Remove the Additional Information and Order Notes fields in WooCommerce

You can remove the Additional Information and Order Notes fields in WooCommerce checkout page with 2 filters that you add to your themes functions.php file

woocommerce-additional-order-notes

The first filter woocommerce_enable_order_notes_field is returning false and will not display the ‘Additional Information’ heading and also the order notes field, I have found it needs to be run with a high priority sometimes, that’s why I have added in the ‘9999’.

 

The second filter woocommerce_checkout_fields is removing the order notes field.
