A search by Committee on Uniform Securities Identification Procedures number allows an investor to find a particular stock or bond, according to the Securities and Exchange Commission. All publicly traded U.S. and Canadian securities have a Cusip number. Cusip provides a similar system for identifying international securities.
A Cusip number has nine digits, according to Cusip Global Services. As of 2015, Cusip numbers uniquely identify more than 26 million investments. Within a Cusip number, six characters identify the issuer, two characters identify the instrument and the ninth character validates the other eight. Several companies and websites allow investors to find securities by Cusip number, including Fidelity Investments, Yahoo Finance and QuantumOnline.com.
