📍 Geographic Location of Askersund
Geographic Coverage and Administrative Jurisdiction
The Swedish area code 0583 is a geographic National Destination Code (NDC) assigned to the locality of Askersund, situated in the historical province of Närke in Örebro County. The code serves the urban area and its immediate surroundings, including the central town of Askersund and adjacent rural communities. Administratively, the region falls under the jurisdiction of Askersund Municipality, which is part of the Örebro County administrative board. The numbering area is defined by the Swedish Post and Telecom Authority (PTS) and is used for fixed-line PSTN and VoIP services that are geographically tied to this region.
Primary Cities and Local Dialing
The primary locality served is Askersund, a small town with a population of approximately 4,000 inhabitants. The code also covers nearby smaller settlements such as Åsbro, Hammar, and Zinkgruvan. For local calls within the 0583 area, subscribers can dial the seven-digit local number without the area code. For example, a local call to a subscriber number 123 45 67 would be dialed as 123 45 67.
International and National Dialing Formats
For callers from other parts of Sweden, the full national number must be dialed: 0583-XXX XX XX (where X represents digits). For international callers, the Swedish country code +46 is used, and the leading zero of the area code is omitted. Thus, a call from abroad to the same number would be dialed as +46 583 XXX XX XX. It is important to note that the area code is an essential part of the number for routing calls correctly within the Swedish PSTN.
Overlay Considerations and Numbering Plan
Currently, there is no overlay code for the 0583 area; the code is exclusively used for Askersund and its vicinity. The number length is fixed at seven digits for local subscriber numbers, making the total national significant number (NSN) length nine digits (including the leading zero). Sweden's numbering plan is regulated under the ITU-T E.164 recommendation, and the PTS ensures that geographic codes are assigned to specific regions to maintain routing efficiency.
