What are ISO 3166 Country Codes?

ISO 3166 is the international standard for country codes published by the International Organization for Standardization (ISO). It defines three different formats:

• Alpha-2 (e.g., US, GB, DE): The most widely used two-letter codes, often seen in domain names, shipping, and general abbreviations.
• Alpha-3 (e.g., USA, GBR, DEU): Three-letter codes that are generally more intuitive and less ambiguous than Alpha-2 codes. Often used in government and international organizations.
• Numeric (e.g., 840, 826, 276): Three-digit codes developed by the United Nations Statistics Division. Useful in systems where using Latin letters might be problematic.

This page provides all three formats (ISO 3166-1 Alpha-2, Alpha-3, and Numeric) for your convenience.
