Area Code 298 – Salatiga/Ambarawa

Geographic Coverage and Administrative Jurisdiction

Area code 298 is a geographic National Destination Code (NDC) assigned to the Salatiga and Ambarawa regions in Central Java, Indonesia. Salatiga is an independent city (Kota) with its own municipal government, while Ambarawa is a district (Kecamatan) in Semarang Regency. The code covers the urban and suburban areas of Salatiga, Ambarawa, and their immediate surroundings, including the towns of Bawen, Tuntang, and Bringin. These areas are located on the main road between Semarang and Yogyakarta, making them important transit and economic hubs.

Dialing Formats and Caller Instructions

For callers within Indonesia, the domestic trunk prefix 0 is used before the area code. To call a fixed-line number in Salatiga or Ambarawa, dial 0-298-XXXXXXX, where the subscriber number is typically 7 digits long. For example, a local number might be 0-298-5123456.

For international callers, the Indonesian country code +62 replaces the leading zero. The international format is +62-298-XXXXXXX. For instance, to reach the same number from abroad, you would dial +62 298 5123456. When dialing from a mobile phone, the plus sign (+) is usually entered by pressing and holding the 0 key.

Overlay and Numbering Considerations

Currently, there is no overlay code for the 298 area, meaning that local calls within the same area code do not require the area code; you can dial just the 7-digit subscriber number. However, for calls from outside the 298 area (including from mobile phones), the full national format with the trunk prefix must be used. The Indonesian numbering plan follows ITU-T E.164 recommendations, and the total length of a national significant number (NSN) for geographic numbers is typically 9 to 10 digits, including the leading 0.

Network and Service Providers

Fixed-line services in this region are primarily provided by PT Telkom Indonesia (the incumbent operator) and various regional fixed-line operators. The infrastructure supports traditional PSTN and increasingly VoIP-based services. Subscriber numbers are allocated to both residential and business customers. When calling from abroad, be aware of time zone differences (Indonesia Western Time, UTC+7) to avoid disturbing recipients.
