Identity Management, NetID Activation Code Incorrect or Expired
An admitted student must claim their NetID, which will serve as their main account for Illinois websites and services. Admitted students receive a UIN (University Identity Number) and an Activation Code (a separate 8-digit number). These are provided to undergraduate students in MyIllini, and to graduate students in their admission letter.
Activation codes are used at the NetID Claim site, which guides incoming students through setting up their accounts: https://netidclaim.illinois.edu/
Detailed instructions for completing the Claim process can be found here: NetID Claim, How to Claim for Students
Activation codes must be used within a year. If you've deferred admission for longer than this, contact the Technology Services IT Service Desk by email at consult@illinois.edu or by phone at 217-244-7000. They will be able to inspect your account and see what you need to do next.
