Area Code 4 – Malampa

Overview of Vanuatu's +678 4 Geographic Prefix

The country calling code +678 is assigned to the Republic of Vanuatu under the ITU-T E.164 international numbering plan. Within the national numbering plan, the prefix 4 is designated as a geographic National Destination Code (NDC) for the Malampa Province. This province is located in the central region of the Vanuatu archipelago and encompasses the islands of Malakula, Ambrym, and Paama. The administrative center of Malampa is Lakatoro, situated on Malakula Island.

Geographic Coverage and Major Localities

The +678 4 prefix serves both fixed-line PSTN subscribers and, in some cases, fixed wireless terminals within the province. Key towns and villages covered by this code include Lakatoro, Norsup, and the surrounding settlements on Malakula, as well as communities on Ambrym and Paama. It is important to note that this is a geographic code, meaning the number is tied to a physical location and does not follow the subscriber if they relocate outside the Malampa area.

Dialing Formats and Caller Instructions

For callers dialing from within Vanuatu, the national format requires dialing the trunk prefix 0 followed by the NDC and the subscriber number. For example, to call a fixed line in Malampa from Port Vila, you would dial: 0 4 XXX XXX. The complete national number is typically 7 digits in length (including the leading 0).

For international callers, the correct format is: +678 4 XXX XXX (or 011 678 4 XXX XXX from North America). The leading '0' is omitted when dialing from abroad. For instance, to call a number in Lakatoro from outside Vanuatu, you would dial +678 4 123 456 (where 123 456 is the local subscriber number).

Numbering Plan and Overlay Considerations

Vanuatu's numbering plan is relatively straightforward, with geographic NDCs ranging from 2 to 8 for different provinces. Currently, there is no overlay code for Malampa; the 4 prefix is exclusive to this province. As of the latest ITU-T operational bulletin, no major renumbering or overlay is planned, but telecom authorities periodically review numbering resources to accommodate growth.

Practical Advice for Callers

When placing a call to a Malampa number, always verify the complete number, as the subscriber number length is fixed. For local callers within Vanuatu, using the national dialing format is mandatory. For international callers, ensure you have the correct country code and drop the trunk prefix. If you experience difficulties, check with your service provider for any specific dialing requirements for Vanuatu.
