Every American security, from stocks to bonds to mutual funds and other investments, carries its own unique CUSIP number. CUSIP stands for Committee on Uniform Security Identification Procedures. A CUSIP number is a way of identifying a particular security, like a stock symbol. Whereas stock symbols can change, a security's CUSIP number is attached to it for life. Bonds can be easier to identify via CUSIP numbers because they don't generally carry trading symbols, like stocks. A bond's CUSIP is also a shorter way to identify a bond, rather than using descriptors such as name, rate and maturity date.

Look in financial publications, such as the Mergent Bond Record. The more identifying information you have about a bond, the more likely you are able to find the CUSIP number. Since there are so many CUSIP numbers, many publications only list bonds from common or popular issuers.

Ask a financial adviser. Financial services firms have access to securities databases that can make a CUSIP search more fruitful, particularly for lesser-known issuers.

Many issuers have tens or even hundreds of similar bond issues, and the slightest difference in detail could lead to an incorrect CUSIP number.
