The following has been stated
Facility for Exchange of Notes and Coins at Bank Branches
All bank branches in all parts of the country are mandated to provide following customer services, more actively and vigorously to the members of public so that there is no need for them to approach RBI Regional Offices for this purpose:
(i) Issuing fresh / good quality notes and coins of all denominations,
(ii) Exchanging soiled / mutilated / imperfect notes,
and
(iii) Accepting coins and notes either for transactions or exchange.
(b) Banks shall ensure that all their branches provide facility for exchange of notes and coins not only to their customers but also others. Small Finance Banks (up to two years from the commencement of their banking business) and Payment Banks may exchange mutilated and imperfect notes at their option.

(e) The availability of the above-mentioned facilities at the bank branches shall be given wide publicity for information of the public at large.
