Area Code 901 – Timika

Overview of Area Code 901 (Timika, Indonesia)

Area code 901 is a geographic National Destination Code (NDC) assigned to the city of Timika and its surrounding regency (Kabupaten Mimika) in the province of Central Papua, Indonesia. This code is part of the Indonesian public switched telephone network (PSTN) numbering plan, administered under the ITU-T E.164 recommendation. Timika serves as a major administrative and commercial hub for the region, largely due to the presence of the Grasberg mine, one of the world's largest gold and copper mines. The area code covers the urban center of Timika as well as several districts within the Mimika Regency, including Kwamki Narama, Mimika Baru, and Wania. For callers within Indonesia, the trunk prefix 0 is used before the area code, resulting in the domestic dialing format 0-901-XXX-XXXX. For international callers, the country code for Indonesia is +62, and the leading trunk prefix is dropped, yielding the international dialing format +62-901-XXX-XXXX.

Dialing Instructions

To place a call to a fixed-line number in Timika, the following procedures apply:

• Local calls within Timika: If you are dialing from another number within the same area code, you may typically dial only the local subscriber number. However, due to varying local exchange configurations, it is always safe to dial the full national number: 0901 XXX XXXX.
• National long-distance calls (from other Indonesian cities): Dial the trunk prefix 0, then the area code 901, followed by the 7- to 8-digit subscriber number. Example: 0901 123 4567.
• International calls to Timika: Dial your country's international exit code (e.g., 00 from many countries, or 011 from the US/Canada), then Indonesia's country code 62, then the area code 901 (without the leading 0), followed by the subscriber number. Example: +62 901 123 4567.

Numbering and Overlay Considerations

As of the latest ITU-T national numbering plan updates, area code 901 is a geographic code without any overlay codes. Subscriber numbers within this area typically consist of 7 to 8 digits, but the total length of a national significant number (NSN) is usually 9 to 10 digits (including the area code). The Indonesian Telecommunication Regulatory Authority (BRTI) manages the allocation of number blocks to local fixed-line operators, such as Telkom Indonesia and other regional providers. No major overlay or migration is currently scheduled, but users should always verify the current dialing procedures with their service provider, especially when making calls from mobile networks, as some operators may require the full national number even for local calls.

Geographic and Economic Context

Timika is located on the southern coast of Papua, near the Arafura Sea, and serves as the primary gateway to the highland mining areas. The region has a significant expatriate and corporate presence due to mining operations, leading to a demand for reliable communication services. The fixed-line infrastructure in Timika is complemented by mobile and satellite services, but area code 901 remains essential for reaching businesses, government offices, and residential landlines in the area. For enterprises establishing a presence in Timika, obtaining a local geographic number with the 901 code can enhance local trust and accessibility.
