WooCommerce: Add House Number Field @ Checkout

 A North European client told me they’re really strict about billing and shipping addresses over there. Couriers usually require a separate “House Number” in order to dispatch packages within those countries.

This must be therefore placed on the checkout, BESIDE the “Address_1” field and made required. Also, it’s a good idea to make this show in the Admin Order, thank you page and notification Emails.

Add House Number in the WooCommerce Checkout

Before coding…

If you don’t use the “Address_2” field you don’t need any customization! Just enable and make that field required via WordPress > Customize > WooCommerce > Checkout > Address 2 Field.

All you needed is now available to you. If you really require a little customization, that could be related to the “Address 1” and “Address 2” field placeholders. To edit and rename them use this snippet.

If, on the other end, you need a separate, new field (because you already use “Address 1” and “Address 2” and need a new “House Number” field), then you should look into this customization.
