Area Code 1455 – Mukawa, Hokkaido

Overview of Area Code 1455

Area code 1455 is a geographic National Destination Code (NDC) assigned to the town of Mukawa, located in the Yufutsu Subprefecture of Hokkaido, Japan. This code is part of the Japanese telephone numbering plan, which adheres to the ITU-T E.164 standard. The region served by 1455 is primarily rural and coastal, with Mukawa being the central administrative and commercial hub. The area is known for its fishing industry and scenic landscapes.

Geographic Coverage and Administrative Jurisdiction

The 1455 area code covers the municipality of Mukawa and its surrounding districts. Mukawa is situated on the Pacific coast of Hokkaido, approximately 80 kilometers east of Sapporo, the prefectural capital. The jurisdiction falls under the Hokkaido Prefectural Government, and the local telephone services are provided by NTT East, the regional incumbent carrier. The numbering area is classified as geographic, meaning that the code is tied to a specific physical location.

Dialing Formats and Instructions

For local callers within the 1455 area, the dialing format is the 7-digit subscriber number alone. For example, if the subscriber number is 123-4567, a local call would simply dial 1234567. However, for callers from outside the area but within Japan, the full national format must be used: 0-1455-123-4567. The leading '0' is the trunk prefix used for domestic calls. For international callers, the format is +81-1455-123-4567, where '+81' is the country code for Japan, and the leading '0' is omitted. It is important to note that the area code 1455 is not an overlay; it is the sole code for this region, and no other codes share the same geographic area.

Caller Instructions

When calling from overseas, you must replace the '0' with the international access code of your country, then dial 81 (Japan's country code), followed by 1455 and the subscriber number. For example, to reach a number in Mukawa from the United States, you would dial 011-81-1455-123-4567. If you are calling from a mobile phone in Japan, you can dial the number in the same format as a landline, but be aware that charges may apply depending on your carrier plan. For emergency services, always dial 110 (police) or 119 (fire/ambulance) regardless of the area code.

Numbering and Routing Considerations

Subscriber numbers within the 1455 area code are 7 digits long, and the total number length for a domestic call is 10 digits (including the trunk prefix '0'). The Japanese Numbering Plan ensures that all geographic area codes are unique, and routing is based on the NDC. There are no special routing considerations for this area, but as with all geographic codes, number portability is available for fixed-line services, allowing subscribers to retain their numbers when switching carriers within the same geographic area.
