Area Code 1372 – Shikabe, Hokkaido

Overview of Area Code 1372

Area code 1372 is a geographic National Destination Code (NDC) assigned to the town of Shikabe (鹿部町), located in the Oshima Subprefecture of Hokkaido, Japan. This code is part of the Japanese numbering plan administered by the Ministry of Internal Affairs and Communications (MIC) and the Telecommunications Carriers Association (TCA). The region is served by landline PSTN and VoIP services, with numbers typically formatted as 01372-X-XXXX or 01372-XX-XXXX, depending on the subscriber line capacity.

Geographic Coverage and Jurisdiction

Shikabe is a small coastal town situated on the southeastern shore of Lake Onuma, within the greater Hakodate metropolitan area. The 1372 area code covers the administrative boundaries of Shikabe town, including the central districts of Shikabe, Minato, and the surrounding rural areas. The code is also used for some nearby communities that rely on the Shikabe telephone exchange. The region is part of the Hokkaido prefecture, known for its scenic hot springs and fishing industry.

Dialing Formats

For local callers within the 1372 area code, the national trunk prefix '0' is used, followed by the area code and the subscriber number. For example, to call a local number, one would dial: 01372-X-XXXX. For callers from other parts of Japan, the same format applies: 01372-X-XXXX. International callers from outside Japan must use the country code +81, drop the leading '0', and dial: +81 1372-X-XXXX. For instance, a typical international dialing sequence would be +81 1372 3 4567.

Overlay and Numbering Considerations

As of the latest MIC data, no overlay area code has been introduced for the 1372 region. The area code remains a standalone NDC, and the subscriber numbers are typically 4 to 5 digits long, making the total national significant number (NSN) length 9 or 10 digits (including the leading '0'). This is consistent with the Japanese numbering plan, which allows variable NSN lengths depending on the area code and subscriber capacity.

Caller Instructions

For local callers within Shikabe, it is essential to include the area code even for local calls, as Japan does not use local dialing without the trunk prefix in most geographic areas. For callers from other regions in Japan, simply dial the 10-digit number starting with '0'. For international callers, remember to replace the leading '0' with the country code +81. This ensures proper routing through the international gateway.

Technical Notes

Geographic numbers in Japan are assigned to fixed-line services, but they can also be used by VoIP providers that offer fixed-line equivalents. Number portability allows subscribers to retain their numbers when switching between fixed-line carriers, but the geographic significance remains tied to the original exchange location. For businesses, having a 1372 number establishes a local presence in Shikabe, which can be beneficial for customer trust and regional marketing.
