# Rename a country Add this code to your child theme’s `functions.php` file or via a plugin that allows custom functions to be added, such as the [Code Snippets](https://wordpress.org/plugins/code-snippets/) plugin. Avoid adding custom code directly to your parent theme’s functions.php file, as this will be wiped entirely when you update the theme. ```php if ( ! function_exists( 'YOUR_PREFIX_rename_country' ) ) { /** * Rename a country * * @param array $countries Existing country names * @return array $countries Updated country name(s) */ function YOUR_PREFIX_rename_country( $countries ) { $countries['IE'] = __( 'Ireland (Changed)', 'YOUR-TEXTDOMAIN' ); return $countries; } add_filter( 'woocommerce_countries', 'YOUR_PREFIX_rename_country' ); } ```
