Greenland

Greenland uses the ISO 3166-1 codes GL (alpha-2) and GRL (alpha-3) to identify the country in international systems, alongside the calling code +299 for direct dialing. Its country-code top-level domain (ccTLD) is .gl, used for local web addresses. The official currency is the Danish krone (DKK), reflecting its status as an autonomous territory within the Kingdom of Denmark. In practice, these identifiers are essential for international telephone calls, domain registration, and financial transactions or business documentation, ensuring accurate routing and compliance across global telecommunications, internet infrastructure, and economic operations in the Americas region.
