📍 Geographic Location of Strängnäs
Overview of Area Code 152
Area code 152 is a geographic National Destination Code (NDC) within the Swedish national numbering plan, allocated under the international country calling code +46. It serves the municipality of Strängnäs, located in the historical province of Södermanland in south-central Sweden. The code covers the administrative seat of Strängnäs and its surrounding localities, including Åkers Styckebruk, Stallarholmen, and Mariefred, as well as the rural areas along the shores of Lake Mälaren. Geographically, it falls within the eastern part of the Södermanland County, approximately 60 kilometers west of Stockholm.
Dialing Formats
For domestic calls within Sweden, subscribers dial the trunk prefix 0 followed by the area code and the subscriber number. The national format is 0152-XXXXX, where the subscriber number typically consists of five to seven digits. For example, a local number in Strängnäs might be 0152-123 45. When calling from abroad, the trunk prefix is omitted, and the country code is used: +46 152 XXXXX (or 0046 152 XXXXX). It is important to note that the leading zero of the area code is only used in domestic dialing and must be dropped for international calls.
Local and International Caller Instructions
Local callers within the 152 area code can often dial just the subscriber number without the area code, depending on their operator's settings. However, for clarity and to avoid misdialing, it is recommended to use the full national format. For callers from other Swedish regions, dial 0152 followed by the subscriber number. International callers should dial their international exit code (e.g., 00 from most countries, or + from mobile phones), then 46, then 152, and finally the subscriber number. No additional codes are required.
Overlay and Numbering Considerations
As of the latest ITU-T E.164 updates, there is no overlay code for the 152 area. The Swedish Post and Telecom Authority (PTS) has not introduced any overlay plans for this region, meaning that the 152 code remains the sole geographic code for Strängnäs. Subscriber numbers within this code are allocated to fixed-line services, including PSTN and VoIP, but number portability allows users to retain their numbers when switching operators or technologies. However, the geographic association of the code remains tied to the Strängnäs area for routing and emergency services purposes.
