KZ — Kazakhstan

Kazakhstan is the world's largest landlocked country, spanning Central Asia from the Caspian Sea to China. Astana (formerly Nur-Sultan, renamed back in 2022) is the capital, while Almaty is the largest city and economic center. Kazakhstan is rich in oil, gas, and minerals. The Kazakhstani Tenge (KZT) uses the ₸ symbol. For developers, the KZ country code maps to kk-KZ for Kazakh and ru-KZ for Russian. The .kz domain and the +7 dialing code (shared with Russia) serve Kazakhstan. The +7 sharing with Russia complicates phone-based country detection — Kazakhstan uses +7 6xx and +7 7xx area codes. Kazakhstan is transitioning from Cyrillic to Latin script for the Kazakh language, an ongoing process that affects text processing. The recent capital renaming (Astana → Nur-Sultan → Astana again) illustrates how frequent name changes can occur. Kazakhstan's massive territory across five time zones and growing tech sector make proper localization important.
