What is an Oracle CSI Number?

The short answer: an Oracle CSI, or CSI number, is a Customer Support Identifier. It is the unique number Oracle assigns to the licenses you buy under one license agreement or Ordering Document. Oracle uses it to know which licenses are eligible for support and to invoice your support renewals. You must register it in My Oracle Support and quote it whenever you raise a support service request.

The questions we hear most are: what is the full form of CSI in Oracle, what is a CSI contract, why does the CSI matter, and why do we have so many CSI numbers in our Oracle portfolio. The sections below answer each one.

What is a CSI?

• A CSI is a unique number assigned to Oracle licenses that are purchased in a single license agreement or Ordering Document.
• The CSI identifies the licenses that are eligible for support.

How Oracle assigns and uses a CSI

• A CSI number is assigned after you sign an Oracle Ordering Document.
• Products from different license sets that were bought on the same purchase order share the same CSI.
• Oracle Support first sends the CSI to the customer. This happens after you have signed the Ordering Document and Oracle has invoiced the licenses.
• For cloud contracts, the number is in your contract document and in the Infrastructure Classic Console or Applications Console.
• The CSI has to be registered in My Oracle Support.
• You have to give the CSI to Oracle whenever you raise a support service request.

Why do you have so many CSI numbers?

Each Ordering Document gets its own CSI. A company that has bought from Oracle over many years, through acquisitions or through several contracts, ends up with many numbers. Each one is a separate support line with its own renewal.

What a CSI means for your support bill

Because Oracle invoices support by CSI, the rules on support apply CSI by CSI, and two of them cost the most.

• Dropping part of a CSI. Under Oracle’s support policies, a product and its options are supported together, and ending support on some licences in an order makes Oracle reprice the licences that remain. The saving can disappear.
• Letting a CSI lapse. Coming back to support later costs a reinstatement fee of 150% of the last annual fee for the time you were away.

So before you cancel or let a support line lapse, check which licences share its CSI. Our page on Oracle support costs explains how the bill is built.

Oracle CSI numbers and Oracle licensing

The CSI plays a real part in licensing and compliance because Oracle raises its support renewal invoices by CSI. That makes the list of your CSIs the starting point for any support cost review. We analyze CSIs during our Oracle audit defense work, our baseline license reviews and our ULA exit advisory.

For what support costs and how it is calculated, see Oracle licensing costs. To understand how licenses are grouped in an order, read Oracle contracts.

Questions we are asked about the Oracle CSI number

What is the full form of CSI in Oracle?

Customer Support Identifier.

Where do I find my Oracle CSI number?

Oracle Support sends it after you sign the Ordering Document and Oracle invoices the licenses. For cloud contracts it is in the contract document and in the console. Once the CSI is registered in My Oracle Support, you can use it when you raise a service request.

Can we cancel support on one CSI?

You can, but check what the CSI covers first. Ending support on only some licences in an order makes Oracle reprice the ones that remain, and a product and its options have to be supported together.

Is a CSI number the same as a license?

No. A CSI groups the licenses bought under one Ordering Document and links them to support. One CSI can cover many products.
