A Network ID (or NetID) is a personal, unique identifier assigned to you. It consists of your initials followed by one or more numbers. You use it, along with a password, to obtain secure access to online services at Cornell.
Activate Your NetID and Email
Beginning April 3, as soon as the university processes your enrollment deposit, you will receive an email (at your admissions email address) that your NetID was created and what to do next.
- Once you receive that email, you will log in with your ApplicantID and password to retrieve your NetID Activation Code.
- Next, you will use this code to activate your NetID and email.
You should activate your NetID immediately. As a new student, you will set up your email account when you activate your NetID. Your email address will look something like this—email@example.com—where "ewe1" is your Cornell NetID.
Once you activate your NetID, your ApplicantID will be disabled, and you will use your NetID to authenticate to Cornell services. NetIDs are permanent, and carry both additional privileges and additional responsibilities.
Your Email Options
Email service for students at Cornell is provided through Cmail (Google Apps Education Edition). Along with email, Cmail includes calendar, collaboration, and other tools. Learn more about Cmail.
You can choose Cmail and/or provide a valid, alternate email address where email sent to your NetID@cornell.edu will be directed. This will ensure that you don't miss important university communications.
Regardless of which email option you choose, you can still use the collaboration services offered through Cmail.
Frequently Asked Questions
What is an ApplicantID?
An ApplicantID or AppID is a personal, unique identifier assigned to you. It consists of "app" plus the year for which you are applying, followed by a dash, followed by your initials, followed by one or more numbers. For example, if your name were "Eugene Walter Ewings", your Applicant ID might be app15-ewe2. New undergraduates are assigned an AppID during the admissions process. You will need your ApplicantID and password to log in and retrieve your NetID activation code.
Help! I forgot my ApplicantID or my ApplicantID password. What do I do?
If you forget your ApplicantID and/or password, or never received one, start here.
What should I do if I forget my NetID password?
Passwords are kept in an encrypted database, and cannot be looked up by anyone. If you set up your password's security questions in advance, you can go to the Manage Your NetID web page to set a new password yourself.
If you’ve lost your NetID password, and you did not set up your password’s security questions, you will need to request a new activation code so that you can reset your password. To make this request, contact the IT Service Desk – you must visit in person, schedule a video chat (via WebEx), or mail or fax your request to that office. You will need to provide proof of identity – your Cornell ID card or your valid government-issued photo ID card (such as a driver’s license or passport), or a photocopy of one of these.
Is it okay to let my family or close friends use my NetID and password?
No. NetIDs are for students' exclusive personal use. It is a violation of university policy to share NetIDs and passwords with anyone, including family members. If someone knows a student's NetID and password, he or she can look up and/or change personal and confidential information and violate federal privacy laws through the student's account.
