Area Code 3 – NCD

Overview of Papua New Guinea Area Code 3

Area code 3 is the National Destination Code (NDC) for the National Capital District (NCD) of Papua New Guinea, which encompasses the capital city of Port Moresby and its immediate urban periphery. As a geographic code, it is allocated under the ITU-T E.164 national numbering plan of Papua New Guinea and is used exclusively for fixed-line (PSTN) services within this administrative region.

Geographic Coverage and Administrative Jurisdiction

The NCD is a federal district that serves as the national seat of government and the economic hub of the country. The area code covers all landline subscribers within the district boundaries, including central business areas, government precincts (e.g., Waigani, where Parliament and government departments are located), and residential suburbs such as Boroko, Gordons, and Hohola. It does not extend to other provinces, which have their own distinct area codes (e.g., 4 for Eastern Highlands, 5 for Northern, etc.).

Dialing Formats and Procedures

For callers within Papua New Guinea, the national trunk prefix is 0. To call a fixed line in Port Moresby, you must dial 0 followed by the area code 3 and then the 7-digit local subscriber number. For example, a local number might be formatted as 312 3456. Thus, the complete national dialing sequence is 0 3 123 456 (or 03 123 456 when written with the trunk prefix).

For international callers, the country code for Papua New Guinea is +675. You must omit the leading trunk prefix 0 and dial the country code, area code, and subscriber number. Using the same example, an international caller would dial +675 3 123 456. This format is essential for routing calls correctly through international gateways.

Overlay and Numbering Considerations

Currently, there is no overlay code for the NCD; the area code 3 is unique to this region. However, as demand for fixed-line services grows, the National Information and Communications Technology Authority (NICTA) may introduce overlay plans in the future. Subscribers within the NCD do not need to dial the area code for local calls within the same district—only the 7-digit subscriber number is required. For calls from other provinces, the full national format (0 3 …) is mandatory.

Practical Guidance for Callers

• Local callers (within NCD): Dial only the 7-digit subscriber number (e.g., 123 456).
• National callers (outside NCD): Dial 0, then 3, then the subscriber number (e.g., 0 3 123 456).
• International callers: Dial your country's exit code, then +675, then 3, then the subscriber number (e.g., 011 675 3 123 456 from the US).

This structure ensures efficient routing and helps avoid misdialing. Always verify the subscriber number length, as fixed-line numbers in Papua New Guinea are consistently 7 digits after the area code.
