Many users can keep their existing phone numbers when switching to Verizon, though the company states that a variety of factors can prevent a number from being ported. The Verizon website allows a user to see if her phone number is eligible for transfer.
A user can check her transfer eligibility by entering her current phone number on the Verizon website. The online interface can then determine if the number is available to be switched over to Verizon service. Users can also check the status of a current number transfer on the website. When buying a phone online, a user can enter her current phone number to switch it over. Sales associates at Verizon retail locations can also help port over numbers.
