Person ID (PID)
What is a PID?
The Person ID Number (PID) is an identification number assigned to all people with a university relationship, as defined by an official university department. This number is designed to give all persons a universal number (PID or Person ID) that is unique to the University of North Carolina at Chapel Hill. The number is nine digits long and replaces all existing card numbers previously used on campus. The PID is the primary record keeping key for all departments within the university and must be used for all communication.
How do I get a PID?
Undergraduates will be notified of their PID when they are sent a letter notifying that they have been accepted.
Graduate Schools will notify prospective students that their application has been received. In that notification, they will be given their PID and told to use it to check the status of their application online. Students already having a PID can have it reactivated when they re-enroll.
Continuing Studies creates PIDs for part-time students.
How do I reactivate my PID?
Student records become inactive when a student fails to register by the end of the drop/add period for the current spring or fall semester. Any student not enrolled in the current semester will receive notice that their Onyen is no longer active. This status will continue until the student re-enrolls.
Note: The issuance of a PID does not indicate that you have or will be admitted to the University of North Carolina at Chapel Hill. Admissions decisions are communicated only in writing and only by the respective admissions office.
EHRA & SHRA Staff
PIDs for EHRA and SHRA staff are created, or update when there is an existing PID for the individual, when the departmental HR Facilitator requests the background check as part of the hiring process for new or returning EHRA & SHRA staff.
Once the hiring process is completed, the PID is active to create Onyen 30 days prior to hiring date. Please note if the hiring action is completed within that 30 day period an One Card cannot be created until the following business day.
