Area Code 5 – Savaii

Overview of Samoa's +685 5 Geographic Code

In Samoa's national numbering plan, the prefix 5 is designated as a geographic area code for the island of Savai'i, the country's largest island and a major administrative region. This code is part of Samoa's PSTN (Public Switched Telephone Network) and is used for fixed-line services within the Savai'i district. The numbering plan follows ITU-T E.164 standards, with the full international format being +685 5XX XXXX (where X represents the subscriber number digits).

Geographic Coverage and Administration

Savai'i is Samoa's second-most populous island, with key towns including Salelologa, the main port and commercial hub, and the capital, Asau. The 5 prefix serves both residential and business fixed-line customers across the island's villages and administrative districts. Calls to this code are routed through Samoa's national telecommunication infrastructure, which is operated primarily by the Samoa Submarine Cable Company and local carriers such as SamoaTel and Digicel Samoa.

Dialing Formats and Caller Instructions

For callers within Samoa, dialing a Savai'i fixed-line number requires the national trunk prefix 0 followed by the area code and subscriber number: 0 5 XX XXXX. For example, a local call to a number in Salelologa would be dialed as 0 5 123 4567. International callers must use Samoa's country code +685 and omit the leading trunk prefix, resulting in +685 5 123 4567. When calling from Samoa to another country, the international access prefix is 00 (e.g., 00 1 202 555 0123 for the US).

Overlay and Numbering Considerations

Currently, there is no overlay code for Savai'i; the 5 prefix is exclusive to the island's fixed-line network. However, Samoa's telecommunications regulator, the Office of the Regulator (OOTR), has implemented number portability, allowing subscribers to retain their numbers when changing service providers. This means that a number beginning with 5 may occasionally be served by a different carrier, but it remains geographically associated with Savai'i for billing and emergency services purposes.

It is important to note that mobile numbers in Samoa use the prefixes 7 (Digicel) and 8 (SamoaTel), which are non-geographic. Therefore, a number starting with 5 is always a fixed-line service and should be dialed accordingly. For businesses, having a Savai'i number can enhance local presence, but for international callers, it is essential to use the correct international format to avoid call failures.
