Area Code 47 – Morobe

Overview of Area Code 47 (Morobe Province)

Area code 47 is a geographic National Destination Code (NDC) assigned to the Morobe Province of Papua New Guinea. This province is located on the northern coast of the mainland, with its administrative and commercial hub in the city of Lae, the second-largest city in the country. The code covers the entire province, including major towns such as Bulolo, Wau, Menyamya, and Finschhafen, as well as numerous rural districts.

In the Papua New Guinea national numbering plan, geographic area codes are used for fixed-line (PSTN) services. The full national significant number (NSN) for a fixed-line subscriber in Morobe consists of the area code (47) followed by a subscriber number, typically totaling 7 digits in the format 47X XXXX. The exact length may vary depending on the local exchange capacity and historical allocations.

Dialing Formats

When calling a fixed-line number in Morobe from within Papua New Guinea, you must dial the trunk prefix 0 followed by the area code and subscriber number. For example, to reach a number in Lae, you would dial:

• National format: 0 47 123 456

For international callers, the country code for Papua New Guinea is +675. The leading 0 is omitted. Thus, the same number is dialed as:

• International format: +675 47 123 456

This format is consistent with ITU-T E.164 recommendations, ensuring global interoperability.

Geographic Coverage and Administrative Significance

Morobe Province is one of the most economically important regions in Papua New Guinea, largely due to the presence of the Lae port and its role as a gateway for trade and industry. The area code 47 is therefore associated with a high concentration of businesses, government offices, and residential fixed-line services. The province is divided into districts, each with its own local exchanges, but all share the same NDC 47.

Overlay and Numbering Considerations

Currently, there is no overlay code for Morobe; the 47 code is exclusively used for geographic fixed-line services within the province. However, as with many countries, the telecommunications regulator (National Information and Communications Technology Authority - NICTA) periodically reviews numbering resources. Should demand exceed capacity, an overlay may be introduced, requiring 10-digit dialing (including the trunk prefix) for all local calls. At present, local calls within the same exchange may be possible without the area code, but for clarity and future-proofing, it is recommended to always use the full national format.

Caller Instructions

For local callers (within Papua New Guinea): Always dial 0 before the area code when calling from a different province or mobile network. If you are calling from a fixed-line within the same exchange, you might be able to dial only the subscriber number, but this is not guaranteed across all networks.

For international callers: Dial your country's international access code (e.g., 011 from the US, 00 from most European countries), followed by 675, then 47 and the subscriber number. Do not include the leading 0.

Always verify the number length with the recipient, as some older lines may have fewer digits.
