Hey Brian
Thanks for reaching out. To provide more clarity. Facebook and Google URLs cannot be submitted to Moz Local to verify against. Our verification is a query of the business name and zip code directly to those services and they decide which ones to return as the closest match. If you have duplicate Google and Facebook pages, it is best to make sure those are removed prior to publishing a listing through Moz to avoid being validating against the wrong page. It's much easier when there is only one of each available for Google or Facebook to return. Then you only need to update these pages for any changes or updates to the NAP.
If you can send us details of the listing you are referring to, we can take a look at help@moz.com
If you need the listing to verify against a different Facebook or Google URL, please also include those links in the message as well.
Hope this helps!
