A CUSIP is a number assigned to a registered security such as a stock, bond, or mutual fund so that the security can be uniquely identified.
What Is a CUSIP? Meaning & History
The Committee on Uniform Securities Identification Procedures (CUSIP) assigns a unique number to individual financial instruments, so that they can be readily and correctly identified. CUSIP numbers are assigned to U.S. and Canadian stocks, commercial paper, mutual funds, corporate bonds, and U.S. government and municipal bonds.
The CUSIP is made up of nine letters and numbers. This system was established in 1964 and implemented in 1967. FactSet Research Systems, Inc. manages CUSIPs on behalf of the American Bankers Association (ABA). There are more than 10 million CUSIP numbers for U.S. and Canadian securities. CUSIPs help effectively facilitate trades and settlements of securities by providing unique identifiers.
How CUSIPs are Assigned
CUSIPs are assigned by the Committee on Uniform Securities Identification Procedures when a financial security registers as a financial instrument on an exchange. CUSIPs are unique identifiers, so there is no duplicate in the system. Each character in the CUSIP has a meaning.
The first six characters identify the issuer and get alphabetically assigned. The following two characters, the seventh and eighth characters, identify the type of security, with the last digit serving as a check digit.
What Gets a CUSIP Number
CUSIPs serve a wide range of U.S. and Canadian securities. You will find a CUSIP assigned for:
Stocks
Government bonds
Municipal bonds
Mutual funds
Commercial paper
CUSIP Number Purpose & Uses
CUSIPs are used to settle and clear transactions properly. While most investors don't need to know the CUSIP number of a security they are buying or selling because they will use the ticker symbol, brokerage and clearing firms use them to ensure the transaction is recorded correctly.
The exception is regarding bonds. Investors should identify bonds with a CUSIP number to prevent confusion regarding bond purchases and sales. The reason is that one entity might have multiple bonds issued for different durations or interest rates.
CUSIP vs. Tickers
Both CUSIPs and ticker symbols are used to identify securities traded on public exchanges. The stock ticker symbol is an alphabetic representation that dates back to the 1800s when the New York Stock Exchange began. The symbols send trade and price information via teletype, referred to as a ticker. This is why they are called ticker symbols. CUSIPs were established in the 1960s and are better suited for computers to track trades.
The CUSIP is operated by Factset Research Systems Inc. Ticker symbols are registered by the New York and American stock exchanges.
Tip: Most investors only need the stock symbol for investment purposes. If you need the CUSIP, check the company's filed documents or website to find it.
