What is a CUSIP Number?
A CUSIP (Committee on Uniform Securities Identification Procedures) number is a unique 9-character alphanumeric identifier assigned to financial securities in the United States and Canada. The first six characters identify the issuer, the next two characters identify the specific issue, and the last character is a check digit. For example, Apple Inc.'s common stock has the CUSIP number 037833100. CUSIP numbers are essential for clearing and settlement of trades, regulatory reporting, and accurate identification of securities across different trading platforms and financial institutions.
