Show SKU numbers on product pages
Caution
Vintage themes aren't available in the Theme Store. Vintage themes don't have the features included in Shopify's Online Store 2.0 themes , and Shopify free vintage themes don't receive updates except security fixes.
Note
This customization is for vintage Shopify themes, and doesn't apply to Online Store 2.0 themes.
SKUs (stock keeping units) are numbers, typically alphanumeric, that are used to help identify products and track inventory. If a store uses SKUs, then a unique number is assigned to each individual product variant. You can show SKU numbers for variants on your product pages by editing your theme code:
Sectioned and non-sectioned themes
Note
The steps for this tutorial differ depending on whether you're using a sectioned or a non-sectioned theme. A sectioned theme lets you drag and drop to arrange the layout of your home page, and a non-sectioned theme doesn't.
To figure out whether your theme supports sections, go to the theme's Edit code page. If there are files in the Sections directory, then you're using a sectioned theme. Non-sectioned themes were released before October 2016, and don't have files in the Sections directory.
If you're using a sectioned theme, then click the Sectioned themes button and follow the instructions. If you're using an older, non-sectioned theme, then click the Non-sectioned themes button and follow the instructions.
Steps for Sectioned themes Show SKU numbers on product pages
From your Shopify admin, go to Online Store > Themes .
Find the theme you want to edit, click the … button to open the actions menu, and then click Edit code .

On a new line below the line of code that includes {{ product.title }}
, paste the following code:
{% assign current_variant = product . selected_or_first_available_variant %}
<span class="variant-sku">{{ current_variant . sku }} </span>

Steps for Non-sectioned themes Show SKU numbers on product pages
Note
This customization doesn't work for the non-sectioned Boundless theme. Non-sectioned themes were released before October 2016, and don't have files in the Sections directory.
Steps:
From your Shopify admin, go to Online Store > Themes .
Find the theme you want to edit, click the … button to open the actions menu, and then click Edit code .
In the Templates directory, click product.liquid
.
Find the following Liquid tag:
{{ product . title }}
This is the code that renders your product titles on the product page.
On a new line below the line of code that includes {{ product.title }}
, paste the following:
{% assign current_variant = product . selected_or_first_available_variant %}
<span class="variant-sku">{{ current_variant . sku }} </span>
Click Save .
If you're using a free Shopify theme that isn't Brooklyn or Venture, then find the following line of code:
var selectCallback = function ( variant , selector ) {
If you cannot find the above line of code in product.liquid
, then you will find it in theme.liquid
, in the Layout directory.
Brooklyn and Venture: If you are using Brooklyn or Venture, then you will need to find and edit a different line of code. In the Assets directory, click theme.js.liquid
, and find the following line of code:
theme . productVariantCallback = function ( variant , selector ) {
On a new line below, paste the following code:
if ( variant ) {
document . querySelector ( ' .variant-sku ' ). innerText = variant . sku ;
}
else {
document . querySelector ( ' .variant-sku ' ). innerText = '' ;
}
Your code should look something like this:
var selectCallback = function ( variant , selector ) {
if ( variant ) {
document . querySelector ( ' .variant-sku ' ). innerText = variant . sku ;
}
else {
document . querySelector ( ' .variant-sku ' ). innerText = '' ;
