A Local Search Forum thread has local SEOs claiming that Yahoo is no longer accepting or offering the local bulk listings services. Instead, these local SEOs are being told to contact LocalWorks, which is powered by Yext.

Yahoo recently announced they are discontinuing their maps service, so I guess this makes sense. It does seem like Yext is taking up more of the local listing share, outside of Google.
