Local callers within Enköping can often dial the six-digit subscriber number directly without the area code, depending on their telephone exchange configuration. However, for clarity and to avoid misdialing, it is recommended to always include the area code when dialing from a mobile phone or from another region.
International callers should note that the leading zero is omitted when dialing from abroad. Ensure you have the correct country code and area code to reach Enköping landlines. Mobile numbers in Sweden are non-geographic and begin with other prefixes (e.g., 70, 72, 73), so they are not affected by this area code.
Regulatory and Technical Notes
The 171 prefix is administered by the Swedish Post and Telecom Authority (PTS) as part of the national numbering plan. It is a geographic code, meaning that calls are routed based on the physical location of the line. As of the latest updates, there are no overlay codes or 8-digit subscriber numbers in this area; the subscriber number length is fixed at six digits. Number portability allows subscribers to retain their numbers when switching operators, but the geographic significance of the code remains tied to the original location.
For businesses, having a 171 number establishes a local presence in Enköping, which can be beneficial for customer trust and local marketing. VoIP services may also offer numbers with this prefix, but they are subject to the same routing rules as traditional PSTN lines.
