Area Code 522 – Uddevalla

Overview of Area Code 522 (Uddevalla, Sweden)

Area code 522 is a geographic National Destination Code (NDC) within the Swedish national numbering plan, assigned to the municipality of Uddevalla and its surrounding localities in Västra Götaland County, on the west coast of Sweden. This code is part of the legacy PSTN (Public Switched Telephone Network) structure, originally allocated to fixed-line services, though it is also used for VoIP and other fixed-wireline services that retain geographic numbering.

Geographic Coverage and Administrative Jurisdiction

The 522 code serves the urban area of Uddevalla, the administrative seat of Uddevalla Municipality, along with nearby communities such as Ljungskile, Munkedal, and parts of the Orust and Tjörn archipelago areas. The region is characterized by a mix of residential, commercial, and industrial zones, with a population of approximately 55,000 in the municipality. As a geographic code, the prefix is tied to a specific rate center, which historically determined local call charging and routing.

Dialing Formats and Caller Instructions

For domestic callers within Sweden, the national format requires dialing the trunk prefix 0 followed by the area code and the subscriber number. For example, to call a fixed line in Uddevalla, you would dial: 0 522 XXXXX (where XXXXX is the 5-digit local subscriber number). The complete national number length is 8 digits (excluding the leading 0), which is standard for Swedish geographic numbers.

For international callers, the format is: +46 522 XXXXX (or 0046 522 XXXXX from countries using international prefix 00). The leading zero of the trunk prefix is omitted when dialing from abroad. For instance, a caller from the United States would dial 011 46 522 XXXXX, while a caller from the UK would dial 00 46 522 XXXXX.

Overlay and Numbering Plan Considerations

Sweden has not implemented overlay area codes for geographic numbering; instead, the country uses a closed numbering plan with variable NDC lengths. The 522 code is not subject to any overlay, and subscriber numbers within this area are typically 5 to 7 digits long, depending on the specific exchange. However, due to number portability, a subscriber may retain a 522 number even if they move outside the geographic area, which can lead to non-local routing. Callers should be aware that the prefix does not guarantee the physical location of the line, but it does indicate the original rate center.

Caller Guidance

Local callers within the same rate center may be able to dial just the subscriber number (without the area code) in some legacy exchanges, but modern Swedish networks generally require full national dialing (0 522 XXXXX) for all calls, including local ones, due to the implementation of mandatory 8-digit dialing. For international callers, it is essential to use the correct country code (+46) and to drop the leading zero. Always verify the number length, as some numbers may have additional digits for special services.
