The ninth banknote series was launched in April 2016 to gradually replace the eighth series. The final denomination, the 100-franc note, was issued on 12 September 2019. All banknotes from the eighth banknote series remain valid until further notice.
Banknotes from the sixth and eighth series can be exchanged in person at the SNB counters in Berne and Zurich and at the agencies, or they can be sent to the SNB by post. Further information is available in the Instruction sheet on exchanging recalled banknotes.
