná

Overview of Area Code 45 (Brazil)

Area code 45 is a geographic National Destination Code (NDC) assigned to the western and southwestern regions of the state of Paraná, Brazil. It falls under the country's +55 international calling code and is used for fixed-line (PSTN) and some mobile services within its coverage area. The code is administered by the National Telecommunications Agency (ANATEL) and serves a mix of urban and rural communities, including important agricultural and industrial hubs.

Coverage Area and Main Cities

The 45 area code covers a broad territory that includes the following key municipalities:

• Foz do Iguaçu – a major tourist destination, home to the Iguaçu Falls and the Itaipu Dam.
• Cascavel – a significant economic center for agribusiness and commerce.
• Toledo – known for its strong agricultural and food processing industries.
• Marechal Cândido Rondon – a hub for agro-industrial activities.
• Francisco Beltrão – a regional center in the southwestern part of the state.
• Pato Branco – another important city in the south, with growing technology and education sectors.

In addition to these, the code serves numerous smaller towns and rural areas, making it one of the more extensive geographic codes in Paraná.

Dialing Formats and Instructions

For local calls within the same area code, Brazilian fixed-line subscribers typically dial only the eight-digit local number (e.g., 3521-0000). However, for calls from a mobile phone, the full national format is often required, including the area code: 45 3521-0000.

For long-distance calls within Brazil from another area code, dial: 0 + operator code + 45 + local number. For example, from São Paulo (11) to a number in Cascavel, you would dial 0 15 45 3521-0000 (using operator 15).

For international calls to a number in the 45 area code, dial your country's exit code, then 55 (Brazil's country code), then 45, and the local eight-digit number. For instance, from the United States, you would dial 011 55 45 3521-0000. From a mobile phone, you may need to use the plus sign: +55 45 3521-0000.

Overlay and Numbering Considerations

Currently, there is no overlay code for the 45 region; it remains the sole area code for this geographic area. However, due to increasing demand, ANATEL has implemented measures to ensure number availability, and some mobile numbers within this code may have nine digits (starting with 9) as per Brazil's mobile numbering plan. Fixed-line numbers are eight digits and typically begin with digits 3, 4, or 5.

It is important to note that while area code 45 is primarily geographic, some mobile numbers are also assigned to this code, but they are non-geographic in nature and can be ported to other regions. When dialing a mobile number, you must always include the area code, even for local calls, as per Brazilian regulations.
