DCEASED Universe Number

Does anyone know what U- Number the DCEASED Universe falls in at?

All the Elseworlds Universes were actual ‘Alt-Universes’ within continuity, but I can’t find it anywhere…

It doesn’t look like it’s been given an official designation just yet. At this point, it might be up to Tom Taylor if he wants to reveal one in Unkillables or a possible future sequel. And welcome to the community!
