RU — Russia

Russia is the largest country in the world by area, spanning eleven time zones across Europe and Asia. Moscow, the capital, is one of the world's largest cities. Russia has significant natural resources and a strong technical education system. The Russian Ruble (RUB) uses the ₽ symbol. For developers, the RU country code maps to the ru-RU locale for Russian, one of the most important Cyrillic-script locales. The .ru domain has millions of registrations (plus .рф for the Cyrillic domain). The +7 dialing code is shared with Kazakhstan. Russian Cyrillic text handling, including proper sorting, case conversion, and transliteration, is fundamental for many applications. Russia's eleven time zones (from UTC+2 to UTC+12) create complex timezone handling requirements. International sanctions have significantly affected Russia's tech ecosystem, requiring developers to implement sanctions compliance checks involving the RU country code. Despite sanctions, Russia has a large domestic tech ecosystem and developer community.
