If it is before April 1 and you need to change your shipping information, log in to the attendee service center (2024) using the information located on your confirmation email. From there, you can edit your information as needed. Please note that if your address is greyed out you will need to enter your address in the Address Verification field to update. Make sure you go all the way through the registration process so that it saves the update. If you do not add on any additional items, the system will not charge you again.
If it is after April 1, please contact our registration team at registration@acen.org for assistance.
