Area Code 1465 – Shizunai, Hokkaido

Overview of Area Code 1465

Area code 1465 is a geographic numbering plan area within the Japanese telephone numbering plan, specifically assigned to the Shizunai region in the Hidaka Subprefecture of Hokkaido. This code corresponds to the former town of Shizunai, now part of the city of Shinhidaka, which was formed in 2006 through the merger of Shizunai and Mitsuishi towns. The area code serves the administrative and commercial center of Shinhidaka, including the port area and surrounding districts, and is administered under the Ministry of Internal Affairs and Communications (MIC) of Japan.

Geographic Coverage and Dialing Formats

The 1465 area code covers the eastern part of the Hidaka region, with Shizunai as the principal city. It is bordered by the Pacific Ocean to the south and the Hidaka Mountains to the north. The region is known for its agriculture, forestry, and fishing industries, as well as its scenic coastline.

For local callers within the same area code (1465), the number is dialed as an 8-digit local number: XXXX XXXX. For example, a local call to a business in Shizunai would be dialed as 22 1234 (if the subscriber number is 22-1234). However, if you are calling from outside the 1465 area code but still within Japan, you must dial the trunk prefix 0 followed by the area code and the subscriber number: 0 1465 2 1234 (where the first digit of the subscriber number is typically 2 for landlines).

For international callers, the format is: +81 1465 2 1234. The leading zero of the area code is omitted when dialing from abroad. The plus sign (+) represents the international access code from your country (e.g., 011 from the US, 00 from most European countries).

Numbering Structure and Overlay Considerations

Japanese geographic numbers are structured as: Country Code (+81) + National Destination Code (NDC) + Subscriber Number. In this case, the NDC is 1465, and the subscriber number is 7 digits long, making the total national significant number (NSN) 10 digits when the leading 0 is included. There are no overlay codes in this region; the 1465 area code is unique to Shizunai and its vicinity. However, adjacent areas use different codes, such as 1464 for Mitsuishi (now part of Shinhidaka) and 1456 for Urakawa.

Caller Instructions

• Local callers (within 1465): Dial the 7-digit subscriber number without the area code.
• Domestic callers from other areas in Japan: Dial 0 1465 followed by the subscriber number.
• International callers: Dial your country's exit code, then 81 1465, then the subscriber number (omit the leading 0).

When calling from a mobile phone in Japan, it is common to include the area code even for local calls, as mobile numbers are non-geographic. Always verify the number with the recipient if you are unsure about the correct dialing format.
