By default, the billing passcode on a Verizon Wireless account is set to the last four digits of the account holder's Social Security number. Some users prefer to have a more secret or original passcode to help protect their accounts. Verizon Wireless allows users to change the passcode through "customer care."
Dial "*611" from your Verizon Wireless phone, or 1-800-837-4966 from another phone.
Select the option to speak with "customer care."
Tell the representative that you need to have your billing passcode reset.
