Overriding class-wc-countries.php

Class methods cannot be overridden via a theme.

What are you attempting?

Well, I want to display the street as billing_address_1 and the number as billing_address_2, and that is also programmed well in our website.

But on the invoice and in the emails, the number is displayed under the street, but it needs to be displayed next to the street.

So I changed class-wc-countries.php, but then I need to change it every time I update WooCommerce…

The address formats in the countries class are filterable – no need to edit the file directly.

O, I didn’t know that.
How do you do that then?
