A Google Business Help forum thread has a complaint from a local business owner that says Google has reverted the area code of his phone number on his Google+ Local listing.
Here is a picture of his listing:
The issue is that Google is replacing the area code by removing the 0 and adding a 1. He said:
(07) 3345 2097 will end up displaying as either 733452097 (minus the 0 at the start) or +1 733452097
Clearly this can be an issue for consumers looking to call the store from their phones.
Google is aware of the issue.

This is an issue that's affecting some international local-verified social local Google+ pages -- team's looking into it. Thanks for reporting!
