Area Code 225 – Hedemora-Säter

Overview of Area Code 225 (Hedemora-Säter)

Area code 225 is a geographic National Destination Code (NDC) within the Swedish national numbering plan, assigned to the Hedemora-Säter telephone area in the southern part of Dalarna County (Dalarnas län). This region encompasses the municipalities of Hedemora and Säter, along with smaller localities such as Garpenberg, Långshyttan, and Vikmanshyttan. The code serves both residential and business fixed-line subscribers connected to the public switched telephone network (PSTN) and VoIP services that utilize geographic numbers.

Geographic Coverage and Administrative Jurisdiction

The 225 area code covers a historically significant mining and industrial district. Hedemora, the largest town, is known for its well-preserved wooden houses and as one of Sweden's oldest towns. Säter, located approximately 20 kilometers north of Hedemora, is a smaller municipality with a mix of rural and urban settlements. The area code boundary aligns with the municipal borders, ensuring that all fixed-line numbers within these municipalities share the same NDC.

Dialing Formats and Number Structure

Swedish geographic numbers consist of a variable-length NDC followed by a subscriber number. For area code 225, the subscriber number length is typically 5 to 6 digits, resulting in a total national (significant) number length of 8 to 9 digits. The international format, as defined by ITU-T E.164, is +46 225 XX XXX XX (or +46 225 XXX XXX for shorter subscriber numbers). When dialing within Sweden, callers must use the trunk prefix 0 before the area code: 0225 XX XXX XX. For example, a local call to a number in Hedemora would be dialed as 0225-XXXXX, while an international caller would dial +46 225 XXXXX.

Caller Instructions

• Local callers (within Sweden): Dial the trunk prefix '0' followed by the area code and subscriber number. Example: 0225 12345.
• International callers: Dial the international access prefix (e.g., 00 from most countries), then Sweden's country code 46, followed by the area code without the leading '0', and the subscriber number. Example: +46 225 12345.

Overlay and Number Portability Considerations

As of the current numbering plan, there is no overlay code for the 225 area. Subscribers may, however, port their numbers to other operators, including mobile and VoIP providers, while retaining the geographic number. This means that a call to a 225 number may terminate on a mobile network or an IP-based service, but the caller is not charged a premium rate; standard geographic call charges apply.

Regulatory and Technical Notes

The Swedish Post and Telecom Authority (PTS) administers the national numbering plan. Area code 225 is classified as a geographic number, meaning that the tariff is generally lower than calls to mobile or premium services. For businesses, having a 225 number establishes a local presence in the Hedemora-Säter area, which can be beneficial for customer trust and local marketing.
