Unrivaled Experience

Our extensive focus on standardization over the past 50 years has helped us earn the reputation for being the trusted originator of quality identifiers and descriptive data that are interoperable among regulators, banks, vendors, exchanges and depositories.

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 and 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.

CUSIP Global Services is managed on behalf of the American Bankers Association (ABA) by S&P Global Market Intelligence, with a Board of Trustees that represents the voices of leading financial institutions. Read more about our history here.
