Flint Postal Codes: KI0308 | Line Islands

Key Facts

Flint is a small, uninhabited coral island that forms part of the Line Islands group within the Republic of Kiribati. Located approximately 740 kilometers northwest of Tahiti in the central Pacific Ocean, Flint Island sits at the southeastern end of the Line Islands chain. With a land area of just 3 square kilometers, this remote atoll is one of the most isolated places on Earth. The island features a shallow lagoon surrounded by a narrow coral reef, though it lacks significant vegetation beyond low-lying shrubs and grasses. Historically, Flint Island was discovered by European explorers in the early 19th century and saw limited guano mining activity, but it has never supported a permanent human population due to its extreme isolation and lack of freshwater sources. Today, the island remains an important nesting site for seabirds and is occasionally visited by scientific expeditions studying Pacific island ecosystems. As part of Kiribati's outermost territories, Flint Island represents the kind of remote location where accurate geographical information is essential for navigation, research, and understanding the full extent of the nation's dispersed island groups.
