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.

Just got off the phone with my Yahoo Local sales rep. I've been trying to work out a bulk upload deal of their enhanced listings the past couple of weeks and it's been slooow to say the least.
I just heard from him that they no longer support bulk listings and the only way I could work with Yahoo would be by using LocalWorks (which is Yext).
