Area Code 1562 – Honbetsu, Hokkaido

Overview of Area Code 1562

Area code 1562 is a geographic numbering plan area within the Japanese telecommunications network, specifically allocated to the town of Honbetsu in the Tokachi Subprefecture of Hokkaido. This code is part of the national destination code (NDC) structure defined under ITU-T E.164, and it is used for fixed-line (PSTN) services. The area code covers Honbetsu and its immediate surroundings, including parts of the Tokachi Plain, a region known for agriculture and dairy farming.

Geographic Coverage and Administrative Jurisdiction

Honbetsu is a town located in the central part of Hokkaido, Japan's northernmost island. The area code 1562 serves the town's administrative boundaries, which include the central urban area and several rural districts. The region is governed by the Tokachi Subprefectural Office, based in Obihiro, which is the largest city in the area. While Obihiro itself uses a different area code (0155), Honbetsu and its neighboring villages rely on 1562 for their fixed-line telephone services.

Dialing Formats and Caller Instructions

For callers within Japan, dialing a number in Honbetsu requires the format: 01562-X-XXXX, where the leading '0' is the trunk prefix, '1562' is the area code, and the subscriber number typically consists of 5 to 6 digits. For example, a local number might be 01562-3-4567. When calling from outside Japan, the international format is +81 1562-X-XXXX, omitting the leading '0'. For instance, an international caller would dial +81 1562-3-4567.

It is important to note that Japan's numbering plan does not use a separate trunk prefix for domestic calls; the '0' is part of the national significant number. When dialing from a mobile phone within Japan, the same format applies, but if the caller is outside the area code, they must include the area code. For calls from abroad, the plus sign (+) indicates the international access code, which varies by country (e.g., '011' from the US, '00' from most European countries).

Overlay and Numbering Considerations

As of the latest ITU-T allocations, there is no overlay code for the 1562 area. The area code is exclusive to Honbetsu and does not share numbering resources with adjacent areas. However, with the ongoing transition to IP-based networks, some fixed-line numbers may be assigned to VoIP services, but the geographic association remains for emergency services and number portability. Callers should always verify the correct area code, as misdialing can route calls to other parts of Hokkaido.

Practical Usage

For businesses or individuals in Honbetsu, the area code is essential for local communications. When listing a phone number internationally, it is standard to write it as +81 1562-XX-XXXX. For travelers, using a local SIM or a roaming service, dialing a Honbetsu number requires the same international format. The area code is also used for fax lines and other fixed-line services, maintaining the reliability expected from Japan's PSTN.
