Area Code 2964 – Shimodate, Ibaraki

Overview of Area Code 2964

Area code 2964 is a geographic National Destination Code (NDC) within the Japanese numbering plan, assigned to the city of Shimodate in Ibaraki Prefecture. This code forms part of the larger numbering area that covers the western region of Ibaraki, an area known for its agricultural production and historical significance. The city of Shimodate, now part of Chikusei City following municipal mergers, is served by this code, along with surrounding towns and villages.

Geographic Coverage and Administrative Jurisdiction

The 2964 area code encompasses Shimodate and its neighboring communities, including portions of the former districts of Makabe and Kawachi. Administratively, this region falls under the jurisdiction of Ibaraki Prefecture, which is located in the Kanto region of Honshu, Japan's main island. The area is well-connected by rail and road, with the JR Mito Line and the Kita-Kanto Expressway providing access to major urban centers like Tokyo and Mito.

Dialing Formats and Caller Instructions

For local callers within the same numbering area (i.e., dialing from another number with the 2964 area code), the national significant number is typically 6 digits, and calls can be made by dialing the subscriber number directly without the area code. However, for calls originating from outside the 2964 area but within Japan, the full national format must be used: 0-2964-XXXXXX. International callers should dial +81-2964-XXXXXX, omitting the leading zero of the trunk prefix.

For example, to call a number in Shimodate from abroad, you would dial +81 2964 123456. If you are calling from a mobile phone in Japan, you must include the area code even if you are in the same region, as mobile numbers are not geographically tied.

Overlay and Numbering Considerations

As of the latest ITU-T E.164 allocation, there is no overlay code for the 2964 area, meaning that the 0-2964 prefix is unique to this geographic region. The number length for local subscribers is 6 digits, making the total national significant number 10 digits (including the area code). This structure is consistent with Japan's closed numbering plan, where the trunk prefix '0' is used for domestic calls.

Practical Information for Callers

When placing international calls to Shimodate, ensure you have the correct country code (+81) and drop the initial '0' of the area code. For domestic long-distance calls, always include the '0' before the area code. For example, from Tokyo, you would dial 0-2964-XXXXXX. It is also important to note that some VoIP services may require a different dialing format; always check with your service provider for specific instructions.
