Multiple credible sources directly corroborate the statement. Specifically, a 2020 article from CoinsWeekly states 'The Iranian Parliament has voted to implement a programme... which will result in removing four digits or zero's'. Additionally, a more recent article from Reuters confirms that 'Iran has gained parliamentary approval for a monetary overhaul to remove four zeros from its national currency'. The evidence consistently shows a progression from a government plan in 2019 to full parliamentary approval.
