About This Item
TS ISO 3166-3 defines the basic rules for implementing and maintaining a coding system for formerly used country names. It addresses the representation of historical country names within the ISO 3166 family, helping systems identify countries that are no longer current and keep related records consistent over time.
What the code is used for
In general technical use, codes for former country names help databases, archives, library systems, and document management workflows distinguish obsolete country names from current ones. Because country names can change through renaming, dissolution, or state reorganisation, it is important to preserve an unambiguous link to the historical entity being referenced. ISO 3166-3 serves this purpose by addressing the code structure used for country names deleted from ISO 3166.
Why maintenance matters
The standard focuses on the implementation and maintenance of codes for non-current country names. In practice, that supports historical record retrieval, data matching, and linking legacy records to later country names. It provides a reference framework for managing the difference between current country names and their historical predecessors in a controlled way.
- Focuses on codes for non-current country names.
- Covers country names deleted from ISO 3166.
- Supports consistent classification of records and documents.
- Helps reduce confusion between old and current country names.
