Banaba Postal Codes: KI0121 | Gilbert Islands

Key Facts

Banaba, also known as Ocean Island, is an isolated raised coral island that forms part of the Republic of Kiribati. Located within the Gilbert Islands group, Banaba stands as a distinct entity separate from the main Gilbert Islands chain, situated approximately 420 kilometers east of Nauru and about 2,600 kilometers southwest of Hawaii. This small island covers an area of just 6.29 square kilometers and has a population of around 300 people as of recent estimates. Historically significant for its rich phosphate deposits, Banaba was extensively mined during the 20th century, which dramatically altered its landscape and led to the relocation of much of its population to Rabi Island in Fiji. Administratively, Banaba is considered one of the districts of Kiribati, though it has a unique historical and cultural status. The island's rugged terrain, with limestone cliffs rising up to 81 meters above sea level, contrasts sharply with the low-lying atolls typical of the Gilbert Islands. Today, Banaba faces challenges related to environmental rehabilitation and maintaining connections with its diaspora community. For those seeking to access postal services or communicate with this remote location, understanding its specific administrative structure is essential for accurate addressing.
