Area Code 411 – Makassar/Maros/Sungguminasa

Overview of Area Code +62 411

Area code 411 is a geographic National Destination Code (NDC) within the Indonesian numbering plan, assigned to the southern part of South Sulawesi province on the island of Sulawesi. The code serves the city of Makassar (the provincial capital), the adjacent regency of Maros, and the town of Sungguminasa (the capital of Gowa Regency). These areas form a contiguous metropolitan region often referred to as Mamminasata (Makassar–Maros–Sungguminasa–Takalar), although Takalar is served by a different code.

Geographic Coverage and Administrative Jurisdiction

The 411 code covers the municipalities of Makassar and the regencies of Maros and Gowa. Makassar is the largest city in eastern Indonesia and a major commercial hub, while Maros and Gowa are important suburban and agricultural areas. The region is governed under the South Sulawesi provincial administration, with Makassar serving as the provincial capital.

Dialing Formats

When calling a fixed-line number in the 411 area from within Indonesia (outside the local area), you must dial the trunk prefix 0, followed by the area code 411, and then the subscriber number. For example, to reach a number in Makassar from Jakarta, you would dial: 0411 123456.

For international callers, the format is: +62 411 123456 (drop the leading 0). Local calls within the 411 area (e.g., from Makassar to Maros) typically do not require the area code; you can dial just the 6- to 7-digit subscriber number.

Numbering Structure and Overlays

Subscriber numbers in the 411 area are typically 6 to 7 digits long. The total length of a national significant number (NSN) is 9 to 10 digits (including the leading 0 but excluding the country code). As of the latest ITU-T E.164 guidelines, there are no overlay codes in this region; 411 remains the sole geographic code for the area. However, with the growth of VoIP and mobile services, some numbers may be routed over IP networks, but the dialing format remains unchanged.

Caller Instructions

• Local callers (within 411): Dial only the subscriber number (e.g., 123456).
• National callers (outside 411): Dial 0-411-subscriber number (e.g., 0411 123456).
• International callers: Dial your country's exit code, then 62, then 411, then the subscriber number (e.g., +62 411 123456).

This area code is essential for businesses and residents in Makassar, a rapidly developing economic center. Understanding the correct dialing format ensures seamless connectivity for both domestic and international communications.
