Kolonedale is located in the Tojo Una-Una Regency, within the province of Central Sulawesi (Sulawesi Tengah). This code is part of the Indonesian public switched telephone network (PSTN) and is used for fixed-line services in this area.

Geographic Coverage and Administrative Jurisdiction

The 465 area code serves Kolonedale and its surrounding administrative districts within Tojo Una-Una Regency. The regency is situated on the eastern coast of Central Sulawesi, facing the Gulf of Tomini. The primary town associated with this code is Kolonedale, which acts as the administrative center of the regency. Other nearby settlements and villages within the regency may also be served by this code, depending on the local telecommunications infrastructure.

Dialing Formats and Instructions

For callers within Indonesia, dialing a fixed-line number in Kolonedale requires the trunk prefix '0' followed by the area code and the subscriber number. The national format is: 0 465 XXX XXXX (where X represents the subscriber digits). For example, if the subscriber number is 123 4567, the national dialing format would be 0465 123 4567.

For international callers, the Indonesian country code (+62) is used, and the leading '0' of the trunk prefix is omitted. The international format is: +62 465 XXX XXXX. Using the same example, the international dialing format would be +62 465 123 4567.

Caller Instructions

Local callers (within Indonesia): If you are calling from another area code within Indonesia, you must dial the trunk prefix '0' first. For instance, from Jakarta, you would dial 0465 123 4567. If you are calling from a mobile phone, you can also use the same format.

Foreign callers (outside Indonesia): When calling from abroad, you need to dial your country's international access code (e.g., 011 from the US, 00 from most European countries), followed by Indonesia's country code 62, then the area code without the leading '0', and finally the subscriber number. For example, from the US, you would dial 011 62 465 123 4567.

Overlay and Numbering Considerations

As of the latest ITU-T E.164 national numbering plan updates, there is no overlay code for the 465 area code. The area code is unique to the Kolonedale region, and no additional area codes have been overlaid onto this geographic region. Subscriber numbers within this area typically consist of 7 to 8 digits, but the total length of the national significant number (NSN) for Indonesia is 9 to 12 digits, including the area code. For the 465 area code, the NSN is typically 10 to 11 digits (excluding the trunk prefix '0').

It is important to note that while fixed-line services are the primary use for this code, some VoIP services may also be assigned numbers with this geographic code, but they are still considered location-based for routing purposes.
