CUSIP is an abbreviation for Committee on Uniform Securities Identification Procedures of the American Bankers Association. CUSIP numbers are designated and assigned by the CUSIP service bureau, operated by Standard and Poor’s. The CUSIP, or CUSIP number, is an alphanumeric identifier, comprising nine characters, for every class of traded financial instrument in the United States, including all US Government, municipal and corporate securities and syndicated loans. The CUSIP number is used to facilitate back-office clearing, matching, and settlement of securities. The first six characters of the CUSIP identify the issuer, the next two characters identify the issue itself, and the ninth digit is termed a check digit. Various regulatory agencies require that a security have a CUSIP identifier, and it has become common for any security to receive a CUSIP at issue. International securities can have a CUSIP international number (CINS), Sedol, or ISIN for standardized identification.
