Who do I contact if I have general questions?

For general questions about ISIN eligibility requests, contact CDS Onboarding at After a request has been submitted or saved as a draft, you will need to provide the ISIN eligibility request number.

How do I complete the ISIN Eligibility screens?

Please click on "Create a new eligibility request" and refer to the Help for additional details. Please note that the "Security Number" is the full ISIN without any spaces. For assistance with the Issuance Type, please refer to the Eligibility Category Descriptions. Please note that the "Issuance Type" references only the securities which are settling through CDS.


When can I file my eligibility request?

Once final supporting documentation and closing/effective dates are available, the eligibility request can be submitted. Eligibility requests submitted less than 2 business days prior to closing/effective date will be subject to a tiered late fee schedule.

Example: For a closing date on Wednesday, the eligibility request should be submitted prior to noon Eastern Standard Time on Monday to avoid late fees.

Why do I need to file an eligibility request if I have already filed an ISIN Issuance request and received an ISIN?

The ISIN issuance application only provides the ISIN and CUSIP which are the security identifiers. If the securities are to be settled, deposited or closed through CDS, a separate ISIN Eligibility request will be required in order to make the ISIN/CUSIP eligible for trade clearing and settlement in the depository.

How much does it cost to request Eligibility?

Please refer to the fee schedule at for full listing of fees. There are up to 3 potential fees involved in processing Eligibility requests:

  1. Non refundable eligibility fee is applicable to all requests (Code 6236)

How long will it take to process my request?

How can I check the status of my request?

If a valid email address was provided and the payment was processed successfully, a confirmation email is sent immediately. You can check the status of your request at any time by clicking the "View an existing eligibility request" link on the ISIN Issuance and Eligibility page. You will need to provide your ISIN eligibility request number (provided on the email notification from CDS) and requestor email address on file with the request.

Can I save a request in progress and return to it later?

Yes, you can save your request as a draft. Your request will remain accessible for five calendar days at which time it will be purged from the system. During that time, you may edit or update your request at any time until you submit the request. The five days restarts every time you re-save your request. Once the request has been submitted, you will not be able to change it.

How many items can I add to an ISIN Eligibility request?

The application will accept 1 eligibility application per ISIN.
