You can then use the verification tool to check or lookup the current status of any CCIE.

You will need a valid cco login and then go here:
https://tools.cisco.com/CCIE/Schedule_Lab/CCIEOnline/CCIEOnline?verify

Enter the information and the Cisco website will validate if the said engineer holds a valid CCIE certification.

It is very simple to check CCIE status of any engineer before hiring.
