The CUSIP Service Bureau, which is operated by Standard & Poor’s for the American Bankers Association, exists for the primary purpose of uniquely identifying issuers and issues of financial instruments within a standard framework, and disseminating this data to the financial marketplace via various media. The CUSIP Master Files provide CUSIP numbers, standardized descriptions and additional data attributes for over 5 million corporate, municipal and government securities offered in North America. CUSIP numbers and standardized descriptions are used by virtually all sectors of the financial industry, and are critical for the accurate and efficient clearance and settlement of securities and other financial instruments as well as back-office processing. The CUSIP number consists of nine characters: a base number of six characters known as the issuer number, (the 4th, 5th and/or 6th position may be alpha or numeric) and a two character suffix (either numeric or alphabetic or both) known as the issue number. The ninth character is a check digit.
