Convert CUSIP to ISIN

A CUSIP is a 9-character alphanumeric code which identifies a North American financial security.

A CUSIP consists of three parts:
• A six-character issuer code
• A two-character issue number
• A single check digit.

For example: 780259206 (Royal Dutch Shell-A)

On this page, you can select a country and enter a CUSIP. If the corresponding ISIN is present in the database, the ISIN will be shown. If it is not present in the database, a correct ISIN will be calculated for you, if possible.
Note that the result can be a non-existing ISIN, since it is being calculated!
