The NetID is the unique electronic identifier in which the password permits secure access to non-public Cornell resources and information.

NetIDs are unique and permanent. The same NetID is never reassigned to more than one individual; if you leave the university and return at a later time, the original NetID is reactivated for your use.

In combination with the password, the NetID enables access to non-public resources and information. For example, every student must log in with their NetID and password to access grades and other information in Student Center. It also serves as the unique portion of a Cornell email address in the form NetID@cornell.edu.

Sponsored NetIDs are intended for use with contractors or other individuals who are not directly affiliated with Cornell, but have a business purpose for needing access to Cornell services or systems.

Graduates of the Hotel School's professional development program may be issued a NetID at the school's discretion. NetIDs are issued twice a year after the conclusion of the January and summer programs. These individuals are known as "associates" in the Identity Management system.

Other ID Types

Other types of ID are also in use at Cornell:

• GuestID, which allows users who are not eligible for a NetID to access certain services.
• ApplicantID, which is assigned to Cornell applicants.
• WCMC CWID, the ID for Weill Cornell Medicine.

In addition, visitors from institutions that participate in eduroam can sign in to Cornell's secure eduroam Wi-Fi network using their home institution login and password.
