WooCommerce: Add a New Country For Billing/Shipping

There are times when the WooCommerce countries database is simply not enough. While the WooCommerce team is usually very fast at updating its code (though, the newest country is apparently South Sudan, which became independent in 2011, the year WooCommerce launched!), you may need to DIY in certain cases.

Think of Northern Ireland for example. It’s not a “country”, however most Irish businesses would ship to Northern Ireland and not to “UK”, so having “Northern Ireland” in the Checkout page country dropdowns may help.

In this edge case study, we’ll basically take a look at how to add a custom country, how to make sure this custom country shows at checkout as a possible option (and in the shipping zones admin section), and also how to assign to it a custom list of states. You never know!

Northern Ireland is now in the list of WooCommerce Billing & Shipping countries, thanks to the snippet below!

add_filter( 'woocommerce_countries', 'bbloomer_add_country' );

function bbloomer_add_country( $countries ) {
	$new_country = array(
		'XI' => 'Northern Ireland',
	);
	return array_merge( $countries, $new_country );
}

add_filter( 'woocommerce_continents', 'bbloomer_add_country_to_continent' );

function bbloomer_add_country_to_continent( $continents ) {
	$continents['EU']['countries'][] = 'XI';
	return $continents;
}

add_filter( 'woocommerce_states', 'bbloomer_add_country_states' );

function bbloomer_add_country_states( $states ) {
	$states['XI'] = array(
		'AN' => 'Antrim',
		'AR' => 'Armagh',
		'DY' => 'Derry',
		'DO' => 'Down',
		'FM' => 'Fermanagh',
		'TR' => 'Tyrone',
	);
	return $states;
}

Where to add this snippet?

You can place PHP snippets at the bottom of your child theme functions.php file (delete "?>" if you have it there). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7.3.
