So, whilst doing some work with IBM Cloud, I needed to locate the GUID for my IBM Cloud Object Storage (COS) instance.

If I then click on either the Group ( Default ) or the Location ( Global ) or
the Product ( Cloud Object Storage ), a slide-in appears on the right-hand side of the page, with details of the instance including the GUID: -
As an alternative, and perhaps better for scripting and automation, the GUID is available "programmatically" : -
ic resource service-instance "Cloud Object Storage-dp" --output JSON | jq -r ..guid
