A Cisco ID number (i.e. CSCO0000009) is used to identify a candidate in the Cisco Certifications program. This number will appear on a candidate's exam score report and on a candidate's certificate once a certification is achieved.
After completing the first Cisco exam, the candidate will be issued a Cisco ID number that should be used to register for all future Cisco exams to avoid delay in receiving proper credit. The Cisco ID number is also used to login to the Certifications Tracking System to access certification and testing information. To login to the Certifications Tracking System go to www.cisco.com/go/certifications/login.
