Area Code 2474 – Ishikawa, Fukushima

Overview of Area Code 2474

Area code 2474 is a geographic numbering plan area within the Japanese telephone numbering system, conforming to the ITU-T E.164 standard. It is part of the national destination code (NDC) structure for Japan, which is prefixed by the country calling code +81. The 2474 area code is assigned to a specific region in the Ishikawa Prefecture, located on the west coast of Honshu, Japan's main island. Specifically, it serves the city of Nanao and its surrounding areas, including the Noto Peninsula. This region is known for its scenic coastal landscapes, traditional crafts, and historical sites. The administrative jurisdiction falls under the Ishikawa Prefectural Government, and the primary cities served include Nanao, Himi (though Himi is in Toyama Prefecture, it is part of the same dialing area), and the towns of Nakajima and Noto. The area code 2474 is used for fixed-line telephone services, including PSTN and VoIP services that are geographically tied to the region.

Dialing Formats

When dialing a number within the 2474 area code from another location within Japan, the trunk prefix 0 is used, followed by the area code and the subscriber number. For example, to call a landline in Nanao from Tokyo, one would dial: 0 2474 5X XXXX (where X represents the subscriber digits). Internationally, callers from outside Japan must replace the leading 0 with the country code +81, resulting in the format: +81 2474 5X XXXX. It is important to note that the area code is not separated by a space when dialing internationally; the plus sign and country code are followed directly by the area code (without the leading zero) and the subscriber number. Local calls within the same area code may be made using just the subscriber number, but for clarity and to avoid misdialing, it is recommended to include the area code even for local calls.

Geographic Coverage and Overlays

The 2474 area code covers a geographically defined region, and there are no overlay codes currently assigned to this area. This means that the area code is not shared with other codes for the same geographic region, and the number length is fixed: the total number of digits for a complete international number is 13, including the country code. The numbering plan is managed by the Ministry of Internal Affairs and Communications (MIC) in Japan, and number allocation is administered by the Telecommunications Carriers Association. For callers within Japan, the area code is an essential part of the national dialing plan, and for international callers, it is crucial to use the correct country code and area code to reach the desired party.

Caller Instructions

For local callers within the 2474 area code, dialing the full national number (including the area code) is always safe, even for calls to the same city. For callers from other regions in Japan, the national format is used: 0-2474-XXXXXX. For international callers, the format is +81-2474-XXXXXX. It is also important to note that some numbers in this area may be used for mobile services, but the 2474 code is primarily for fixed-line services. When calling from abroad, ensure that you have the correct international exit code for your country (e.g., 011 from the US, 00 from most European countries) before dialing +81. This will ensure proper routing through the international PSTN.
