🏛️ CUSIP Structure Explained

A CUSIP (Committee on Uniform Securities Identification Procedures) number is a 9-character identifier for North American securities. The first 6 characters identify the issuer, the next 2 identify the specific security, and the last is a check digit. Microsoft's CUSIP 594918104 demonstrates this structure. CUSIPs are mandatory for all securities traded in the US and Canada.
