Question

In magento 2 what is "form_code" for customer address attribute to show on checkout step?

I know in magento 2 form_codes are used to show customer address attributes on the customer registration, address book, manage customer address from admin and checkout step.

For customer registration we use form_code "customer_register_address", for address book we use form_code "customer_address_edit", for manage customer address from admin we use form_code "adminhtml_customer_address".

But I did not found any form_code code used to show customer address attribute on checkout step. What is "form_code" for customer address attribute to show on checkout step?

Answer 1

There is only above mentioned three form_code we have to play with customer's addresses. Can you check once customer_address?. I think it can be a form_code work for you. Not Sure!

Answer 2

customer_register_address is form_code for customer address attribute to show on checkout step. You can find in Magento\Checkout\Block\Checkout\LayoutProcessor function getAddressAttributes()
