Nsc certificate

NSC can be encashed at other branches as well. After presenting the certificate (with duplicate copy and identification documents) at the other branch, they will send the same to the registered branch. After verifying the same, the registered branch will remit the maturity amount. But it will take approximately 1-1.5 month of time.

Rule 17 of NSC Rules, 1989 and 2011 (for VIII and IX Issue)

Place of encashment:

Provided that a certificate may be encashed at any other post office if the officer-in-charge of that post office is satisfied on verification from the office of its registration that the person presenting the certificate for encashment is entitled thereto.
