When you initially enroll your Regions account with Zelle, you may receive a notification that your mobile number is registered with another financial institution. Only one account can be connected at any given time. View the Activity tab where a prompt allows you to "Transfer Phone" in your profile. This will connect the desired U.S. mobile number to your Regions account and you can start sending and receiving with Zelle through our Regions Online Banking site or Regions Mobile App. For assistance with this issue, contact us at 1-800-472-2265.
