WooCommerce: Show SKU @ Cart, Checkout, Order & Emails

When SKU matters to the end user, displaying it in the Cart page, Checkout page, Thank you page, My Account View Order page and Order Emails under the item name is a must.

Ideal for B2B businesses and international brands, this simple customization can help you learn how to add any sort of content under the Cart/Checkout/Order item names. Simply use the same hook and try “getting” something different than SKU with this guide. Enjoy!

With this handy snippet, echoing the SKU under each item in the Cart page is a breeze!

// First, let's write the function that returns a given product SKU
function bbloomer_return_sku( $product ) {
   $sku = $product->get_sku();
   if ( ! empty( $sku ) ) {
		return '<p>SKU: ' . $sku . '</p>';
	} else {
		return '';

// This adds the SKU under cart/checkout item name
add_filter( 'woocommerce_cart_item_name', 'bbloomer_sku_cart_checkout_pages', 9999, 3 );

function bbloomer_sku_cart_checkout_pages( $item_name, $cart_item, $cart_item_key  ) {
	$product = $cart_item['data'];
   $item_name .= bbloomer_return_sku( $product );
   return $item_name;

// This adds SKU under order item table name
add_action( 'woocommerce_order_item_meta_start', 'bbloomer_sku_thankyou_order_email_pages', 9999, 4 );

function bbloomer_sku_thankyou_order_email_pages( $item_id, $item, $order, $plain_text ) {
	$product = $item->get_product();
   echo bbloomer_return_sku( $product );

Where to add custom code?

You should place PHP snippets at the bottom of your child theme functions.php file and CSS at the bottom of its 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 guide "Should I Add Custom Code Via WP Editor, FTP or Code Snippets?" and my video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything went 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.

  1. Works perfectly for my site!

  2. Works like a charm! I’m using Riode Theme.

  3. Hi, Thank you for creating a very useful snippet to add SKU on cart, checkout, email and order detail pages. It is working correctly on Cart, checkout and order details page. However in an email, it is adding SKU value two times in this format.

    Product title (# SKU-value)
    SKU: SKU-value

    Any reason, why is it adding the value of SKU two times in an order confirmation email?

    1. Hi Manish, thanks for that! Do you use any email customizer plugin? If not, could you send me a screenshot?

        1. Thank you. Try adding this as well:

          add_filter( 'woocommerce_email_order_items_args', 'bbloomer_no_sku_admin_emails' );
          function bbloomer_no_sku_admin_emails( $args ) {
          	$args['show_sku'] = false;
          	return $args;
          1. I’ve got the same problem, but than on the Cart page. So the SKU is after the title and also in a new paragraph.

            1. Try with:

              function bbloomer_sku_cart_checkout_pages( $item_name, $cart_item, $cart_item_key  ) {
                 $product = $cart_item['data'];
                 $item_name .= is_cart() ? : bbloomer_return_sku( $product );
                 return $item_name;
              1. Hi there! I’ve got the same problem on the Cart page. The SKU is appearing in the title (inside the clickable link) and also in a new paragraph (without link).

                You can check this error here: https://prnt.sc/TOS03qs0sdyE

                I’ve tried to replace the “bbloomer_sku_cart_checkout_pages” function with the one you recommended above:

                function bbloomer_sku_cart_checkout_pages( $item_name, $cart_item, $cart_item_key  ) {
                   $product = $cart_item['data'];
                   $item_name .= is_cart() ? : bbloomer_return_sku( $product );
                   return $item_name;

                And after this, the SKU’s at the cart aren’t appearing anymore, and instead the products received an “1” entry inside the title, and an “1” outside the title.

                You can check this new error here: https://prnt.sc/6_MMIEJ36Hc5

                Can you help me?

                1. Try with:

                  $item_name .= is_cart() ? '' : bbloomer_return_sku( $product );
                  1. Hey!

                    I’ve tried with this new change, and the “11” glitch is gone, but the SKU isn’t appearing too.

                    Can you help me?

                    1. Not 100% sure, must be your theme?

  4. It’s adding empty   code after SKU code.

    1. Weird, screenshot please?

  5. Hi is there any way to add a SKU on a email quote.

    1. Hi Kyle, what do you mean by “email quote”?

  6. Not working for me 🙁 – using Avada theme…

    1. Not working anywhere? Avada may be customizing WooCommerce templates/function so it may need further customization

      1. Hello, has this issue been fixed for the Avada theme?

        1. Hi Drew, thanks so much for your comment! I’m afraid this is custom work. If you’d like to get a quote, feel free to contact me here. Thanks a lot for your understanding!

  7. It still works and it looks really nice. What about the checkout page (order summary)?

    1. Should work there too out of the box

  8. Yes it still works (2021). Works on the cart page/checkout but not on mini cart.

    1. Cool! The mini cart will require an additional piece of code
