How to enroll in Zelle

There are many banks and credit unions in the U.S. that offer Zelle, including Bank of America, TD Bank and Capital One. If yours is one of the participating banks, it may allow you to enroll via the mobile banking app or online banking site.

Some banks allow you to sign up using your existing banking username and password, according to Zelle.

Download the Zelle app and you'll be prompted to add your banking username and password. This will direct you to your bank's secure site. Once you've added your banking information, you'll be redirected back to the Zelle app.

You will then have to set up another password for your Zelle. The different password is an "additional security feature," Zelle reports. If your mobile device has the Touch ID or fingerprint features, you may also use that to log into Zelle.

Zelle does not accept credit cards, international debit cards or international deposit accounts for use when making an account. Additionally, checking accounts used for Zelle must be based in the U.S.
