Area Code 275 – Purworejo

Overview of Area Code +62 275

Area code 275 is a geographic National Destination Code (NDC) within the Indonesian public switched telephone network (PSTN), assigned under the international country calling code +62. It serves the Purworejo region, which is located in the southern part of Central Java Province. The administrative coverage includes the Purworejo Regency (Kabupaten Purworejo) and its surrounding districts, with the city of Purworejo as the primary urban center. This code is part of the legacy fixed-line telephony infrastructure, operated predominantly by PT Telkom Indonesia and other licensed local fixed-line operators.

Geographic Coverage and Dialing Conventions

The +62 275 area code encompasses a mix of urban and rural areas, including towns such as Kutoarjo, Kemiri, and Pituruh. For local callers within the same NDC, the trunk prefix 0 is used, followed by the area code and the subscriber number, omitting the country code. For example, a local call to a fixed line in Purworejo would be dialed as 0275-XXXXXXX (where X denotes the local subscriber number, typically 5 to 7 digits). International callers must replace the trunk prefix with the Indonesian country code +62, resulting in the format +62 275-XXXXXXX. When dialing from a mobile phone within Indonesia, the same international format is often used, though the trunk prefix may also be accepted depending on the carrier.

Numbering Structure and Overlays

Subscriber numbers under the 275 NDC vary in length, but the total length of the national significant number (NSN) for geographic numbers in Indonesia is typically 9 to 11 digits, including the leading '0' of the area code. Currently, no overlay codes have been introduced for the Purworejo area; the 275 code remains the sole geographic identifier for fixed-line services in this region. However, due to the growth of VoIP and mobile services, some numbers may be routed over IP networks, but the dialing format remains unchanged.

Caller Instructions

For local callers: dial 0275 followed by the subscriber number. For domestic long-distance callers from other Indonesian area codes: dial 0-275-XXXXXXX. For international callers: dial your country's exit code (e.g., 00 or 011), then 62, then 275, and finally the subscriber number, omitting the leading '0'. Ensure to check the exact subscriber number length, as it may vary. For emergency or directory assistance services, use the national numbers (e.g., 112 for emergencies) rather than area-specific codes.
