A specific nine digit number which identifies all stock and registered bonds, using the Committee on Uniform Securities Identification Procedures (CUSIP). This number also will be listed on trade confirmations.

The CUSIP (Committee on Uniform Security Identification) assigns the first nine digits/characters of a CUSIP. Digits/characters 1-6 identify the issuer and digits/characters 7-9 identify the issue. The last three digits are applied by the NSCC (National Securities Clearing Corporation) to distinguish between NYSE, AMEX, and FINRA issues.
