📍 Geographic Location of Vadstena
Geographic Overview
The Swedish area code 143 is a geographic National Destination Code (NDC) assigned to the town of Vadstena and its surrounding administrative area in Östergötland County. Vadstena, situated on the eastern shore of Lake Vättern, is part of the historic province of Östergötland and serves as the seat of Vadstena Municipality. The code covers the urban center as well as nearby localities such as Borghamn, Väversunda, and Herrestad. This numbering area is part of the national Swedish telephony plan administered by the Swedish Post and Telecom Authority (PTS).
Dialing Formats
When calling a landline in the Vadstena area from within Sweden, the national trunk prefix 0 is used, followed by the area code and the local subscriber number. The complete national format is 0 143 X XX XX, where the subscriber number typically consists of five to six digits. For example, a local number might be dialed as 0143 123 45 from any phone in Sweden.
For international callers, the Swedish country code +46 replaces the leading zero, and the area code is used without the trunk prefix. Thus, the international format becomes +46 143 X XX XX. For instance, a caller from abroad would dial +46 143 123 45 to reach the same subscriber.
Caller Instructions
Local callers within the Vadstena area may be able to dial only the subscriber number for calls within the same exchange, depending on the operator's configuration. However, for calls from other parts of Sweden, the full national format with the trunk prefix is required. Foreign callers must always include the country code and omit the trunk prefix. It is important to note that Sweden has implemented number portability, so a subscriber may retain their number when switching operators, but the geographic significance of the code remains tied to the original location.
Overlays and Regulatory Notes
As of the latest PTS numbering plan, there are no overlay codes for the 143 area; the code is exclusively assigned to the Vadstena geographic region. The code is used for fixed-line services, and while VoIP services may use geographic numbers, they are subject to the same dialing rules. The Swedish numbering plan follows ITU-T E.164 recommendations, ensuring global interoperability.
