What is a CUSIP?

CUSIP is an acronym that refers to Committee on Uniform Security Identification Procedures and the nine-digit, alphanumeric CUSIP numbers that are used to identify securities, including municipal bonds. A CUSIP number, similar to a serial number, is assigned to each maturity of a municipal security issue. The first six characters are known as the base, or CUSIP-6, and uniquely identify the bond issuer. The 7th and 8th digit identify the exact bond issue and the 9th digit is an automatically generated "check digit."
