📍 Geographic Location of Valdemarsvik
Geographic Overview
The Swedish area code 123 is a geographic National Destination Code (NDC) assigned to the locality of Valdemarsvik, located in the eastern part of the Östergötland County, on the Baltic Sea coast. This code covers the municipality of Valdemarsvik and its surrounding rural areas, including smaller communities such as Gusum and Ringarum. The region is known for its coastal archipelago and forestry, and the code serves both residential and business fixed-line subscribers within this defined geographic area.
Dialing Formats
When calling a Valdemarsvik number from within Sweden, the trunk prefix 0 is used before the area code, followed by the subscriber number. The local subscriber numbers in this area typically consist of 5 to 7 digits, resulting in a total national significant number length of 8 to 9 digits (excluding the trunk prefix). For example, a local number might be 0123-123 45 when dialed domestically.
From abroad, callers must use the international prefix (usually + or 00), followed by Sweden's country code 46, then the area code 123 without the leading zero, and finally the subscriber number. For instance, to call a Valdemarsvik number from the United States, you would dial 011 46 123 123 45 or +46 123 123 45 from a mobile phone.
Local and International Caller Instructions
For local callers within the Valdemarsvik area, it is possible to dial just the subscriber number without the area code for calls within the same geographic exchange. However, due to number portability and the possibility of overlay, it is always safer to include the area code even for local calls. For international callers, it is essential to drop the leading zero of the area code when adding the country code. The same applies when sending SMS or fax to a Valdemarsvik fixed-line number.
Regulatory and Technical Notes
Sweden's numbering plan is regulated by the Swedish Post and Telecom Authority (PTS). The area code 123 is part of the closed numbering plan where the trunk prefix 0 is used for domestic calls.
