Area Code 1374 – Mori, Hokkaido

Overview of Area Code 1374

Area code 1374 is a geographic National Destination Code (NDC) within the Japanese numbering plan, assigned to the city of Mori in the Oshima Subprefecture of Hokkaido, Japan. This code is part of the broader +81 1374 numbering block, which serves the region surrounding Mori, including the towns of Shikabe and Sawara. The area is known for its scenic coastal location along the Tsugaru Strait and its role as a gateway to the Oshima Peninsula.

Geographic Coverage and Administrative Jurisdiction

The 1374 area code covers the administrative jurisdiction of Mori City and its surrounding municipalities within Hokkaido Prefecture. Specifically, it encompasses the urban center of Mori, the port area, and nearby rural communities. The region is part of the Hokkaido Regional Development Bureau's jurisdiction, and telecommunication services are provided by NTT East, which manages the fixed-line infrastructure for the area.

Dialing Formats and Instructions

For local callers within the Mori area code region, the standard local dialing format is a 6-digit subscriber number, which is dialed without the area code. For example, to call a local number, one would dial XXXXXX (where XXXXXX represents the 6-digit local number). However, when calling from outside the 1374 area code but still within Japan, callers must dial the trunk prefix 0, followed by the area code and the subscriber number: 0-1374-XXXXXX. For international callers, the format is +81-1374-XXXXXX, where the leading '0' is omitted. For instance, a call from the United States to a Mori number would be dialed as 011 81 1374 XXXXXX.

Numbering and Overlay Considerations

The 1374 area code is a geographic code with a subscriber number length of 6 digits, resulting in a total national significant number length of 10 digits (including the leading '0' when dialed domestically). There are no overlay codes currently in effect for this area, meaning that the 1374 code is exclusively used for fixed-line services in the Mori region. Mobile numbers in Japan use separate prefixes (e.g., 080, 090) and are not affected by this geographic code.

Caller Instructions

For local callers within the 1374 area, simply dial the 6-digit subscriber number. For callers from other parts of Japan, dial 0-1374-XXXXXX. For international callers, dial your country's exit code, then 81 (Japan's country code), then 1374, followed by the 6-digit local number. For example, from the UK, you would dial 00 81 1374 XXXXXX. It is important to note that when dialing from a mobile phone in Japan, the same domestic format applies, but the call will be charged as a domestic long-distance call if outside the local area.
