Using Paypal , after placing an order customer is directed to paypal , inputs the email CC information and etc and is directed back to magento where they choose shipping and then click on place order.

I am getting this error:

Failed address validation %1

In the system log : Failed address validation, Email has a wrong format However Email is valid with Paypal email address.

Any help would be appreciated.

The full error is:

  • Looks like Customers -> Enable Auto Group Assignment set to "No" fixed the issue. I'm still testing to confirm this. Mar 8, 2021 at 7:29

1 Answer 1


According to the bug reports on get such as /issues/29473 and issues/25399.

Both suggest that the option

Enable Automatic Assignment to Customer Group

is causing the issue when set to "Yes" in the

Customers > Customer configuration settings section.

Thus, setting this option to No will provide a workaround the checkout issue.

Setting "Store > Configuration > Customers > Customer Configuration > Enable Automatic Assignment to Customer Group" to "No"


PayPal Express Checkout configured with option "Skip Order Review Step" to "No"

Paypal setting may contribute to the issue, it did not in my case as I once changed the customer auto assignment to No the issue was fixed.
