The Verizon one time payment page can be used even if you aren't the account owner, or an account manager. You'll also get a balance due. You can just pay a portion of that.

This is a safer way to pay your bill instead of giving the money to the account owner.

All you need is your phone number and the account's billing zip code(usually the zip code of the account owner.)

For disconnected accounts you'll need your account number.

"Your Auto Pay discount has been suspended.
Hi Jared,
Due to a one-time credit card payment you will see a debit adjustment in the amount of your Auto Pay discount totaling $10.00 on your next bill.
The monthly Auto Pay discount you receive requires you to make payments with the bank account used to enroll in Auto Pay and be enrolled in paper-free billing. A one-time payment was processed on your account outside of these terms and has resulted in the loss of the discount for this billing cycle
If you have additional questions, please visit Auto Pay_FAQs"

So because I paid my bill early I am being punished? This is messed up. What does it matter what cars I us e to pay it?
