Area Code 23 – Bairiki

Overview of Kiribati Area Code 23

Area code 23 is a geographic National Destination Code (NDC) assigned to Bairiki, the administrative and commercial center of Kiribati, located on the islet of Bairiki in South Tarawa. This code is part of the Kiribati national numbering plan, which follows ITU-T E.164 recommendations. The full international dialing format for numbers in this area is +686 23X XXXX, where the total number length after the country code is eight digits (including the NDC).

Geographic Coverage and Administrative Significance

Bairiki serves as the capital of the Republic of Kiribati and hosts key government offices, foreign embassies, and commercial enterprises. The 23 prefix covers the Bairiki islet and, in some cases, adjacent areas within South Tarawa. It is important to note that while Tarawa is a densely populated atoll, numbering assignments are typically localized to specific islets or exchanges.

Dialing Formats and Caller Instructions

For callers within Kiribati, the local dialing format is 23X XXXX (omitting the country code). For international callers, the format is +686 23X XXXX. When dialing from a mobile phone, the plus sign (+) is used to denote the international access prefix, followed by the country code and the national significant number.

For example, to call a landline in Bairiki with the number 234 5678:

• From within Kiribati: dial 234 5678.
• From overseas: dial +686 234 5678.

Overlay and Numbering Considerations

As of the latest ITU-T operational bulletins, Kiribati has not implemented overlay codes for geographic areas. The numbering plan is closed, meaning the NDC is required for all calls, including local calls, except for on-islet calls that may use shorter local numbers. However, for consistency and to avoid confusion, it is recommended to always use the full national number.

Services and Usage

Numbers under the 23 prefix are primarily used by government institutions, businesses, and residential subscribers. They are connected to the PSTN and support traditional voice services, as well as ADSL and fiber-optic internet where available. The network infrastructure is managed by the state-owned Telecommunications Authority of Kiribati (TAK), which operates both fixed and mobile services.

For callers from abroad, it is essential to check with your service provider for international dialing rates to Kiribati. Calls to geographic numbers are typically charged at standard international rates, which may vary depending on the destination and the carrier.
