Zelle is an online service to transfer funds that aim to replace the traditional methods of cash or cheque. It is completely reliable as all transactions occur to and from bank accounts only. It has a very large network across many banks of the United States and hence it is not a rare sight to experience unfavorable situations where you may encounter an error while accessing your account or making transactions.
This type of error is prompted when you are unable to enroll with Zelle with your phone number or email address.

If you have changed your financial institution and are trying to enroll again with the same phone number you first need to remove your phone number or email address from the account using which you previously enrolled
