Area Code 28 – Niutao

Overview of Tuvalu's +688 28 Geographic Code

The country calling code +688 is assigned to Tuvalu, a Polynesian island nation located in the Pacific Ocean. Within the Tuvalu numbering plan, the prefix 28 is a geographic area code designated for the island of Niutao. Niutao is a remote coral atoll in the northern part of Tuvalu, with a small population and limited telecommunications infrastructure. The +688 28 code is used for fixed-line telephone services on the island, connecting residents and the few businesses present to the national and international PSTN.

Dialing Formats and Usage

For callers within Tuvalu, dialing a Niutao number requires the trunk prefix '1' followed by the area code '28' and the subscriber's local number. For example, a local call to a Niutao subscriber with the number 1234 would be dialed as 1 28 1234. International callers must dial the Tuvalu country code +688, then the area code 28 (without the leading trunk prefix), followed by the local number. Thus, the same Niutao number would be dialed internationally as +688 28 1234. It is important to note that Tuvalu's numbering plan uses variable-length subscriber numbers, and the total length after the country code may vary. However, the area code 28 is fixed for Niutao.

Geographic and Administrative Context

Niutao is one of Tuvalu's nine inhabited islands, with a land area of approximately 2.53 square kilometers and a population of around 600 people. The island's main village is Kulia, and its economy is primarily subsistence-based, with some reliance on fishing and copra production. Telecommunications services on Niutao are provided by the state-owned Tuvalu Telecommunications Corporation (TTC), which operates the fixed-line network. Due to the island's small size and remote location, the number of active landlines under the 28 prefix is very limited, and the infrastructure is basic, often relying on satellite backhaul for international connectivity.

Caller Instructions and Considerations

For local callers within Tuvalu, dialing a Niutao number requires the trunk prefix '1' followed by the area code '28' and the subscriber's local number. For example, a local call to a Niutao subscriber with the number 1234 would be dialed as 1 28 1234. International callers must dial the Tuvalu country code +688, then the area code 28 (without the leading trunk prefix), followed by the local number. Thus, the same Niutao number would be dialed internationally as +688 28 1234. It is important to note that Tuvalu's numbering plan uses variable-length subscriber numbers, and the total length after the country code may vary. However, the area code 28 is fixed for Niutao.

When calling from abroad, ensure you have the correct international exit prefix for your country (e.g., 011 from the US, 00 from most European countries). Also, be aware that Tuvalu has limited international bandwidth, so call quality may be affected. For VoIP or satellite calls, the same international format applies. There are no known overlay codes for Niutao, so the 28 prefix is unique to this island.
