The apex bank's spokesman, Osita Nwanisobi, revealed this on Friday, saying that deposits of more than N500,000 were not permitted.
The news comes as Nigerians are furious over the rejection of currencies that President Muhammadu Buhari proclaimed to be worthless.
Buhari requested that Nigerians bring their used N500 and N1000 currencies to the CBN in his national broadcast.
Nigerians flocked to the headquarters of the apex bank to deposit their old money.
The throng was directed to commercial banks as the bank personnel fought to keep them under control, but they were rebuffed.
