Hi,
yes you can use the hook woocommerce_order_item_meta_end

add_action('woocommerce_order_item_meta_end', 'ts_order_item_meta_end', 10, 4);
function ts_order_item_meta_end($item_id, $item, $order, $plain_text)
{
	$product = $item->get_product();

	$code = $product->get_meta('_wpm_gtin_code');
	
	echo ' - ' .$code;
}

Im sorry there’s only the possibility to add one code.

Hello,
please don’t stalk me, only this thread is enough.

These are hooks:

$action   = apply_filters( 'wpm_pgw_show_single_product_message_position_action', $action, $position, $priority );
		$priority = apply_filters( 'wpm_pgw_show_single_product_message_position_priority', $priority, $position, $action );

you can filter the action and also the priority.

Hello,
@du2llla the single page of the product is made with Elementor so the hooks of WooCommerce aren’t present inside the page, for this reason, you don’t see the GTIN code.
Also, you are using an SEO plugin that overrides WooCommerce Product Structured data, so the GTIN con is not found by Google Console.

Sometimes is not good to use plugins that remove the original hooks and feature of others. On the other and there are a lot of these plugins and to do the integration with all is quite impossible.

Hello,
in a standard theme like twenty twenty, storefront .. it works fine.
See the screenshot:

It is possible the your theme changed the position of the element inside the single product page.
