ISIN Issuance and ISIN Eligibility Services

The ISIN Issuance service provides entities involved with the issuance of new marketable securities with the ability to request and purchase ISIN and CUSIP® identifiers online.

The ISIN Eligibility service enables entities to request eligibility assessment and acceptance of marketable securities within CDSX®, the CDS clearing and depository system.

ISIN Issuance and Eligibility requests are accepted for the following security types:

  • Equity Issues
  • Long Term Debt Issues
  • Medium Term Note Programs
  • Money Market Instruments
  • National Housing Act Securities
  • Strip Bond Packages, Coupon and Residual Components

Both services are required for securities held on deposit with CDS.


ISIN (International Security Identification Number) is an international code that uniquely identifies securities. Every CDSX® eligible security requires an ISIN.

The Association of National Numbering Agencies (ANNA) is committed to the use of standard identifiers to make the financial world a more efficient, safer and more stable environment for investors and the financial institutions that serve them. Securities from more than 120 nations are identified by ISIN numbers. No matter where a security was first issued, an ISIN enables it to be recognized and traded between buyers and sellers virtually anywhere in the world. CDS is the National Numbering Agency (NNA) in Canada that assigns ISIN numbers to each new security issued. For more information about ANNA and Global standards, please visit


CUSIP® (Committee on Uniform Security Identification Procedures) is a standard system of securities identification and securities description that is used in electronically processing and recording securities transactions in North America. A CUSIP® number uniquely identifies a Canadian or American security and its issuer.

As a service bureau to the Canadian financial industry, CDS Solutions coordinates the assignment of ISIN and CUSIP® numbers with Standard & Poor's (S&P).

CUSIP® is a registered trademark of the American Bankers Association.
