``` * I find out that get_order_country() does not exist, only get_shipping_country() and get_billing_country(). Somehow it uses ‘order’ as $fieldset_key.

Please create a country field in the Additional Fields sections by giving the section name along with the field name(for eg: **_order\_country_** for Additional Fields section) and verify it from your side. * Thank you! * Thread Starter [vartas](https://wordpress.org/support/users/vartas/) * (@vartas) * [3 years, 5 months ago](https://wordpress.org/support/topic/additional-field-postcode-validation-error/#post-16337163) * Thank you for your response. I wanted to try that, but I am using free version and I do not see Country type option when adding new field. Is it because free version? * Plugin Author [ThemeHigh](https://wordpress.org/support/users/themehigh/) * (@themehigh) * [3 years, 5 months ago](https://wordpress.org/support/topic/additional-field-postcode-validation-error/#post-16340330) * Please create a hidden field with the name **_order\_country_** for Additional Fields section and provide the country code in the default value field. Thank you! * Thread Starter [vartas](https://wordpress.org/support/users/vartas/) * (@vartas) * [3 years, 5 months ago](https://wordpress.org/support/topic/additional-field-postcode-validation-error/#post-16341723) * Added and working. But what if we ship to more than one country? * Plugin Author [ThemeHigh](https://wordpress.org/support/users/themehigh/) * (@themehigh) * [3 years, 5 months ago](https://wordpress.org/support/topic/additional-field-postcode-validation-error/#post-16345180) * Please try adding the below code in your active theme’s functions.php file, so that the shipping country value will be directed to the order country field. * ```wp-block-code add_action('wp_footer','wcfe_set_country_code'); function wcfe_set_country_code(){ ?>
