Caller Instructions
- Local callers within the Köping area may sometimes omit the area code for local calls, depending on their operator, but it is recommended to always include the full national number to avoid misrouting.
- Domestic long-distance callers from other Swedish regions must dial 0221 followed by the subscriber number.
- International callers should dial their international exit code (e.g., 00 from most countries, or + from mobile), then 46, then 221, and finally the subscriber number, omitting the leading zero.
Numbering and Overlay Considerations
Sweden's numbering plan follows ITU-T E.164 recommendations. The area code 221 is part of the closed numbering plan where the total national significant number length is typically 8 to 9 digits (including the leading 0). No overlay codes have been introduced for this region; the 221 code remains exclusive to the geographic area. As of the latest regulatory updates, there are no plans to change the geographic boundaries or introduce additional area codes for Köping.
All fixed-line numbers in this area are allocated to local incumbent operators and alternative carriers, but number portability allows subscribers to retain their numbers when switching providers. However, the geographic significance of the code remains, and it is used for routing calls based on physical location.
