GR — Greece

Greece is a southeastern European country on the Mediterranean, the cradle of Western civilization, democracy, and the Olympic Games. Athens, the capital, is dominated by the Acropolis and Parthenon. Greece has thousands of islands, many of which are major tourist destinations. The Euro is the currency. For developers, the GR country code maps to the el-GR locale for Greek (Ellinika), which uses the Greek alphabet — a script that is also fundamental to mathematics and science notation. The .gr domain is well-established, and +30 is the dialing code. Greek text requires proper Unicode support for polytonic Greek characters used in scholarly contexts. Greek number formatting uses period for thousands and comma for decimal separator. Greece's AFM (tax identification number) has a specific validation algorithm. The Greek alphabet's dual use in text and mathematical/scientific notation means font and rendering support must be robust. Greece's tourism sector makes localization particularly important for travel and hospitality applications.
