Area Code 620 – Sollefteå

Overview of Area Code 0620

Area code 0620 is a geographic National Destination Code (NDC) within the Swedish national numbering plan, conforming to ITU-T E.164 standards. It serves the municipality of Sollefteå, located in Västernorrland County in the historical province of Ångermanland, in central Sweden. The code is assigned to the Sollefteå telephone exchange area and covers the town of Sollefteå as well as surrounding localities and rural areas within the municipality.

Geographic Coverage and Administrative Jurisdiction

The 0620 area code encompasses Sollefteå and its administrative boundaries, including nearby communities such as Junsele, Ramsele, and Långsele. The region is known for its scenic river valleys, forests, and outdoor recreation. As a geographic code, it is tied to the physical location of the subscriber's line, and calls to numbers within this code are routed through the public switched telephone network (PSTN) to the local exchange.

Dialing Formats

When dialing within Sweden, callers must use the national trunk prefix '0' followed by the area code and the subscriber number. For example, a local call to a subscriber in Sollefteå would be dialed as 0620-XXXXX, where 'XXXXX' represents the 5-digit local subscriber number. The complete national significant number (NSN) is 9 digits, including the leading '0' of the area code.

For international callers, the Swedish country code +46 is used, and the leading '0' of the area code is dropped. Thus, an international call to Sollefteå would be dialed as +46 620 XXXXX. For instance, if the local number is 12345, the international format is +46 620 12345.

Overlay and Numbering Considerations

As of the current numbering plan, there is no overlay code for the 0620 area. Subscribers in Sollefteå have 5-digit local numbers, and the area code is mandatory for all calls outside the local exchange area. The Swedish Post and Telecom Authority (PTS) administers the numbering plan, and number portability is available, meaning that a subscriber may retain their number when switching operators, but the geographic significance remains tied to the original exchange area.

Caller Instructions

• Local callers within Sollefteå: If you are calling from within the same exchange area, you may be able to dial only the 5-digit subscriber number (e.g., 12345). However, for clarity and to avoid misdialing, it is recommended to use the full national format.
• National callers from other parts of Sweden: Dial the trunk prefix '0', then the area code and subscriber number: 0620-XXXXX.
• International callers: Dial your country's exit code, then Sweden's country code 46, then the area code without the leading '0', and the subscriber number: +46 620 XXXXX.

Always verify the number length and format with your service provider, as mobile and VoIP services may have different dialing requirements.
