Area Code 482 – Sinjai

Overview of Area Code 482 (Sinjai, Indonesia)

Area code 482 is a geographic National Destination Code (NDC) assigned to the Sinjai Regency (Kabupaten Sinjai) in the province of South Sulawesi (Sulawesi Selatan), Indonesia. This code is part of the Indonesian national numbering plan, which adheres to ITU-T E.164 recommendations. The region is located on the southwestern coast of Sulawesi Island, approximately 220 kilometers from Makassar, the provincial capital. Sinjai is known for its agricultural production, coastal fisheries, and scenic highlands.

Geographic area codes in Indonesia are used for fixed-line (PSTN) services, and 482 is specifically allocated to the Sinjai exchange area. Subscribers within this code are typically served by local telecommunications providers, including Telkom Indonesia and other licensed operators. The code covers the administrative districts of Sinjai, including the capital Sinjai Town (Sinjai Utara) and surrounding areas such as Sinjai Selatan, Sinjai Timur, and Sinjai Barat.

Dialing Formats

When calling a fixed-line number in Sinjai, the dialing format depends on the caller's location:

• Local calls (within Sinjai): Dial only the subscriber number, which typically consists of 5 to 7 digits. For example, if the subscriber number is 12345, dial 12345.
• National calls (from other parts of Indonesia): Dial the trunk prefix 0, followed by the area code 482, and then the subscriber number. For instance, to reach a Sinjai number 12345 from Jakarta, dial 0-482-12345.
• International calls (from outside Indonesia): Dial the international access prefix (e.g., 00 or +), followed by Indonesia's country code 62, then the area code without the leading zero, and the subscriber number. For example, from the United States, dial 011-62-482-12345 or +62-482-12345.

It is important to note that the area code 482 is not used for mobile numbers. Mobile numbers in Indonesia begin with 8 (e.g., 0811, 0812, 0852) and are non-geographic. If you receive a call from a number starting with +62 482, it is a fixed-line call from Sinjai.

Overlay and Numbering Changes

As of the latest ITU-T and national regulatory updates, there is no overlay code for Sinjai. The area code 482 remains the sole geographic code for the region. However, with the ongoing migration to all-IP networks, some fixed-line services may be delivered over VoIP, but the geographic numbering plan is preserved for number portability and regulatory reasons. Callers should always verify the correct number with the recipient, especially when calling from mobile networks, as some operators may require the full national number including the trunk prefix.

For international callers, it is essential to drop the leading zero of the area code when dialing from abroad. The Indonesian country code is +62, and the area code 482 is used without the zero. This standard international format ensures proper routing through the global PSTN.

In summary, area code 482 is a vital part of Indonesia's telecommunications infrastructure, connecting Sinjai to the rest of the nation and the world. Whether you are placing a business call or contacting local services, understanding the correct dialing procedures will ensure seamless communication.
