Anonymous VCP - what to list on pay.gov for plan sponsor, plan name and EIN

We are filing an anonymous VCP.  What should we use for plan sponsor, plan name, plan number and EIN on pay.gov?  We will redact the plan information in the attachments but what do we use for the online 8950 Form?

I know this is over 2 years later, but I happened to be looking at the 8950 instructions earlier today, and they have been updated to address these questions for current Anonymous VCP submissions.
