Display SKU Next To Product Title in WooCommerce

While I don’t always necessarily understand the ‘why’ behind some of the WooCommerce requests I see in Facebook groups, I still take the opportunity to research a solution and learn something new. In this article, we will see how to append a product’s SKU (if it has one) to the Product title. This is how I imagined the best way to display the product SKU beside the Product title. However, I’m always open to suggestions…

I am modifying the Product title on both the Shop page and Single Product page in order to append the product SKU. I realize that the product SKU is generally already available on the Single Product page so this might not be a common requirement but more of an edge-case need.

Nevertheless, it is definitely a great learning opportunity.

Using the_title hook and the add_filter() function, we can create a callback function to return the modified Product title. I also want to plan for the event that a product may not have an SKU and append something more meaningful besides blank whitespace.

add_filter ( 'the_title', 'custom_woo_show_sku_with_title' , 9999, 4 );

function custom_woo_show_sku_with_title( $post_title, $post_id )
$product = wc_get_product( $post_id );

if ( ! is_admin() && 'product' === get_post_type( $post_id ) && $post_id === $product->get_id() )
$sku_display = empty( $product->get_sku() ) ? 'Not Available' : $product->get_sku();
$post_title = $post_title . ' (SKU: ' . $sku_display . ')';
return $post_title;

Visiting the code, here are some highlights:

  • The custom callback function, custom_woo_show_sku_with_title() accepts 2 arguments: the post title and the post id.
  • Use the wc_get_product() function and create a product object.
  • In the if() statement, there are 3 conditionals that must all evaluate to be true: 1) Not be on an administrative page. 2) Must be a product post type. 3) The product ID must be the same as the post ID.
  • Using the ternary operator, if a product doesn’t have an SKU, provide the message ‘Not Available’. Otherwise, use the product SKU.
  • Append the SKU (or message) to the product title and return it for output on the screen.

As shown in the following screenshots, all products on the Shop page and the Single Product page have an SKU or meaningful message appended to the Product title:
