}ISO 3166 Standard
ISO 3166 is the international standard for country codes. The alpha-2 code (NL) is the most commonly used format for domain names, language tags, and internationalization. The alpha-3 code (NLD) is used in shipping, banking, and official documents. The numeric code (528) is language-independent and useful for systems with character encoding limitations.
