Area Code 522 – Ampah

Overview of Area Code 522

Area code 522 is a geographic National Destination Code (NDC) assigned to the region of Ampah in Indonesia. Ampah is a district located in the Barito Timur Regency (East Barito) within the province of Central Kalimantan (Kalimantan Tengah), on the island of Borneo. This code is part of the Indonesian national numbering plan, which follows ITU-T E.164 recommendations.

Geographic Coverage and Administrative Jurisdiction

The 522 area code serves the administrative area of Ampah and its surrounding villages. Ampah is the capital of Barito Timur Regency and is situated along the Barito River. The region is primarily known for its agriculture, rubber plantations, and small-scale mining activities. The code covers the local exchanges within the regency, including areas like Tamiang Layang, which is the regency seat, and other nearby settlements.

Dialing Formats

When calling a fixed-line number in Ampah from within Indonesia, the trunk prefix 0 is used before the area code. The national significant number (NSN) for geographic numbers in Indonesia is typically 8 to 10 digits, including the area code. For Ampah, local numbers are usually 5 to 7 digits after the area code, making the complete national number format: 0-522-XXXXXXX.

For international callers, the country code for Indonesia is +62. The leading trunk prefix '0' is dropped, so the international format becomes: +62 522 XXXXXXX. For example, if a local number is 12345, the national dialing format would be 0522 12345, and the international format would be +62 522 12345.

Caller Instructions

• Local callers (within Ampah): If you are calling from a fixed line within the same area code, you may be able to dial just the local number without the area code, depending on the operator's local dialing rules. However, for clarity and to avoid misdialing, it is recommended to always include the area code, especially when calling from mobile phones.
• National callers (outside Ampah): Dial 0 followed by 522 and then the local number. Example: 0522 12345.
• International callers: Dial your country's exit code (e.g., 00 or 011), then 62, then 522, and the local number. Example: +62 522 12345.

Overlay and Numbering Considerations

As of the latest ITU-T operational bulletin, there are no overlay codes for the 522 area. The numbering capacity is sufficient for the current demand. However, with the expansion of telecommunication services, the Indonesian regulatory authority (BRTI) may introduce additional digits or overlay codes in the future. It is always advisable to check the latest local dialing instructions when placing calls.

For businesses and individuals in Ampah, having a geographic number with the 522 code establishes a local presence and can be more cost-effective for customers calling from the region. VoIP services also allow routing to these numbers, but the geographic nature of the code means that the call is terminated at a fixed-line exchange in the Ampah area.
