Area Code 50 – ‘Eua

Overview

The +676 50 prefix is a geographic area code assigned to the island of ‘Eua in the Kingdom of Tonga. ‘Eua is one of Tonga’s main inhabited islands, located southeast of the main island of Tongatapu. The prefix is used for fixed-line telephone services within the ‘Eua island group, covering the administrative district of ‘Eua and its principal villages, including ‘Ohonua, Pangai, and Tufuvai. As a geographic code, it is tied to the physical location of the subscriber’s line, and calls are routed over the PSTN (Public Switched Telephone Network) to the local exchange serving the island.

Dialing Formats

When calling a number in ‘Eua from within Tonga, subscribers must dial the national trunk prefix 0 followed by the area code 50 and the local subscriber number. The complete national format is 0 50 XXXX, where XXXX represents the 4-digit local line number. For example, a local call to a subscriber in ‘Ohonua would be dialed as 0 50 1234.

From outside Tonga, callers must use the international access prefix (typically 00 or +), followed by the Tonga country code 676, then the area code 50 (without the leading trunk zero) and the local number. The international format is +676 50 XXXX. For instance, an international caller would dial +676 50 1234 to reach the same subscriber.

Caller Instructions

• Local callers (within Tonga): Dial 0 50 XXXX (e.g., 0 50 5678).
• International callers: Dial your country’s exit code, then 676 50 XXXX (e.g., from the US/Canada, dial 011 676 50 5678; from most European countries, dial 00 676 50 5678).

Regulatory and Technical Notes

Geographic numbering in Tonga is managed by the Tonga Communications Commission (TCC) in accordance with ITU-T E.164 recommendations. The 50 prefix is allocated exclusively to fixed-line services on ‘Eua, and it is not portable to other islands or to mobile networks. As of the current numbering plan, there are no overlay codes for ‘Eua; the 50 code is unique to the island. Subscribers on ‘Eua may also have access to VoIP and mobile services, but those services use separate non-geographic prefixes. When dialing from a mobile phone within Tonga, the same trunk prefix (0) is used, but some mobile users may need to include the area code even when calling locally, depending on their service provider’s dialing plan.

For businesses or individuals on ‘Eua, it is important to display the number in international format (+676 50 XXXX) on websites and global directories to ensure correct routing from overseas. The fixed-line network on ‘Eua is connected via submarine cable and microwave links to the main island of Tongatapu, ensuring reliable voice services.
