Hi Jason,
Thank you for coming back to me, You can request a PAC code a few ways, please see below.
Text PAC followed by your date of birth in DD/MM/YYYY format to 65075 to receive a PAC Code from Virgin. By Phone: You can get a PAC Code by calling Virgin Mobile. To do this, call them on 789 using your Virgin handset. Alternatively, dial 0345 6000 789 from any other phone.
Kind regards
Paul.
