Area Code 276 – Boyolali

Geographic Overview

The +62 276 country/area code combination corresponds to the Boyolali geographic region in Central Java, Indonesia. Boyolali is a regency (kabupaten) located approximately 25 kilometers south of the provincial capital, Semarang, and is known for its dairy farming and scenic views of Mount Merbabu and Mount Merapi. The area code 276 is part of the national numbering plan administered by the Indonesian Telecommunication Regulatory Authority (BRTI) under the Ministry of Communication and Information Technology.

Dialing Formats

For domestic callers within Indonesia, the trunk prefix '0' is used before the area code. Therefore, to call a fixed-line number in Boyolali from another Indonesian city, you would dial: 0-276-XXXXXXX. The local subscriber number typically consists of 7 to 8 digits, depending on the specific exchange and the number of lines in service. For example, a local Boyolali number might appear as (0276) 1234567.

For international callers, the country code +62 is used, and the leading '0' of the trunk prefix is omitted. Thus, the international dialing format becomes: +62 276-XXXXXXX. For instance, if the local number is 1234567, an international caller would dial +62 276 1234567.

Caller Instructions

• Local callers within Boyolali: If you are calling from another fixed-line number within the same area code, you may be able to dial just the local subscriber number without the area code, depending on your service provider and the specific exchange. However, for reliability, it is recommended to always include the area code, especially when calling from mobile phones.
• Domestic callers from other regions in Indonesia: Dial 0-276 followed by the subscriber number.
• International callers: Dial your country's international access code (e.g., 011 from the US, 00 from most European countries), then 62, then 276, and then the subscriber number. Do not dial the leading '0'.

Overlay and Numbering Considerations

As of the latest updates, there is no overlay code for the Boyolali area; 276 remains the sole area code for this region. However, due to the growth of mobile telephony and VoIP services, callers should be aware that numbers starting with 276 are exclusively assigned to fixed-line services. Mobile numbers in Indonesia always begin with 8 (e.g., 0811, 0821), and are not tied to a geographic area. Therefore, if you receive a call from a number starting with +62 276, it is originating from a fixed line in the Boyolali area.

When dialing from abroad, ensure you have the correct country code (+62) and omit the trunk prefix '0'. Also, be aware of time zone differences (Indonesia Western Time, UTC+7) to avoid calling at inconvenient hours.
