The ISO 4217 code for the Russian ruble is RUB.
RUB is the current three-letter code used for Russia’s national currency, the ruble. The currency is issued by the Central Bank of Russia and is divided into 100 kopeks, although low-value kopek coins have become uncommon in everyday transactions. Its symbol is ₽.
The code RUB became current after Russia’s 1998 redenomination. Before that reform, the ruble used the code RUR. The conversion was 1 RUB for 1,000 old RUR, meaning the change removed three zeros from prices and banknotes while preserving the currency’s name.
That earlier code explains the most common quiz trap: RUR is historically associated with the Russian ruble but is not the current ISO 4217 code. UAH is the code for Ukraine’s hryvnia, while BYN identifies the Belarusian ruble. RUB should therefore be accepted as the single canonical answer for the modern Russian currency. The ruble’s history stretches back centuries, but the present Russian ruble dates from the post-Soviet monetary system established in the early 1990s.
