How is a NetID different from any other Cornell ID number I have now?
NetIDs are the official identifier for the Cornell electronic network and its online services. If you have signed up for e-mail forwarding, for example, the NetID is the identifier in the Cornell e-mail address that precedes the “@cornell.edu.” This ID is different from the six- or seven-digit personal identification number that has been used for accessing various services in the past. Because the NetID is combined with a password, it affords you much greater security.
