📍 Geographic Location of Ulricehamn
Geographic Overview
The Swedish area code 321 is a geographic National Destination Code (NDC) assigned to the town of Ulricehamn and its surrounding municipalities in the Västra Götaland County, western Sweden. Ulricehamn is located approximately 100 km east of Gothenburg, near the shores of Lake Åsunden. The code covers the urban area and several smaller localities within the Ulricehamn Municipality, including Timmele, Hökerum, and Blidsberg. As a geographic code, 321 is tied to the PSTN (Public Switched Telephone Network) and is used for fixed-line services, though some VoIP providers may also allocate numbers with this prefix.
Dialing Formats
When calling a Ulricehamn number from within Sweden, you must use the national trunk prefix 0 followed by the area code and the subscriber number. For example, a local number might be dialed as 0321-XXXXX. From abroad, you would dial the international access code (e.g., 00 from most countries), then Sweden's country code +46, followed by the area code without the leading zero, and the subscriber number: +46 321 XXXXX. It is important to note that the subscriber number length in the 321 area is typically 5 to 7 digits, making the total national significant number (NSN) length 8 to 10 digits, in accordance with the Swedish National Numbering Plan.
Caller Instructions
For local callers within the Ulricehamn area, it is possible to dial just the subscriber number for calls within the same exchange, but for calls from other parts of Sweden, the full national format 0321-XXXXX is required. International callers should always use the international format +46 321 XXXXX to ensure proper routing. If you are calling from a mobile phone within Sweden, you can use the national format with the leading zero. Remember that when dialing from abroad, the leading zero is omitted.
Regulatory and Technical Notes
The 321 area code is administered by the Swedish Post and Telecom Authority (PTS). As of recent years, there are no overlay codes for the Ulricehamn area, meaning that 321 remains the sole geographic code for this region. Number portability allows subscribers to keep their numbers when changing operators, but the geographic significance of the code is retained. For businesses, having a 321 number can establish a local presence in Ulricehamn, which may be beneficial for customer trust and local SEO. When dialing from abroad, be aware of time zone differences (Central European Time, UTC+1, UTC+2 in summer) to avoid calling at inconvenient hours.
