Cusip Service Bureau
What is a Cusip from
CUSIP stands for Committee on Uniform Securities
Identification Procedures. Formed in 1962, this committee developed
a system (implemented in 1967) that identifies
specifically U.S. and Canadian registered stocks, and U.S. government
consists of a combination of nine characters, both letters
and numbers, which act as a sort of DNA for the security - uniquely
identifying the company or issuer and the type of security.
The first six characters identify the issuer and are assigned
in an alphabetical fashion; the seventh and eighth characters
(which can be alphabetical or numerical) identify the type of
issue; and the last digit is used as a check digit.
CUSIP Service Bureau is operated by
Standard & Poor's
on behalf of the American Bankers Association (ABA).
When setting out to develop the CUSIP system of identification,
the ABA basically had two main criteria it was trying to meet.
First, it wanted the identification to contain the fewest number
of characters possible and to be linked to an alphabetical sequence
of issuer names. Secondly, it recognized that the system should
be adequate given the current operating requirements while having
the flexibility to adapt to any future needs or changes in the
operating systems. For more information on the CUSIP system,
