📍 Geographic Location of Falun
Geographic Overview
The Swedish area code 23 is a geographic National Destination Code (NDC) assigned to the Falun region, located in the heart of Dalarna County in central Sweden. Falun is the administrative seat of Dalarna and is historically renowned for its copper mining heritage, now a UNESCO World Heritage site. The code covers the municipality of Falun and its immediate surroundings, including the urban area of Falun, the town of Borlänge is not included (it uses 243), but nearby localities such as Svärdsjö, Enviken, and Bjursås fall within this numbering area.
Dialing Formats
When calling a landline in Falun from within Sweden, the national trunk prefix 0 is used, followed by the area code and the subscriber number. The local subscriber numbers in this area are typically 5 to 7 digits long, making the total national significant number (NSN) length 8 to 9 digits (excluding the leading 0). For example, a local number might be 023-XXX XX when written in the local format.
From abroad, callers must use the international prefix (00 or +) followed by Sweden's country code 46, then the area code 23 without the leading 0, and then the subscriber number. For instance, to call a Falun number with the local number 123 45 67, you would dial +46 23 123 45 67.
Geographic Allocation and Numbering
According to the Swedish Post and Telecom Authority (PTS), area code 23 is part of the national numbering plan that follows ITU-T E.164 recommendations. The code is geographically allocated, meaning that the call routing is based on the physical location of the fixed-line exchange. This is distinct from mobile or non-geographic numbers, which are not tied to a specific region.
Overlays and Number Portability
As of the latest PTS updates, there is no overlay code for the Falun area; the 23 code remains the sole geographic code for this region. However, fixed-line number portability is available in Sweden, allowing subscribers to retain their numbers when changing operators, but the geographic significance of the code remains unchanged.
Caller Instructions
- Local callers within the Falun area can often dial the subscriber number directly without the area code, depending on the specific local dialing rules. However, it is always safe to include the area code (023) for calls from other parts of Sweden.
- International callers must replace the leading 0 with the +46 country code, as shown in the example above.
- Emergency services (112) are always reached without any area code.
Understanding the correct dialing format is essential for both business and personal communication, ensuring seamless connectivity to this historic Swedish region.
