Committee on Uniform Security Identification Procedures

CUSIP® Securities Identification

CUSIP® is the universally recognized identifier for financial instruments.  CUSIP® identifiers cover a wide range of global financial instruments, including extensive equity and debt issues, derivatives, syndicated loans and U.S. listed equity options.

CUSIP® -  Based Identifiers

CUSIP - based identifiers support the accurate and efficient clearance and settlement of securities, as well as processing associated with income payments made during the lifecycle of an issue. They enable:

  • Holders, analysts and brokers to rapidly identify and access issue-specific data
  • Custodians and sub-custodians to easily communicate on securities transactions
  • Depositories to accurately manage transactions and examine historical data

These identifiers include:

  • CUSIP® - Universally recognized identifier for financial instruments (CUSIPs are 9-character identifiers that capture an issue's important differentiating characteristics within a common structure)
  • CINS - CUSIP® International Numbering System
  • CUSIP-based ISIN - Participation in the assignment of CUSIP-based International Securities Identification Numbers
  • CABRE - CUSIP Avox Business Reference Entity Identifier - a new standard code designed to address the market need for an acceptable universal identification system.  This identifier identifies Issuers, Obligors and Counterparties on a global basis.
