- Can't create a character on WoW Classic realm
- Error: You already have the maximum number of characters allowed on this account
- I deleted my Alliance characters to switch to Horde, but now I can't create a Horde character
Across all realms, you can have a maximum of 50 characters per World of Warcraft account and realm type: 50 in Modern WoW, 50 in WoW Classic Era, and 50 in Progression realms.
In addition, in WoW Classic Era realms only, you can have a maximum of 10 characters per realm and, on a PvP realm, you cannot create a character if you already have in it a character of the opposing faction.
Note: Some Wrath of the Lich King Classic realms are locked due to over-population. You cannot create your first character on a realm that is full. For an up-to-date list of locked realms, visit the Wrath of the Lich King Classic Discussion official forums.
