Area Code 2487 – Sukagawa, Fukushima

Overview of Area Code 2487

Area code 2487 is a geographic dialing code assigned to the city of Sukagawa and its surrounding areas within the Fukushima Prefecture of Japan. It forms part of the national numbering plan under the ITU-T E.164 standard, with the full international dialing format being +81 2487 XXXXX. This code is used for fixed-line (PSTN) services, including traditional analog lines, ISDN, and VoIP services that are registered to a physical address within the coverage area.

Geographic Coverage and Administrative Jurisdiction

The 2487 code covers the city of Sukagawa, which is located in the Nakadōri region of Fukushima Prefecture. Sukagawa serves as a commercial and administrative hub for the surrounding area, and the code also extends to parts of neighboring municipalities, including portions of Kōriyama and Tamura. The region is known for its agricultural production, particularly of peaches and rice, as well as its historical sites such as the Sukagawa Daibutsu (Great Buddha) and the annual Sukagawa Festival.

Dialing Formats and Caller Instructions

For local callers within Japan, the area code is dialed as 02487 followed by the subscriber number, which typically consists of 5 digits, resulting in a total national significant number length of 10 digits (excluding the trunk prefix 0). For example, a local call to a subscriber number 12345 would be dialed as 02487-12345 from within Japan.

International callers must dial the country code for Japan (+81), then the area code without the leading zero, and then the subscriber number. For instance, to call the same number from abroad, you would dial +81 2487 12345. It is important to note that the leading '0' in the national dialing format is a trunk prefix and is not included when dialing from outside Japan.

When calling from a mobile phone within Japan, the same national format (02487-XXXXX) is used. However, if you are calling from a foreign country, ensure you use the international format (+81 2487-XXXXX) and omit the initial '0'.

Overlay and Numbering Considerations

Currently, there is no overlay code for the 2487 area. The code is unique to the Sukagawa area, and no additional area codes have been assigned to this region. This means that local calls within the same area code do not require an area code, but for calls from outside the area, the full national number including the area code must be dialed.

As with all Japanese geographic numbers, the 2487 code is subject to number portability, allowing subscribers to retain their numbers when switching service providers, provided the new service is still within the same geographic area. However, the code itself is tied to the physical location, and numbers cannot be moved outside the designated region.
