Area Code 1525 (Japan) - Prefix Details & Exchanges

Geographic Overview

The area code 01525 is a geographic National Destination Code (NDC) assigned to the Abashiri region in northeastern Hokkaido, Japan. This code serves the city of Abashiri and its surrounding administrative areas, including the towns of Bihoro, Tsubetsu, and parts of Koshimizu. Abashiri is known for its coastal location on the Sea of Okhotsk and its role as a regional economic and transport hub.

Dialing Formats

For local callers within the Abashiri area, the number is dialed as 01525-X-XXXX, where X-XXXX is the subscriber number. When calling from other regions in Japan, the full national format is 01525-X-XXXX (including the leading 0). International callers should dial +81 1525-X-XXXX, omitting the leading zero of the NDC.

Jurisdictional and Administrative Details

The Abashiri code is managed under the Japanese Ministry of Internal Affairs and Communications (MIC) numbering plan, which follows ITU-T E.164 recommendations. The area is part of the Hokkaido prefecture, and the code is classified as a geographic allocation, meaning that the number is tied to a specific physical location and is typically used for fixed-line PSTN services. However, with the advent of number portability, some subscribers may have migrated to VoIP or other technologies while retaining their geographic number.

Overlay and Numbering Considerations

As of the latest updates, there is no overlay code for the Abashiri area, and the 01525 code remains the sole geographic code for this region. The subscriber number length is typically 6 digits, resulting in a total national significant number (NSN) length of 10 digits (including the leading 0). This is consistent with the standard Japanese numbering plan.

Caller Instructions

Local callers within the Abashiri area can dial the 6-digit subscriber number directly without the area code in some cases, but it is recommended to use the full 10-digit format to avoid confusion, especially with mobile numbers.
Callers from other parts of Japan must dial 01525 followed by the subscriber number.
International callers should dial the Japanese country code +81, then 1525 (without the leading 0), followed by the subscriber number.

Example

For a subscriber number 123456, the local dialing format is 01525-123456, and the international format is +81 1525-123456.
