What do these specific Shopify Source Name codes mean?

[murray4]

Can someone please tell me which specific Shopify Source Names the following codes relate to?
580111
3890849
1830279

I'm segmenting customers by channel in Klaviyo and they appear as 'Source Names', along with 'web' and 'shopify_draft_order'.

But these numbers are useless, unless we can identify what they actually mean.

3890849 - I've seen it in orders created by Shopify's "Shop" App.

Edit: I found this also,  please have a look - https://learn.fueled.io/apps/shopify/google-analytics-4-connector/configuring-fueleds-shopify-app/sh...
