ICR 100
ICR 100 is the International Codes Registry standard for territories and geopolitical entities.
It assigns identifiers to sovereign states, dependencies, disputed territories, special administrative areas, transitional administrations, and historical entities. Each record contains the entity name, code values, status, and effective dates.
