You will receive a confirmation number via email if you have recently created a My Trulia account. This code is used to ensure that you supplied us with a valid email address when you confirm your account but it is not necessary to mange listing information.
If you have submitted listing information to us via Trulia's Single Listing Submit you can manage that information in the My Listings section of your My Trulia account. For more information please access the link below.
