Geographic Overview
The +62 389 country calling code and area code combination routes calls to the geographic region of Atambua, the administrative capital of the Belu Regency in East Nusa Tenggara (Nusa Tenggara Timur) province, Indonesia. Atambua is located on the island of Timor, near the border with Timor-Leste (East Timor). The code 389 is a National Destination Code (NDC) assigned to the PSTN (Public Switched Telephone Network) infrastructure serving this area. It covers the urban center of Atambua and its surrounding districts, including the sub-districts of Atambua Kota, Atambua Barat, and Atambua Selatan, as well as nearby towns such as Kefamenanu (in North Central Timor Regency) and Betun (in Malaka Regency) that may share the same trunk numbering area.
Dialing Formats
For callers within Indonesia, the trunk prefix '0' is used before the area code. The national format is: 0 389 XXX XXXX (where X represents the local subscriber number). For example, a local number might be dialed as 0389 123 4567.
For international callers, the country code +62 is used, followed by the area code without the leading '0'. The international format is: +62 389 XXX XXXX. Thus, the same number would be dialed as +62 389 123 4567 from outside Indonesia.
Caller Instructions
- Local callers within Atambua: If you are calling within the same area code, you may often omit the area code and dial only the local subscriber number (XXXX XXXX). However, for clarity and to avoid misdialing, it is recommended to use the full national format.
- Callers from other Indonesian cities: Dial 0 389 XXX XXXX.
- International callers: Dial your country's international access code (e.g., 00 from many countries, or +), then 62 389 XXX XXXX.
Regulatory and Technical Notes
As a geographic code, 389 is allocated by the Indonesian Telecommunication Regulatory Authority (BRTI) to fixed-line operators providing services in the region. The code is not portable across geographic areas; it is tied to the physical location of the line. Overlay codes have not been introduced for this area, so the 389 code is the sole geographic code for Atambua. The numbering plan follows ITU-T E.164 recommendations, with a maximum length of 15 digits for international numbers.
When calling from a mobile phone, the same dialing rules apply. Ensure you include the area code even when dialing from a mobile device, as mobile numbers are non-geographic and require the full national number.
