Area Code 401 – Kendari

Geographic Coverage and Administrative Jurisdiction

The area code 401 is a geographic National Destination Code (NDC) assigned to the city of Kendari, the capital of Southeast Sulawesi Province (Sulawesi Tenggara) in Indonesia. This code serves the municipality of Kendari and its immediate metropolitan surroundings, including parts of the adjacent Konawe Regency. As a geographic code, it is tied to the PSTN infrastructure of the region, with numbers typically associated with fixed-line services, though some VoIP and wireless local loop services may also use this code.

Dialing Formats and Caller Instructions

For callers within Indonesia, the local dialing format requires the trunk prefix 0 followed by the area code and the subscriber number. For example, to call a fixed line in Kendari from another Indonesian city, you would dial: 0401-XXXXXXX (where XXXXXXX is the 7-digit local subscriber number). If you are calling from within Kendari itself, you may be able to omit the area code and dial just the 7-digit number, depending on the incumbent operator's local calling rules. However, for clarity and to avoid misdials, it is recommended to always use the full national format.

For international callers, the country code for Indonesia is +62. The international dialing format is: +62 401 XXXXXXX. Note that the leading 0 of the national trunk prefix is dropped when dialing from abroad. For example, a caller from the United States would dial: 011 62 401 XXXXXXX (using the international access code from their country).

Numbering Plan Details and Overlays

As of the current Indonesian numbering plan (ITU-T E.164), the subscriber numbers in the 401 area code are typically 7 digits long, resulting in a total national significant number length of 10 digits (including the leading 0). There is no overlay code in this region; the 401 code is exclusively assigned to Kendari and its immediate service area. However, the rapid growth of telecommunications services in the region may lead to future numbering expansions, so it is advisable to verify the exact number length with your local service provider.

Practical Guidance for Callers

• Local callers (within Indonesia): Use the national format 0401-XXXXXXX.
• International callers: Use +62 401 XXXXXXX.
• Mobile calls: When calling a mobile phone in Kendari, note that mobile numbers use different prefixes (e.g., 0811, 0821, etc.) and are not part of the 401 geographic code.
• Emergency and special services: Always dial national emergency numbers (e.g., 110 for police, 112 for general emergencies) rather than using the area code.

Understanding the correct dialing format ensures that your calls to Kendari are connected efficiently and without unnecessary charges. Always confirm the exact subscriber number with the party you are trying to reach, as number lengths may vary.
