ISO 3166 — Country codes (subject to professional review)
ISO 3166 standardises internationally used country codes and is not a management system like the other standards on this page. Please check whether a different standard was intended. Pending professional clarification, this entry is presented neutrally in the context of country codes and master data quality.
What does the standard cover?
The standard defines two- and three-letter country codes and codes for subdivisions, used in master data, address fields and international data exchange formats. For businesses, it is particularly relevant to master data quality, for example when maintaining consistent, standard-compliant country fields in ERP or CRM systems.
Who is the standard relevant to?
- Companies with international master data seeking consistent country codes
- IT and data managers seeking better data quality in ERP and CRM systems
- Enquirers who need a management system rather than a data standard
