As per What are Salesforce ID's composed of?, the 4th and 5th character of a Salesforce ID can be used to identify which pod/server the record was created on. Note that due to events like pod migrations the pod identifier may no longer match the actual pod the record is hosted on.

What are the current mappings?

  • @ca_peterson It will always be a work in progress and still has some gaps to fill. But sure, why not. Commented Jul 18, 2017 at 8:46

As per Converting the Salesforce Pod Id to ServerUrl/Name, I started the mapping process from the source code of Workbench.

That list however is largely out of date. As a community resource I've compiled the list from orgs I have access to. Please feel free to fill in gaps as you can.

B0 Pre-Release: GS0


xx Not affiliated with a Pod 

Source on xx

  • "Pre-Release NA1"? I've never heard of such a pod. Outside of GS0 prerelease is on sandboxes. ... what is it? Commented Jul 18, 2017 at 4:10
  • @ca_peterson It came from the Workbench source code - line 272. I think I'll remove it as it is conflicting with NA21. Commented Jul 18, 2017 at 8:44
