|Financial Databases and Research|
Some months ago I considered the CUSIP (Committee on Uniform Security Identification Procedures) identifier to be a fairly good identifier because it is a unique code for companies and has existed since it's introduction in 1968. Unfortunately only CUSIP 6 is more often available in databases as a search option. The extended identifier CUSIP 8 or 9 occurs a lot less as a search option and often can not be downloaded.
Example for the company Teleconnect:
CUSIP 6: 879292
The Cusip 8 is a stock/security identifier. CUSIP 9 has the extra check digit (which can also
be calculated) which is needed to be able to check whether the CUSIP identifier format is correct. For more information on CUSIP etc, you can look in the updated files below:
It is possible to find the security type for some companies using CUSIP 6 if you use the
CUSIP Master File through the Wharton portal. Once you have the security type indicator, the check digit can be calculated. Depending on which part database of the Master File is used you can either download the CUSIP 8 or the security type indicator as a separate data item.
It is not possible to use a CUSIP identifier to directly find information on that security
through Datastream. In Datastream you should search for securities by name, ISIN, DS codes (or mnemonics) and Sedol codes. Using the WorldScope database through datastream you can, however, use the Cusip 9 to find codes like ISIN or a DS code. This search option can of course only be used for those companies which are available through WorldScope. For many companies you will probably not be able to get an alternative code this way.
Searching for a code in WorldScope using a CUSIP 9 code goes as follows:
The result for a search on WS:879292100 should be: Teleconnect and US8792921004.
