I wouldn’t be able to confirm that. We gathered a php script for this job, we are more “designers” than “developers”, please see the script below (by the way, do you have a plugin that would do the job of this php script?):

add_filter('woocommerce_billing_fields' , 'display_billing_vat_fields');
function display_billing_vat_fields($billing_fields){
    $billing_fields['billing_vat'] = array(
        'type' => 'text',
        'label' =>  __('VAT number',  'woocommerce' ),
        'class' => array('form-row-wide'),
        'required' => false,
        'clear' => true,
        'priority' => 35, // To change the field location increase or decrease this value
    );

    return $billing_fields;
}

// Printing the Billing Address on My Account
add_filter( 'woocommerce_my_account_my_address_formatted_address', 'custom_my_account_my_address_formatted_address', 10, 3 );
function custom_my_account_my_address_formatted_address( $fields, $customer_id, $type ) {

    if ( $type == 'billing' ) {
        $fields['vat'] = get_user_meta( $customer_id, 'billing_vat', true );
    }

    return $fields;
}

// Checkout -- Order Received (printed after having completed checkout)
add_filter( 'woocommerce_order_formatted_billing_address', 'custom_add_vat_formatted_billing_address', 10, 2 );
function custom_add_vat_formatted_billing_address( $fields, $order ) {
    $fields['vat'] = $order->get_meta('billing_vat');

    return $fields;
}

    $replacements['{vat}'] = ! empty($args['vat']) ? $args['vat'] : '';
    $replacements['{vat_upper}'] = ! empty($args['vat']) ? strtoupper($args['vat']) : '';

    return $replacements;
}

    }
    return $formats;

function custom_customer_meta_fields( $fields ) {
    $fields['billing']['fields']['billing_vat'] = array(

    );

    return $fields;
}

add_filter( 'woocommerce_admin_billing_fields', 'custom_admin_billing_fields' );

    );
