International Organization for Standardization
ISO Regions provide a standardized way to divide the world beyond country borders. Defined by the International Organization for Standardization under the ISO 3166-2 standard, this system breaks down every sovereign country into its principal subdivisions, such as states, provinces, cantons, departments, or prefectures.
For travelers who want to explore deeper within individual nations, tracking visits to ISO Regions offers a structured and globally recognised framework. It encourages travel beyond capital cities and major hubs, revealing the cultural, geographic, and regional diversity that defines each country.
