The Center Wide ID, (or “CWID,” pronounced “seaweed”), is a unique identifier consisting of a seven character username assigned to all faculty, staff, and students. This ID is used to log into most major WCM and NewYork-Presbyterian computing systems. It also constitutes the first section of your WCM email address (

CWIDs usually consist of three initials of the user's name (first-middle-last, or for those with no middle name, two letters from the first name and one from the last) and a four-digit numeric identifier. Faculty or staff who began employment with the institution prior to 1998 may have CWIDs that do not adhere to the current convention.

Only one CWID is assigned per person—the account associated with a CWID is deactivated when an individual leaves the institution, but it is never reassigned to someone else. The same CWID is used at both Weill Cornell Medicine and NewYork-Presbyterian Hospital, and follows a user if they change institutions.

Service Requirements

With few exceptions, all faculty, staff, and students automatically receive CWIDs. The following users need to have a CWID manually created at the request of their Department Administrator/Designee, or Division Administrator:

  • Vendors
  • Contractors
  • Affiliates
  • Volunteers
  • WCPN Office Staff
  • Academics who are not full-time WCM faculty

While your CWID is automatically assigned, users must separately request access to most services where a CWID is used (e.g., email, calendar, EpicCare, etc.). Many of these requests can be made by contacting the ITS Service Desk. However, you can request eFax by using our Account Services form.
