Area Code 2475 – Ishikawa, Fukushima

Overview of Area Code 2475

Area code 2475 is a geographic National Destination Code (NDC) within the Japanese numbering plan, assigned under the international country calling code +81. It serves the city of Ishikawa in Fukushima Prefecture, located in the Tōhoku region of Honshu, Japan. This code is part of the historic 0247 numbering area, which was subdivided to accommodate growing demand for telecommunication services in the region.

Geographic Coverage and Administrative Jurisdiction

The 2475 area code covers the city of Ishikawa and its surrounding administrative districts, including former towns and villages that have been integrated into the greater Ishikawa municipal area. The region is known for its scenic landscapes, agricultural production, and traditional crafts. Key localities served by this code include central Ishikawa, as well as neighboring communities within the Ishikawa city limits.

Dialing Formats and Caller Instructions

For callers within Japan, the domestic dialing format for numbers in the 2475 area code is 02475-X-XXXX, where 02475 is the full national significant number prefix (including the trunk prefix 0). The total subscriber number length after the area code is typically 6 digits, making the complete national number 10 digits (excluding the initial 0).

For international callers, the correct format is +81 2475 X-XXXX, where the leading zero is dropped. For example, a local number such as 02475-1-2345 would be dialed as +81 2475 12345 from overseas.

When calling from a mobile phone within Japan, the same domestic format (02475-X-XXXX) is used. However, if you are dialing from a foreign country, ensure you use the international access code of your country (e.g., 011 from the US, 00 from most European countries) followed by 81 and the area code without the leading zero.

Overlay and Numbering Considerations

As of the latest ITU-T and Ministry of Internal Affairs and Communications (MIC) updates, area code 2475 is not part of an overlay complex; it is a standalone geographic code. However, number portability is available in Japan, allowing subscribers to retain their numbers when switching between fixed-line operators, provided they remain within the same geographic area. This does not affect the area code itself.

Practical Usage and Tips

For businesses and residents in Ishikawa, using the correct area code is essential for successful call routing. When dialing from a landline in a different area code within Japan, you must include the trunk prefix 0 and the area code. For example, a caller from Tokyo (03) would dial 02475-X-XXXX. For callers from overseas, the plus sign (+) is recommended to ensure proper international routing.

Always verify the number length and format with your service provider or the recipient, as local numbers may have varying lengths. For further assistance, consult the official MIC numbering plan or your telecom operator.
