Area Code 456 – Sölvesborg-Bromölla

Overview of Area Code 456 (Sölvesborg-Bromölla)

Area code 456 is a geographic National Destination Code (NDC) within the Swedish national numbering plan, allocated under the international country calling code +46. It serves the southeastern region of Sweden, specifically the municipalities of Sölvesborg and Bromölla, both located in Blekinge County (Blekinge län). This area is part of the historical province of Blekinge, known for its coastal landscape along the Baltic Sea.

Geographically, the code covers a mix of urban and rural areas. Sölvesborg, the administrative seat of Sölvesborg Municipality, is the largest locality in the area, while Bromölla is a smaller industrial town known for its ceramics and stone industries. The code also includes smaller communities and surrounding countryside.

Dialing Formats

For domestic callers within Sweden, the area code is dialed with a leading zero: 0456 followed by the subscriber number. The national significant number (NSN) for this area is 8 digits long, comprising the area code (without the leading zero) and a 5-digit local subscriber number. For example, a typical local number might be 0456-12345.

For international callers, the format is +46 456 12345 (or +4645612345 when dialed without spaces). The leading zero is omitted, and the plus sign represents the international access prefix. From most countries, you would dial your international exit code (e.g., 00 from Europe, 011 from North America), followed by 46, then 456, and the subscriber number.

Geographic Coverage and Administration

The 456 area code is administered by the Swedish Post and Telecom Authority (PTS), which oversees the national numbering plan in compliance with ITU-T E.164 recommendations. The code is designated for fixed-line services, including PSTN and VoIP services that are geographically tied to the region. However, with number portability, a subscriber may retain their 456 number even if they move to a different geographic area or switch to a VoIP provider, though the number remains associated with the original geographic location for routing purposes.

There are no overlay codes currently in effect for this area; 456 serves as the sole area code for Sölvesborg and Bromölla. Local calls within the same area code do not require the area code, but for clarity and due to number portability, it is often recommended to dial the full national number (including the area code) even for local calls.

Caller Instructions

For local callers within the 456 area, dialing the 5-digit subscriber number is sufficient for calls to other numbers within the same area code. For calls to other Swedish area codes, dial the full national number starting with 0 (e.g., 0456-XXXXX). For foreign callers, always use the international format +46 456 XXXXX, ensuring you drop the leading zero of the area code.

When calling from a mobile phone, the same rules apply; the plus sign can be used to initiate international calls. It is also important to note that calls to Swedish geographic numbers from abroad are typically charged at international rates, which vary by carrier.
