Area Code 1533 – Nemuro, Hokkaido

Overview of Area Code 1533

Area code 1533 is a geographic National Destination Code (NDC) within the Japanese numbering plan, assigned to the Nemuro region in eastern Hokkaido. It serves the city of Nemuro and its surrounding administrative districts, including the Nemuro Subprefecture. This code is used for fixed-line (PSTN) services, and it follows the ITU-T E.164 standard for international dialing.

Geographic Coverage and Administrative Jurisdiction

The 1533 area code covers the Nemuro region, which is the easternmost part of Hokkaido. Key locations include Nemuro City, the town of Rausu, and the villages of Shibetsu and Betsukai. The region is known for its proximity to the disputed Northern Territories (Kuril Islands) and its fishing industry. The administrative jurisdiction falls under the Nemuro Subprefectural Office, which oversees local services and telecommunications infrastructure.

Dialing Formats and Instructions

When calling a number in the Nemuro area from within Japan, you must dial the trunk prefix 0, followed by the area code 1533 and the subscriber number. Local numbers in this area are typically 6 digits long, making the complete national format: 0-1533-XXXXXX. For example, a local call to a business would be dialed as 01533-XXXXXX (the trunk prefix 0 is included).

For international callers, the dialing format is: +81-1533-XXXXXX, where +81 is the country code for Japan, and the leading 0 of the trunk prefix is omitted. For instance, a caller from the United States would dial 011-81-1533-XXXXXX, while a caller from the United Kingdom would dial 00-81-1533-XXXXXX.

Overlay and Numbering Considerations

Currently, there is no overlay code for the 1533 area; it remains a standalone geographic code. However, as with all Japanese fixed-line numbers, subscribers can retain their numbers when switching between different fixed-line carriers (carrier number portability). This means that even if a subscriber moves to a different operator, the 1533 prefix may not necessarily indicate the physical location of the exchange, though it generally corresponds to the Nemuro area.

Caller Instructions

Local callers within the 1533 area can dial the subscriber number directly without the area code, but this is not common practice in Japan; most calls use the full national format. Callers from other parts of Japan must dial 01533-XXXXXX. International callers must use the country code and drop the leading zero: +81-1533-XXXXXX.

It is important to note that calls to this geographic number are charged according to the distance-based tariff of the subscriber's carrier, though many carriers offer flat-rate plans for domestic calls. Emergency services (police, fire, ambulance) are reached via 110 and 119 respectively, regardless of the area code.
