The Reserve Bank on Thursday extended the deadline for exchanging pre-2005 currency notes of various denominations, including of Rs.500 and Rs.1,000, by six months till December 31, 2015.
The earlier deadline was expiring on June 30.
"The Reserve Bank of India has extended the date for the public to exchange their pre-2005 banknotes till December 31, 2015," it said in a press release.
RBI had, in December 2014, set the last date for public to exchange these notes as June end.
It is easy to identify pre-2005 notes. The currency notes issued before 2005 do not have the year of printing on the reverse side. In notes issued post 2005, the year of printing is visible at the bottom on the reverse.
Soliciting cooperation from public in withdrawing these banknotes from circulation, RBI urged them to "deposit the old design notes in their bank accounts or exchange them at a bank branch convenient to them."
The central bank said that the notes can be exchanged for their full value. RBI also clarified that all pre-2005 notes continue to remain legal tender.
The rationale behind the move to withdraw banknotes printed prior to 2005 is to remove them from the market because they have fewer security features compared with banknotes printed after 2005.
Explaining the move, RBI said the banknotes in Mahatma Gandhi series have now been in circulation for a decade.
A majority of old banknotes have been withdrawn through bank branches.
Over 164 crore pre-2005 currency notes of various denominations, including of Rs 1,000 were shredded in regional offices of Reserve Bank in 13-month period ending January. The face value of the shredded currency notes was around Rs.21,750 crore.
As many as 86.87 crore pieces of Rs.100, 56.19 crore pieces of Rs.500 and 21.75 crore pieces of Rs.1,000 were shredded.
