IS — Iceland

Iceland is a Nordic island nation in the North Atlantic, known for its dramatic volcanic landscapes, geysers, glaciers, and the Northern Lights. Reykjavík, the capital, is the world's northernmost national capital. Iceland runs almost entirely on renewable energy (geothermal and hydroelectric). The Icelandic Króna (ISK) has no subdivision. For developers, the IS country code maps to the is-IS locale for Icelandic. The .is domain has been used for domain hacking, and +354 is the dialing code. Icelandic is notable for its patronymic naming system — people use their father's (or mother's) first name plus '-son' or '-dóttir' instead of family names, which breaks conventional first name/last name form fields. Icelandic phone books are sorted by first name. The Icelandic language preserves Old Norse features and uses special characters (þ, ð, æ) requiring proper Unicode support. ISK amounts have no decimal places. Iceland's unique naming conventions are an important test case for internationalized name handling in forms and databases.
