LI — Liechtenstein

Liechtenstein is a tiny Alpine principality between Switzerland and Austria, one of the world's smallest countries but with one of the highest GDP per capita. Vaduz, the capital, is overlooked by the Prince's medieval castle. Liechtenstein uses the Swiss Franc (CHF) through a customs union with Switzerland. For developers, the LI country code maps to the de-LI locale for Liechtenstein German. The .li domain has been popular for domain hacking (names ending in 'li'). The +423 dialing code serves this microstate. Liechtenstein's use of the Swiss Franc without being Switzerland means it shares CHF currency code handling but has distinct regulatory requirements. The principality is a major financial center relative to its size, with banking and financial services being key industries. Liechtenstein is part of the EEA (but not the EU), creating a nuanced regulatory position. The .li domain's popularity for domain hacking gives it more registrations than the tiny population would suggest.
