For online support and information for the Cisco Connection suite, users must register for the Cisco Connection Online website. When you register, you receive a CCO number which is used to access the online resources. CCO is considered to be the “first line of customer support” for Cisco Systems. The site first began in 1992 as a portal for bug information and technical support.


Before you register for a CCO number, there are a few requirements you must meet. You must use the first and last name of an individual to register. Company and/or group names are not acceptable. Cisco will not let you register more than once. If you are a customer of a Cisco partner or distributor, you must receive advance approval and sponsorship from Cisco before registering for a CCO number.


You must register for the CCO site via the Cisco User Registration page on Cisco's website. When you press “Register,” you must enter all required information, which includes first and last name, address, phone number, a valid email address and the password you will use to access the website. To complete the registration, enter the service contract number, sponsor number or partner service agreement number provided to you by Cisco. If you do not have these numbers, contact a customer support representative at Cisco.

Verify Account

After registering, log in to the email account you used during the registration process. Open the Cisco verification email and click the verification link. Complete the registration process to verify your account. Check your email again for a new message from Cisco. This message contains your CCO number. The number is your username for the CCO site.

User Types

Cisco allows four types of users to register for a CCO number – Cisco Customers, Cisco PICA Customers, Cisco Partners and Premier Resellers. To qualify, you must have a service or support contract with Cisco or have your Cisco equipment serviced by an authorized Cisco partner. The resources available through the CCO site vary based upon each user type.
