Area Code 2967 – Kasama, Ibaraki

Geographic Coverage and Administrative Jurisdiction

The area code 2967 is a geographic National Destination Code (NDC) assigned to the city of Kasama, located in Ibaraki Prefecture, Japan. This code is part of the Japanese numbering plan under ITU-T E.164, where the country calling code +81 is followed by the NDC and the subscriber number. Kasama is a city in the central part of Ibaraki Prefecture, known for its historical shrines and pottery. The administrative jurisdiction covers the city limits of Kasama, including its central urban area and surrounding districts. The code is used for fixed-line (PSTN) services, including traditional analog lines, ISDN, and some VoIP services that are assigned geographic numbers.

Dialing Formats and Caller Instructions

For local callers within Japan, the number is dialed as 02967 followed by the local subscriber number. The full national dialing format is 02967-XX-XXXX (where X represents the subscriber digits). When calling from outside Japan, the international format is +81 2967 XX XXXX, with the leading zero of the NDC omitted. For example, a typical Kasama number might be +81 2967 12 3456. Local callers within the same NDC area can often dial the subscriber number directly without the area code, but this depends on the specific carrier and whether overlay plans are in effect. As of now, no overlay codes have been introduced for this area, so the 02967 code remains the sole geographic code for Kasama.

Technical Considerations and Numbering

The subscriber numbers associated with this code typically consist of 4 to 6 digits, making the total national significant number (NSN) length 10 digits when including the NDC. The code is allocated to Nippon Telegraph and Telephone (NTT) East, the incumbent local exchange carrier, but other carriers may offer services using this code through interconnection. Number portability is available for fixed-line services in Japan, allowing subscribers to retain their numbers when switching carriers within the same geographic area. For VoIP services that use geographic numbers, the same dialing rules apply, but the service may be accessed via an IP network. Callers from mobile phones in Japan must dial the full national number, including the area code, as mobile networks do not support local dialing without the area code.

Practical Guidance for Callers

When calling a Kasama number from abroad, always replace the leading zero with the country code +81. For example, to call a number listed as 02967-12-3456, international callers should dial +81 2967 12 3456. Ensure that you have the correct number of digits after the area code, as subscriber numbers can vary in length. If you are unsure about the number, consult a directory or contact your service provider. For businesses, it is important to note that calls to geographic numbers are typically charged at standard domestic rates, which may vary depending on the carrier and the caller's plan.
