Overview of Area Code 966 (Sarmi, Indonesia)

Area code 966 is a geographic National Destination Code (NDC) assigned to the Sarmi Regency, located in the province of Papua, Indonesia. This code is part of the Indonesian national numbering plan, which adheres to ITU-T E.164 recommendations. The Sarmi region encompasses the administrative capital Sarmi and its surrounding districts, including coastal areas along the northern coast of Papua. When dialing a fixed-line number in Sarmi from within Indonesia, subscribers must include the trunk prefix '0' followed by the area code and the subscriber number. For international callers, the country code for Indonesia (+62) replaces the leading '0'.

Dialing Formats

Local calls within Sarmi (same area code) typically require only the subscriber number, though some areas may require the area code depending on local dialing rules. For calls from other Indonesian regions, the format is: 0 966 XXX XXXX. International callers should dial: +62 966 XXX XXXX. The subscriber number length may vary, but the total number of digits after the country code and trunk prefix is typically 7 to 8 digits. Always verify the exact subscriber number length with your local provider or the recipient.

Caller Instructions

• Local callers within Sarmi: If you are calling from a fixed-line phone within the same area code, you may dial only the local subscriber number. However, if your phone system requires full national dialing, use the '0' prefix.
• Callers from other Indonesian regions: Dial 0 966 followed by the subscriber number. For example, to call a Sarmi number 1234567, dial 0966 1234567.
• International callers: Dial your country's international access code (e.g., 00 from many countries), then 62 966 and the subscriber number. For instance, from the US, dial 011 62 966 1234567.

Overlay and Numbering Considerations

As of the latest updates, there are no overlay codes for Sarmi. The area code 966 is exclusively used for geographic fixed-line services in this region. Mobile numbers in Indonesia are non-geographic and begin with different prefixes (e.g., 081x, 082x, etc.) and are not tied to this area code. If you are trying to reach a mobile phone in Sarmi, you must dial the mobile number directly, which includes the mobile network prefix. For fixed-line services, ensure you have the correct area code to avoid misdialing. Number portability may allow fixed-line numbers to be moved between operators, but the geographic area code generally remains associated with the original location.
