Cornell NetIDs

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 5, once the university processes your admission response and, if applicable, your deposit, you will receive an email (at your admissions email address) that your NetID was created and what to do next.

Graduate School Students

Cornell Tech (NYC), Johnson, Law and Vet Students

  • You will receive a text message with instructions to activate your NetID and Cornell email account.
  • If you do not have a text-enabled cellphone number on record, a postal letter with instructions for activation will be mailed to you.

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——where "ewe1" is your Cornell NetID.


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 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.

Office 365 Email & Calendar

As a graduate or professional student, you have an additional option for your Cornell email—an account on Microsoft's Office 365 service.

Cornell Office 365 accounts for graduate or professional students are intended primarily to be used to perform university business while at Cornell. Guidance about whether a graduate or professional student's work is considered university business should be determined by the department or unit that oversees that work.

For graduate or professional students, Cornell Office 365 accounts provide storage of up to 50GB (gigabyte) and include email, calendar, tasks, and address books. These accounts are in addition to the Cmail account that every student receives, and/or the email account their department or college may provide.

Get started with your Office 365 account.

Frequently Asked Questions

  • What should I do if I forget my 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 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 share my NetID and password with family or friends?

    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.
