Welcome to Trulia and thank you for your question. Photos and open house information are editable for all listings at this time, however other listing information can only be edited for those listings that have been submitted to Trulia manually.
We receive your listing information from Century 21 and they don't provide us with the complete address information for all of your listings. In order to ensure that this information shows up on our site, please contact Century 21 to request that they add the missing address information to their site and to the data feed they send to us. Once they update their data feed, our display will update automatically to show the address information thereafter.
Please let us know if you have any additional questions or feedback for us.
