Geographic Significance

Köttmannsdorf lies just south of the Carinthian capital Klagenfurt, and its telephone numbering is integrated into the regional numbering plan. The 4220 prefix is part of the larger Klagenfurt telephony region, but it is distinct from the Klagenfurt city code (0463). This distinction ensures that calls are routed efficiently to the correct local exchange. The area is known for its scenic landscape and proximity to Lake Wörthersee, but the telephone code itself is purely geographic and does not imply any special service features.

Caller Instructions

For local callers within Austria, always include the trunk prefix '0' before the area code when dialing from a different fixed or mobile network. For international callers, replace the '0' with the +43 country code. If you are calling from a mobile phone within Austria, you may need to include the area code even if you are in the same region, as mobile networks do not automatically recognize local numbers without the full national format. Always verify the subscriber number length, as some numbers may have fewer digits.

Regulatory and Technical Notes

As a geographic code, +43 4220 is subject to Austrian numbering regulations under the national regulatory authority, RTR (Rundfunk und Telekom Regulierungs GmbH). Number portability applies, meaning that a subscriber may retain their 4220 number even if they move to a different operator, but the number remains tied to the geographic location. VoIP services may also use this code, but they are required to provide location information for emergency calls. There are no overlay codes currently assigned to this area, so the 4220 prefix is unique for this region.
