Security Identifiers Screens

Bonds, Stocks and Financial Instruments, usually have one or more identifier codes, issued by various clearing houses or other agencies. The purpose of these identifiers is to prevent confusion when discussing a particular security, particularly a bond (because a company will usually only have one class of stock, but can have many different bond issues). This is a list of what the various securities codes stand for, who issues them, and what their structure is.


offers an on-line global analytical system that is useful for institutions buying or selling fixed income securities, equities, or foreign exchange.

CUSIP      (More information on CUSIP)

Stands for Committee on Uniform Securities Identification Procedures. Run by S&P, they assign a nine digit code to stocks and bonds. The first six digits identify the issuer. The next two digits represent the security that was issued, and the final digit is a check digit (uses modulus 10 double add double). First digit is always a number. This identifier is used for Canadian and U.S. securities only: other countries use CIN.


Not used any more; replaced by the Common Code on January 1, 1991.


International Securities Identification Number. This is a twelve digit code developed by the International Standards Organization that represents a security. The first two letters always represent the country code, and the ISO standards are used. Basically, these are the same two letters as used in internet addresses (but GB, not UK is used for Great Britain). The next nine characters use some other code usually, such as CUSIP in the United States, SEDOL in England, etc. Leading spaces are padded with 0. The final digit is the check digit, also computed with modulus 10 double add double, but it's different from the method used in CUSIPs.


ISIDPlus covers all major national and international numbering systems,


Reuter Identification Code. Used on the Reuters Terminal to pull up a particular security. It's a rather ugly looking thing with an equals sign in it somewhere. If the equal sign is that the end, that is a master RIC, whereas a RIC that follows with an equals sign and then some additional letters means that that is the price quoted by someone, symbolized by the letters following the equals sign.


Stock Exchange Daily Official List. British securities identification code. Has a built in check digit system.


Standard Industrial Code. Tells what line of business a firm is in, does not symbolize a security.


Security Identification Code Conference. Used in Japan, usually four digits. Sort of like a ticker in Japan.

Identifier for Swiss securities. No check digit system.
