📍 Geographic Location of Kungsbacka
Overview of Area Code 300 (Kungsbacka, Sweden)
Area code 300 is a geographic National Destination Code (NDC) assigned to the municipality of Kungsbacka in Halland County, on Sweden's west coast. It covers the urban center of Kungsbacka and its surrounding localities, including Onsala, Åsa, and Fjärås. The code is part of the Swedish national numbering plan under the +46 country calling code, administered by the Swedish Post and Telecom Authority (PTS).
Dialing Formats
For callers within Sweden, the national trunk prefix 0 is used before the area code. Thus, a local number is dialed as 0300-XX XX XX (where X represents the subscriber digits). Internationally, callers must replace the leading zero with the country code, resulting in +46 300 XX XX XX or +46300XXXXXX when dialed without spaces. The total number length, including the country code, is typically 12 digits (excluding the plus sign).
Geographic Coverage and Administration
Kungsbacka is situated just south of Gothenburg, and the area code 300 is exclusively used for fixed-line (PSTN) and fixed-wireless services within the municipality. The region is part of the Västra Götaland County's economic sphere, and many residents commute to Gothenburg for work. The numbering area is not overlaid with another area code; therefore, local calls within the 300 area do not require the area code, but calls from other Swedish regions must include the trunk prefix and area code.
Caller Instructions
- Local callers (within 300): Dial the 6- or 7-digit subscriber number directly (e.g., 12 34 56).
- National callers (outside 300): Dial 0300 followed by the subscriber number (e.g., 0300-12 34 56).
- International callers: Dial your country's exit code, then 46 (Sweden's country code), then 300 without the leading zero, and the subscriber number (e.g., +46 300 12 34 56).
Numbering and Portability
Subscriber numbers within area code 300 are typically 6 to 7 digits long, depending on the exchange. As with all Swedish geographic numbers, number portability is available, allowing users to retain their numbers when switching operators, but the geographic significance is preserved. VoIP services may also use geographic numbers, but the physical location of the caller is not necessarily tied to the area code.
