Area Code 325 – Sangkapura

Overview of Area Code +62 325

The +62 325 country and area code combination corresponds to the Sangkapura geographic numbering area in Indonesia. Sangkapura is the principal town on Bawean Island, administratively part of Gresik Regency in East Java province. This code is allocated under Indonesia's National Numbering Plan (ITU-T E.164) for fixed-line telephone services within the Sangkapura exchange area.

Geographic Coverage and Administrative Jurisdiction

The +62 325 area code serves the entire Bawean Island, which includes the districts (kecamatan) of Sangkapura and Tambak. Bawean Island is located in the Java Sea, approximately 120 kilometers north of the main Java island. The administrative center, Sangkapura, is the largest settlement and hosts the primary telephone exchange. The code covers all fixed-line subscribers within the island's two districts, including villages such as Kepuhlegundi, Sungai Rujing, and others under Sangkapura District, and the coastal communities of Tambak District.

Dialing Formats and Caller Instructions

For callers within Indonesia, the trunk prefix '0' is used before the area code. To call a Sangkapura fixed-line number from another Indonesian city, dial: 0 325 XXX XXX (where X represents the local subscriber number). For example, a local number might be dialed as 0325 123 456.

For international callers, the Indonesian country code +62 is used, and the leading '0' of the trunk prefix is dropped. The international dialing format is: +62 325 XXX XXX. For instance, to call a Sangkapura number from abroad, you would dial +62 325 123 456.

Local calls within the Sangkapura area (same area code) may be made using the 7-digit subscriber number without the area code, depending on the local dialing plan. However, it is always safe to include the area code when dialing from a mobile phone or from outside the local exchange area.

Overlay and Numbering Considerations

As of the latest updates, there is no overlay code for the Sangkapura area. The 325 area code is exclusively assigned to fixed-line services on Bawean Island. Subscriber numbers in this area are typically 7 digits long, resulting in a total national significant number length of 10 digits (including the area code). No mobile network prefixes are associated with this geographic code; mobile services on the island use separate non-geographic prefixes (e.g., 0811, 0812, etc.) assigned to national mobile operators.

Practical Usage for Callers

For local callers within Indonesia: always use the trunk prefix '0' when dialing from a different area code. For example, from Jakarta, you would dial 0325 123 456. For international callers: use the plus sign (+) or the international access prefix of your country, followed by 62, then the area code without the leading '0', and the subscriber number. Example: +62 325 123 456.

It is important to note that while Indonesia has implemented mobile number portability, fixed-line numbers are generally not portable across different geographic areas. The +62 325 code remains tied to the Sangkapura exchange, ensuring that calls are routed efficiently to the correct island destination.
