Thank you for reaching out. Zillow For Sale By Owner listings coming over to Trulia is a new feature recently rolled out because of this we have confirmed there is a technical error regarding Zillow not sending us the Property Owner's phone number through the Buyer's Agent List located on the main photo of the property page that's why it is displayed in the contact info section. I apologize for the inconvenience it has caused you. I have manually updated your contact information from the listing page. Please allow 24 to 48 hours for the change to take effect on Trulia site.
Let me know if you have any question so I can assist you.
Thank you for using Trulia!
