Area Code 1332 – Tobetsu, Hokkaido

Overview of Area Code 1332

Area code 1332 is a geographic National Destination Code (NDC) within the Japanese numbering plan, assigned to the town of Tobetsu in the Ishikari Subprefecture of Hokkaido. This code is part of the larger Sapporo metropolitan area numbering group, which uses the 011 prefix for central Sapporo but employs distinct codes for surrounding municipalities. The 1332 code specifically serves Tobetsu-cho and its immediate environs, including the communities of Uryu and parts of the Ishikari plain. The region is known for its agricultural production, particularly rice and vegetables, and is situated along the Ishikari River.

Geographic Coverage and Administration

Tobetsu is administered under Hokkaido Prefecture and falls within the jurisdiction of the Ishikari Subprefecture. The area code 1332 is allocated to the Tobetsu exchange area, which encompasses the town center and several rural districts. It is important to note that while Tobetsu is geographically close to Sapporo, it does not use the 011 code; instead, it maintains its own distinct NDC. This distinction is crucial for call routing and billing purposes.

Dialing Formats

For local callers within the Tobetsu area, the number is dialed as 01332-X-XXXX, where X-XXXX represents the subscriber number. However, when calling from outside the 1332 area but still within Japan, the trunk prefix 0 must be included, followed by the area code and subscriber number: 01332-X-XXXX. For international callers, the format is +81 1332-X-XXXX, omitting the leading zero. For example, a typical Tobetsu number might be 01332-5-1234 domestically, or +81 1332-5-1234 from abroad.

Overlay and Numbering Considerations

Currently, there is no overlay code for the 1332 area. Subscriber numbers in this area typically have a total length of 10 digits when including the area code (excluding the trunk prefix). The numbering plan follows the Japanese Ministry of Internal Affairs and Communications (MIC) guidelines, ensuring that all geographic numbers are portable within the same area code. However, number portability does not allow moving a geographic number to a different area code without changing the number.

Caller Instructions

For callers within Japan, if you are dialing from a mobile phone, you may need to include the area code even if you are in the same region, depending on your carrier. Always use the full 10-digit number (including the leading 0) for domestic calls. For international callers, replace the leading 0 with the country code +81 and drop the 0. Ensure you have the correct country code and area code to avoid misdialing.
