An ISIN is a unique 12 digit alphanumeric code given to the securities such as shares, preference
shares, debentures, bonds, etc. when the security is admitted in the depository system. The first
two digits of the ISIN code indicate country of registration for the security.

For instance:

NP=Country Code for Nepal

002=Issuer Code
