📍 Geographic Location of Madang

Geographic Overview of Area Code 42

Area code 42 is a geographic National Destination Code (NDC) within the Papua New Guinea (PNG) numbering plan, assigned to the province of Madang. This code is used for fixed-line PSTN services and is administered under the national regulatory framework of the National Information and Communications Technology Authority (NICTA). Geographically, the code covers the administrative district of Madang, including the provincial capital Madang City and surrounding rural areas along the north coast of the mainland.

Dialing Formats and Usage

When dialing a fixed-line number in Madang from within Papua New Guinea, the national format is 42X XXXX, where the full national significant number (NSN) is eight digits, beginning with the NDC '42'. For example, a local subscriber number might be 422 1234. To call this number from another province within PNG, you must dial the national trunk prefix 0, followed by the NDC and the subscriber number: 0 42 2 1234.

For international callers, the correct format is the international access prefix (typically + or 00), followed by the country code 675, then the NDC and subscriber number without the leading '0'. Thus, a caller from the United States would dial +675 42 2 1234. This format is essential for routing calls correctly through international gateways.

Caller Instructions

  • Local callers within Madang: If you are dialing a number within the same area code, you may often omit the trunk prefix and NDC, but it is recommended to always use the full national format (0 42 X XXXX) to avoid confusion.
  • National callers from other provinces: Always dial 0 before the NDC. Example: 0 42 2 1234.
  • International callers: Dial your country's exit code (e.g., 011 from the US), then 675, then the NDC and subscriber number. Example: 011 675 42 2 1234.

Overlay and Numbering Considerations

As of the latest NICTA updates, there is no overlay code for Madang; the area code 42 remains the sole geographic code for the province. However, with the ongoing migration to IP-based networks, some fixed-line numbers may be routed via VoIP, but the geographic significance of the code is preserved for number portability and emergency services. Callers should be aware that while mobile numbers in PNG are non-geographic and begin with 7 or 8, any number starting with 42 is a fixed-line service in Madang.
