Area Code 742 – Kualatungkal/Tebing Tinggi

Overview of Area Code 742

Area code 742 is a geographic National Destination Code (NDC) within the Indonesian numbering plan, assigned to the western coastal region of Jambi Province on the island of Sumatra. Specifically, it serves the administrative regency of Tanjung Jabung Barat and its principal town, Kualatungkal, along with the nearby town of Tebing Tinggi (not to be confused with the city of the same name in North Sumatra). The code covers the districts of Tungkal Ilir, Tungkal Ulu, and Betara, among others, facilitating PSTN and fixed-line services in this primarily agricultural and maritime area.

Dialing Formats and Usage

When calling a fixed-line subscriber in Kualatungkal or Tebing Tinggi from within Indonesia, you must include the trunk prefix 0 followed by the area code and the subscriber's 5- to 7-digit local number. The national format is: 0 742 XXXX XXX (where the total number of digits after the trunk prefix is typically 7 to 9). For example, a local number might be dialed as 0742 12345 or 0742 1234567 depending on the specific line.

For international callers, the country code for Indonesia is +62. You must drop the leading 0 and dial: +62 742 XXXX XXX. For instance, if the national number is 0742 123456, the international format becomes +62 742 123456. This format is essential for proper routing through international gateways.

Geographic and Administrative Context

Kualatungkal is the capital of Tanjung Jabung Barat Regency, located near the mouth of the Pengabuan River. The area is known for its palm oil plantations, fisheries, and emerging port activities. Tebing Tinggi, a separate town within the same regency, also falls under this code. The region is part of the larger Jambi Province, which borders the Strait of Malacca to the east.

As a geographic code, 742 is tied to specific physical exchanges and does not follow mobile numbers. Mobile services in Indonesia use separate non-geographic prefixes (e.g., 0811, 0822). If you are unsure whether a number is fixed or mobile, note that geographic codes like 742 are typically used for landlines, and the number length after the area code is shorter than mobile numbers.

Caller Instructions

• Local callers within the same area code can often dial the local number directly without the area code, but for clarity and to avoid misrouting, it is recommended to include the full national format.
• Domestic long-distance callers from other Indonesian cities must dial 0742 followed by the local number.
• International callers should replace the leading zero with +62 and then dial 742 and the local number.
• Always verify the exact number of digits with the subscriber, as local numbers may vary in length.
