Area Code 923 – Morotai

Overview of Area Code 923 (Morotai, Indonesia)

Area code 923 is a geographic National Destination Code (NDC) assigned to the Morotai Island Regency, part of the North Maluku province in Indonesia. It serves the administrative center of Daruba and surrounding villages on Morotai Island, as well as adjacent smaller islands within the regency. The code is used for fixed-line (PSTN) services, including traditional copper lines and, increasingly, fixed-wireless access (FWA) and VoIP-based local telephony.

Dialing Formats

When calling a Morotai fixed-line number from within Indonesia, subscribers must dial the trunk prefix 0, followed by the area code 923, and then the local subscriber number. The complete national format is 0-923-XXXX, where XXXX represents the 4-digit local number. For example, a local number might be dialed as 0923-1234.

For international callers, the Indonesian country code +62 replaces the trunk prefix. The international dialing format becomes +62 923 XXXX. For instance, to call a Morotai number from abroad, one would dial +62 923 1234. Note that the leading zero is omitted when using the country code.

Geographic Coverage and Administration

Morotai Island Regency is one of the regencies in North Maluku, with its capital in Daruba. The area code 923 covers the entire regency, including the districts of Morotai Selatan, Morotai Selatan Barat, Morotai Jaya, Morotai Utara, and Morotai Timur. The region is known for its historical significance during World War II and is currently developing as a special economic zone, which may drive future telecommunication infrastructure expansion.

Calling Instructions

• Local callers (within Morotai): For calls within the same area code, local numbers can often be dialed directly without the area code, depending on the operator's dialing plan. However, to ensure connectivity, it is recommended to dial the full national format 0923-XXXX.
• Domestic long-distance callers (outside Morotai): Dial 0-923-XXXX.
• International callers: Dial your country's exit code, then 62 923 XXXX. For example, from the US, dial 011 62 923 1234.

Numbering and Overlay Considerations

As of the latest ITU-T E.164 national numbering plan updates, there is no overlay code for the Morotai area. The subscriber number length is typically 4 digits, resulting in a total national significant number (NSN) length of 9 digits (including the leading 0). The Indonesian Telecommunication Regulatory Authority (BRTI) manages the allocation of numbers, and no major changes have been announced that would affect the 923 area code in the near future.
