We are the trusted originator of quality identifiers and descriptive data.

In July 1964, the New York Clearing House Association approached the American Bankers Association to develop a way to improve operating efficiencies across the industry by developing a standard method of identifying securities. The Committee on Uniform Security Identification Procedures (CUSIP) was created to work on this issue.

This resulted in the establishment of the CUSIP system and, in 1968, the CUSIP Service Bureau was formed to administer the system. Over the years, the organization's core competencies in securities identification and data management, as well as their strong relationships with industry stakeholders positioned it as a catalyst for innovation. As coverage expanded to include new financial instruments and geographies, CGS emerged as the overarching entity for all CUSIP offerings.

We are the trusted originator of quality identifiers and descriptive data.
