The Principal, Responsible Official and each employee assigned to use e-Services products must register individually to create and have access to a secure mailbox. The registration process is a one-time automated process where the user selects a username, password and PIN that will be needed to log onto e-Services. It can be started before, during or after the IVES application is submitted but takes two weeks to complete. After verifying the information provided, the IRS will mail a registration notice containing a confirmation number to the registrant’s last known address of record. See the e-Services registration information for more details. The main IRS.gov IVES site
