Earlier this year, we reported that Google was working on a way for Google Apps accounts to verify Google+ pages.
A few months later, Google says Google Apps users can now verify their Google+ Local Pages.
Jade from Google's support team said in the ongoing thread at Google Business Help:
Unpinning because I believe this issue has been resolved. If you see this issue, please make a new thread.
She was then asked to clarify, where she said:
Yes, I believe Google Apps accounts may now verify the social local G+ pages.
I have not personally tested this but Google says it works.
