Shopify Theme Store ID 911 is Spark

Every Shopify storefront stamps the ID of the theme it installed into its own page source, and that number survives being renamed, customized, or delisted. Paste it here and we will tell you which theme it is, from the stores actually running it.

Quick answer

Shopify theme store ID 911 is the theme Spark, and the newest version we detect running under it is 4.0.4. That answer is the majority reading across the live storefronts we scan that report this ID, so one renamed theme cannot skew it.

Latest version detected in the wild: 4.0.4

A store running an older version than this is behind on theme updates, which is worth checking before you blame the theme for a bug.

Frequently asked questions

What theme is Shopify theme store ID 911?
Theme store ID 911 is Spark. That is the theme Shopify listed under this ID, and it stays true for any store carrying the number, whatever the theme has been renamed to since. We read it from live storefronts running the ID rather than from a published list, because Shopify does not publish one.
What is the latest version of Spark?
The newest version of Spark we detect on a live store is 4.0.4. If a store on ID 911 reports an older number than that, it has not taken the theme's updates, which is worth ruling out before blaming the theme for a bug.
My store's code shows ID 911 but a different theme name. Which one is right?
The ID. The name in Shopify.theme is whatever the store owner or their agency typed, and renaming a client theme is routine, so a store on ID 911 can call it anything at all. The number was set by Shopify at install and cannot be edited, so a store reporting 911 is running Spark regardless of the label next to it.
How do you know ID 911 is Spark?
By agreement across the storefronts running it, not by one store's word. We group every scan that reports ID 911 and take the name most of them give, and the ID is only published here once enough separate stores agree. A few renamed copies get outvoted instead of counted, and readings where our detector could not name the theme are dropped before the vote rather than treated as a name.
Does theme store ID 911 change if I customize or rename Spark?
No. Editing the Liquid, restyling it beyond recognition, or renaming it in your admin leaves ID 911 exactly where it was. Shopify stamps the ID in when the theme is installed and never rewrites it, which is why it still identifies Spark years later, and why it keeps working after Shopify retires a theme from the Theme Store.
How do I check whether a store is running Spark?
Open the storefront's page source and search for Shopify.theme. If the theme_store_id field there reads 911, the store is on Spark, whatever the name beside it says. Our scanner reads the same field, along with the theme version and the apps the store runs, if you would rather not read the source yourself.

How this data works

Theme store IDs, theme names and versions are read from the storefront itself on every scan our detector runs, so the mapping is evidence from live stores rather than a curated list. Each ID is named by majority agreement across the stores reporting it, and an ID with too little agreement behind it is left unpublished instead of guessed at.

Independent by design: rankings are determined solely by live detection data. Affiliate relationships never affect what ranks or how stores are counted. Read the full methodology →
