If you are the account owner, log into your MyVerizon account.
Under the column, PROFILE is a button for Change Mobile Number
That is where you can choose a new number, even in another state.
Keep in mind there will also be an option on WHEN to change the number. Today or the beginning of the new billing cycle.
If you change it today, you may end up with overage charges and your plan will be prorated for each number for this month.
