Using Zelle with your Comun account is very easy, just follow these steps:
Download the Zelle app
Click "Get Started"
Enter your phone number
Write "Comun" and click on "Don't see your bank"
Enter your email and verify the code that Zelle sent you
Write the card information of your Common account
Please keep in mind that the email associated with your Zelle account does not necessarily need to match the one linked to your Comun account. However, the card details do have to be the same!
