UA — Ukraine

Ukraine is the largest country entirely within Europe, located in Eastern Europe. Kyiv, the capital, is one of Europe's oldest cities. Ukraine has a strong technical education system and one of the world's largest IT outsourcing sectors. The Ukrainian Hryvnia (UAH) uses the ₴ symbol. For developers, the UA country code maps to the uk-UA locale for Ukrainian (note: the language code is 'uk', not 'ua'). The .ua domain and +380 calling code serve Ukraine. A common developer error is using 'ua' as the language code — the correct ISO 639-1 code for Ukrainian is 'uk'. Ukrainian uses Cyrillic script with some letters distinct from Russian Cyrillic (ґ, є, і, ї). Ukraine has one of the world's largest developer communities and is a major source of IT talent. The capital city's spelling was officially changed from 'Kiev' to 'Kyiv' in English, requiring database updates. Sanctions and conflict-related compliance checks involving UA are important for financial and export-control applications.
