This region is characterized by its forested landscapes and proximity to the Orsa Finnmark area.

Dialing Formats

It is important to note that the area code is an integral part of the number and must be included even when dialing from a mobile phone within Sweden.
Geographic Coverage and Numbering
The 657 code is exclusively assigned to Los and its immediate surroundings. Subscriber numbers within this code typically consist of 6 to 7 digits after the area code, conforming to the Swedish national numbering plan. The code is part of the closed numbering plan, meaning that the full national number (including the area code) must always be dialed for local calls.
Overlays and Regulatory Notes
As of the current numbering plan, there are no overlay codes for the 657 area. The Swedish Post and Telecom Authority (PTS) manages the allocation of geographic codes, ensuring that each code corresponds to a specific geographic region. Number portability is available for fixed-line services, allowing subscribers to retain their numbers when changing operators within the same geographic area.
Caller Instructions
For local callers within Sweden, dial 0657 followed by the subscriber number. For international callers, dial your country's exit code (e.g., 00 from most European countries, 011 from North America), then 46, then 657, and finally the subscriber number. Always omit the leading zero of the area code when dialing from abroad. Example: To reach a Los subscriber with the local number 123 456, international callers would dial +46 657 123 456.
