Sweden uses the Swedish Krona (SEK) as its official currency. The krona is divided into 100 öre, and banknotes are printed in values of 20, 50, 100, 200, 500, and 1,000 kronor. The coin denominations are 1, 2, 5, and 10 kronor. Despite being a part of the EU, Sweden does not use the euro, and older versions of some banknotes and coins are no longer valid. Its best to use Swedish Krona when visiting Sweden, as businesses may factor conversion costs into their prices if paying in a foreign currency like the Euro.
