Area Code 64 – Apia

Overview of Samoa's +685 64 Geographic Prefix

The +685 64 prefix is a geographic National Destination Code (NDC) assigned to the Apia urban area, the capital and largest city of Samoa. Apia is located on the northern coast of Upolu Island and serves as the country's political, economic, and administrative hub. This prefix is used for fixed-line (PSTN) services within the Apia exchange area, covering residential, business, and government subscribers.

Dialing Formats and Usage

When calling a number with the +685 64 prefix from abroad, the international format is +685 64XX XXXX (where X represents the subscriber's unique digits). For example, a local Apia number might be dialed as +685 64 123 456. Within Samoa, callers dial the full 8-digit national number, which includes the NDC and subscriber number: 64 123 456. No trunk prefix (like '0') is used in Samoa; the national significant number (NSN) is 8 digits in length, with the NDC being the first two digits.

Geographic Coverage and Administrative Jurisdiction

The 64 prefix is specific to the Apia urban zone, which encompasses the central business district, government buildings, and surrounding residential neighborhoods. It does not cover other regions of Upolu or the island of Savai'i, which have their own distinct NDCs. The prefix is administered by the Samoa Regulator (Office of the Regulator) and allocated to the incumbent fixed-line operator, SamoaTel, though alternative licensed carriers may also offer fixed services in the area.

Caller Instructions

For international callers, always replace the leading '+' with the appropriate international access code (e.g., 011 from the US/Canada, 00 from most European countries) before dialing. For example, from the US, dial 011 685 64 123 456. For local callers, simply dial the 8-digit number starting with 64. If you are calling from a mobile phone within Samoa, you can dial the number in the same format; there is no need to add an area code beyond the NDC.

Overlay and Numbering Considerations

As of the latest ITU-T E.164 national numbering plan, Samoa has not implemented overlay codes for Apia; the 64 prefix remains the sole geographic code for the city. However, with the ongoing migration of fixed-line services to VoIP and NGN (Next-Generation Networks), some numbers may be routed over IP infrastructure, but the geographic significance of the prefix is retained for number portability and regulatory purposes. Users should note that while the prefix is geographically tied to Apia, it does not necessarily indicate the physical location of the called party if number portability has been applied, though this is rare for fixed lines in Samoa.
