BY — Belarus

Belarus is a landlocked Eastern European country bordered by Russia, Ukraine, Poland, Lithuania, and Latvia. Minsk, the capital, is the largest city and economic center. Belarus is notable for its Soviet-era architectural heritage and extensive forest cover. The Belarusian Ruble (BYN) replaced the old ruble (BYR) in 2016 through redenomination. For developers, the BY country code maps to be-BY for Belarusian and ru-BY for Russian — both languages are official and use Cyrillic script. The .by domain and +375 calling code serve Belarus. The 2016 currency redenomination from BYR to BYN (removing four zeros) requires handling both codes in historical data. Belarus has a strong IT sector — Minsk's Hi-Tech Park hosted the creation of companies like EPAM Systems and Viber. Sanctions have complicated international tech operations involving Belarus, making compliance checks on BY country codes relevant for financial and export control applications.
