ISO 3166-1: Alpha-2 and Alpha-3 Codes
ISO 3166-1, the international standard for country codes, provides three sets of codes: alpha-2 (two-letter), alpha-3 (three-letter), and numeric (three-digit). These codes are widely used in various applications, including data exchange, addressing, and identification.
The alpha-2 codes, consisting of two uppercase letters, are the most commonly used for representing countries. For example, the alpha-2 code for the United States is "US", while the alpha-3 code is "USA". The alpha-3 codes provide a more detailed representation, allowing for finer distinctions between countries with similar names.
