ID cards are the property of Yale University and must be returned to the ID Center upon termination of enrollment, employment or affiliation. In such situations, the Registrar/Dean or Business Manager should promptly contact Access Control (432.open@yale.edu for Central Campus or 785.open@yale.edu for Medical School Campus) to request deactivation of the ID card. The card should then be returned to the Central or Medical School ID Center for processing and disposal.
