📍 Geographic Location of Paraná
Geographic Coverage and Administrative Jurisdiction
Area code 46 is a geographic National Destination Code (NDC) within the Brazilian telephone numbering plan, assigned to the southwestern and southern mesoregions of the state of Paraná. It serves a territory that borders Argentina to the south and Santa Catarina to the east, encompassing the municipalities of Pato Branco, Francisco Beltrão, Dois Vizinhos, Palmas, Clevelândia, Coronel Vivida, and Chopinzinho, among others. The code is administered under the regulatory oversight of ANATEL (Agência Nacional de Telecomunicações) and is allocated to both fixed-line (PSTN) and VoIP services within this geographic area.
Primary Cities and Service Areas
The most populous city within code 46 is Pato Branco, an important industrial and agribusiness hub. Francisco Beltrão is another major urban center, serving as a regional health and education reference. Other notable municipalities include Dois Vizinhos, known for its poultry and swine production, and Palmas, which lies on the border with Santa Catarina. The region is characterized by a mix of urban centers and rural zones, with the code covering a population of approximately 800,000 inhabitants.
Dialing Formats and Caller Instructions
For local calls within the same area code, subscribers must dial the 8-digit subscriber number (e.g., 3521-1000). For calls from other Brazilian area codes, the format is 0 + operator code (XX) + 46 + subscriber number (e.g., 0 15 46 3521-1000). International callers must dial the Brazilian country code +55, followed by the area code 46 and the subscriber number, omitting the trunk prefix: +55 46 3521-1000. It is important to note that Brazil uses a two-stage dialing system for domestic long-distance calls, requiring the selection of a long-distance carrier (e.g., Embratel, Vivo, Oi) via the operator code. Since 2012, ANATEL has implemented the 8th digit for fixed-line numbers in many areas, but code 46 still uses 8-digit numbers without an extra digit.
Overlay and Numbering Considerations
As of the latest ANATEL updates, area code 46 does not have an overlay code, meaning it is the sole geographic code for the region. However, due to the growing demand for telecommunication services, ANATEL periodically reviews numbering allocation. Subscribers in the region may also have access to VoIP services that use the same geographic code, as mandated by ANATEL's regulation for fixed-line services. When dialing from a mobile phone within Brazil, the same long-distance rules apply, but mobile-to-mobile calls may require the addition of the digit '9' before the subscriber number only when calling mobile numbers (which are not part of this geographic code). For fixed-line numbers in code 46, the 8-digit format remains standard.
