Area Code 9976 – Naze, Kagoshima

Overview of Area Code 9976 (Naze, Kagoshima)

Area code 9976 is a geographic National Destination Code (NDC) within the Japanese numbering plan, assigned to the Naze region in Kagoshima Prefecture. Naze is the principal city on Amami Ōshima, the largest island in the Amami archipelago, which is part of the Satsunan Islands. The code serves the city of Amami (formerly Naze) and its surrounding administrative districts, including the towns of Tatsugō, Yamato, and Uken, as well as the island of Kakeroma-jima. This area is known for its subtropical climate, coral reefs, and unique cultural heritage.

Under the ITU-T E.164 standard, the full international dialing format for a subscriber number in this region is +81 9976 X-XXXX, where +81 is the country calling code for Japan, 9976 is the area code, and the subscriber number is seven digits long. In domestic dialing, the area code is preceded by the trunk prefix 0, resulting in 0 9976 X-XXXX when calling from elsewhere in Japan. Local calls within the same area code may be made using only the seven-digit subscriber number, without the area code, depending on the specific local dialing plan.

Dialing Instructions

• From within Japan (outside the 9976 area): Dial 0 9976 X-XXXX. For example, to call a Naze number 123-4567, dial 09976-123-4567.
• From abroad: Dial your country's international access code (e.g., 011 in the US, 00 in many countries), then 81 9976 X-XXXX. For instance, from the UK, dial 00 81 9976 123 4567.
• Local calls within the Naze area: Often, only the seven-digit number is required, but confirm with your local service provider as some areas require the full national number.

Geographic and Administrative Context

The Naze area code is part of the Kagoshima prefectural numbering region, which is subdivided into several area codes. The region is served by Nippon Telegraph and Telephone (NTT) and other licensed carriers, providing PSTN and VoIP services. As of the latest numbering plan updates, no overlay codes have been introduced for this area, meaning the 9976 code remains the sole geographic code for the region.

For international callers, it is essential to note that Japanese numbers are not portable across geographic areas; the code strictly indicates the physical location of the line. However, with the rise of VoIP and IP telephony, some numbers may be used outside the region, but the code retains its geographic significance for routing and regulatory purposes.

When dialing from a mobile phone in Japan, the same national format applies, and callers should include the area code even when dialing a local number, as mobile networks do not automatically add the area code. For international SMS or calls to this region, the standard +81 9976 format is used.
