Area Code 1535 – Akkeshi, Hokkaido

Overview of Area Code 1535

Area code 1535 is a geographic National Destination Code (NDC) within the Japanese numbering plan, assigned to the town of Akkeshi in the Kushiro Subprefecture of Hokkaido Prefecture. This code serves the administrative and residential districts of Akkeshi, including the central town area and surrounding rural communities. The region is known for its coastal location along the Pacific Ocean and its oyster farming industry.

Geographic Coverage and Jurisdiction

The 1535 area code covers the entirety of Akkeshi Town, which falls under the jurisdiction of the Kushiro General Subprefectural Bureau. The town is situated in eastern Hokkaido, approximately 60 kilometers east of the city of Kushiro. The area code is used for fixed-line telephone services, including PSTN and IP-based fixed telephony, and is administered by Nippon Telegraph and Telephone (NTT) East under the Ministry of Internal Affairs and Communications (MIC) regulations.

Dialing Formats and Instructions

When calling a fixed-line number in Akkeshi from within Japan, you must dial the trunk prefix 0, followed by the area code 1535, and then the subscriber number. Local numbers in this area typically consist of five digits, making the complete national significant number (NSN) ten digits long (including the leading zero). For example, a local number might be 1535-2-XXXX (where XXXX is the subscriber's line).

For international callers, the Japanese country code +81 replaces the trunk prefix. Therefore, to call the same number from abroad, you would dial +81 1535 2 XXXX. Note that the leading zero is omitted when using the international format.

Overlay and Numbering Considerations

As of the latest numbering plan updates, there is no overlay code for the 1535 area. The area code remains exclusive to Akkeshi, and no changes have been announced. However, users should be aware that number portability (fixed-line number portability) is available in Japan, allowing subscribers to retain their numbers when switching carriers, though the geographic significance of the code remains unchanged.

Practical Guidance for Callers

• Local callers within Akkeshi can often dial the subscriber number without the area code, depending on their service provider's local calling area definitions. However, for clarity and to avoid misdialing, it is recommended to always include the area code when calling from a different area.
• Domestic callers from other parts of Japan must dial 0-1535-XXXXX (where XXXXX is the five-digit subscriber number).
• International callers should dial +81 1535 XXXXX, omitting the leading zero of the area code.

For emergency services, dial 110 (police) or 119 (fire/ambulance) from any phone, regardless of the area code.
