Area Code 274 – Yogyakarta

Geographic Coverage and Administrative Jurisdiction

The +62 274 country and area code combination corresponds to the Special Region of Yogyakarta (Daerah Istimewa Yogyakarta, DIY) on the island of Java, Indonesia. This numbering area is administered under the national numbering plan of the Indonesian Telecommunication Regulatory Authority (BRTI) and is classified as a geographic code, meaning it is tied to a specific PSTN exchange area. The coverage includes the city of Yogyakarta (Kota Yogyakarta) and its surrounding urban agglomeration, which encompasses Sleman Regency to the north, Bantul Regency to the south, and parts of Kulon Progo and Gunung Kidul regencies. As the capital of the Special Region, Yogyakarta is a major cultural and educational hub, home to institutions such as Gadjah Mada University and the Sultan's Palace (Kraton).

Dialing Formats and Caller Instructions

For domestic callers within Indonesia, the trunk prefix '0' is used before the area code. Therefore, to call a fixed-line number in Yogyakarta from another part of Indonesia, you would dial 0-274-XXXXXXX, where 'XXXXXXX' represents the local subscriber number, which typically consists of 7 digits. For example, a local number might be formatted as 0274-1234567.

For international callers, the country code +62 is used, followed by the area code without the leading '0'. Thus, the same number would be dialed as +62 274-XXXXXXX or +622741234567 when using the full international format. When calling from abroad, you must replace the '+' with your country's international exit code (e.g., '011' from the US, '00' from most European countries).

Overlay and Numbering Considerations

As of the latest updates, there is no overlay code for the Yogyakarta area; the 274 code remains the sole geographic area code for fixed-line services in this region. However, the rapid growth of VoIP and mobile services has led to an increased number of non-geographic numbers that may appear to have local prefixes. It is important to note that mobile numbers in Indonesia always begin with '08' and are not tied to geographic regions, so they cannot be reached via the 274 area code.

For callers within Yogyakarta, local calls may be made using only the subscriber number (7 digits) without the area code, depending on the specific carrier and local dialing regulations. However, for clarity and to avoid misdialing, it is recommended to always include the area code when dialing from a mobile phone or from outside the immediate local calling area.
