Area Code 911 – Ambon

Geographic Overview: Ambon and the 911 Area Code

The +62 911 country and area code combination is the international dialing prefix for the island of Ambon, the capital of Maluku Province in eastern Indonesia. Ambon is the primary city within the Ambon Island municipality (Kota Ambon) and serves as the economic, administrative, and cultural hub of the Maluku Islands. The geographic coverage of the 911 code extends across the island, including the main urban districts of Nusaniwe, Sirimau, Teluk Ambon, and Baguala, as well as surrounding coastal settlements. As part of Indonesia's national numbering plan, the 911 prefix is classified as a Geographic Area Code, meaning it is allocated specifically to fixed-line telephone services within this defined region.

Dialing Formats and Caller Instructions

For callers dialing from within Indonesia (outside the Ambon area), the domestic trunk prefix '0' is used followed by the area code and the subscriber number. The local subscriber number in Ambon typically consists of 5 to 7 digits, depending on the exchange and service provider. The complete national dialing format is: 0 911 XXX XXXX (where 'X' represents the local number). For example, a local number such as 1234567 would be dialed as 0911 1234567 from other parts of Indonesia.

International callers must replace the leading '0' with Indonesia's country code +62, omitting the trunk prefix. The international format becomes: +62 911 XXX XXXX. For instance, the same number would be dialed as +62 911 1234567 from abroad. It is crucial to note that the area code '911' is not related to emergency services; in Indonesia, the universal emergency numbers are 112 (general emergency) and 110 (police).

Overlay and Numbering Considerations

Currently, there is no overlay code for Ambon; the 911 code remains the sole geographic area code for the region. However, as with many Indonesian cities, the demand for fixed-line numbers has led to the introduction of additional digits in subscriber numbers over time. Callers should always verify the current number length with the called party or service provider. For VoIP and mobile users, the geographic nature of the code means that calls to 911 numbers are typically charged at domestic fixed-line rates when dialed from within Indonesia, while international rates apply from abroad. The code is managed under the jurisdiction of the Indonesian Telecommunication Regulatory Authority (BRTI), and all fixed-line operators serving Ambon, including Telkom Indonesia and other local carriers, utilize this code for their PSTN services.
