📍 Geographic Location of Oskarshamn-Högsby
Geographic Coverage and Administrative Jurisdiction
The Swedish area code 491 is a geographic National Destination Code (NDC) assigned to the eastern part of Småland, specifically the municipalities of Oskarshamn and Högsby. This region falls under Kalmar County and includes localities such as Oskarshamn, Högsby, Figeholm, Påskallavik, and Kristdala. The code serves both urban and rural subscribers connected to the traditional Public Switched Telephone Network (PSTN) and Voice over IP (VoIP) services that retain geographic numbering.
Dialing Formats and Procedures
When calling a subscriber within the 491 area from another part of Sweden, you must use the trunk prefix 0 followed by the area code and the subscriber's local number. The national format is: 0 491 XX XX XX. However, if you are dialing from a phone located within the same 491 area, you can often omit the trunk prefix and area code and simply dial the local 6-digit subscriber number. For international callers, the format is: +46 491 XX XX XX (or 0046 491 XX XX XX from many countries). The leading '0' is dropped when using the international prefix. For example, a local number 12 34 56 would be dialed as 0491 12 34 56 nationally and +46 491 12 34 56 internationally.
Number Structure and Overlays
Swedish geographic numbers typically consist of 6 to 8 digits after the area code. In the 491 area, subscriber numbers are 6 digits long, giving a total national significant number length of 9 digits (including the leading '0' for domestic calls). There are no overlay codes in this region; the 491 code is exclusively used for the Oskarshamn-Högsby area. If you are moving within the same area, your number can usually be retained, but if you relocate outside the 491 area, you may need to obtain a new number with the appropriate local area code.
Caller Instructions and Considerations
For local callers within the 491 area, using the short dialing format (without the area code) is common for landline-to-landline calls. However, for mobile phones, it is always recommended to dial the full national number (0491 XX XX XX) to ensure proper routing. For foreign callers, always use the international format +46 491 XX XX XX. Be aware that calls to Swedish geographic numbers are typically charged at standard national rates, which may vary depending on your telecom provider. If you are using VoIP services, ensure that your provider supports calls to Swedish geographic numbers and that you have correctly configured the dialing prefix.
