Area Code 2489 – Sukagawa, Fukushima

Geographic Context and Coverage

Area code 2489 is a geographic National Destination Code (NDC) within the Japanese numbering plan, allocated to the city of Sukagawa and its surrounding areas in Fukushima Prefecture, located in the Tōhoku region of Honshu. This code covers the administrative jurisdictions of Sukagawa city, along with parts of the neighboring towns and villages that fall within the traditional telephone exchange area. The region is known for its agricultural production and the historic Sukagawa district, which is a local administrative and commercial hub.

Dialing Formats and Instructions

When calling a landline in Sukagawa from within Japan, you must dial the area code followed by the subscriber number. The area code is typically dialed as 02489, omitting the trunk prefix 0 when dialing internationally. The full national number consists of the area code (including the leading 0) plus a local subscriber number, resulting in a total of 10 digits (e.g., 02489-XXXXXX). For international callers, the format is +81 2489 XXXXXX, where the leading zero of the area code is dropped.

For example, to call a Sukagawa number from abroad, you would dial: +81 2489 123456. If you are calling from a mobile phone within Japan, you can generally dial the number directly using the same national format. However, if you are calling from a landline in a different area code, you must include the trunk prefix 0 before the area code: 02489-123456.

Numbering and Overlay Considerations

As of the current numbering plan, there are no overlay codes in this region, meaning that the 2489 area code is unique to the Sukagawa area. The subscriber numbers are typically six digits long, but the total length of the national significant number (NSN) is ten digits, including the leading zero of the area code. This is standard for Japanese geographic numbers.

Caller Instructions

For local callers within the same area code, it is sometimes possible to dial only the subscriber number without the area code, but this practice is becoming less common with the proliferation of VoIP and mobile services. To avoid confusion, it is recommended to always dial the full national number, including the area code, when calling from any phone. For international callers, ensure you use the correct country code (+81) and drop the leading zero of the area code.

This area code is part of the public switched telephone network (PSTN) and is also used by VoIP providers that offer geographic numbers. When calling from abroad, be aware of time zone differences (Japan Standard Time, UTC+9) and potential charges associated with international calls.
