My housemate moved this past Saturday and filed a "Family" change of address with USPS. He was getting mail for himself and his deceased mother, so he assumed that this would kill two birds with one stone and forward all mail with that last name instead of filing individual forwards for each of himself and his mother. Now, I am no longer getting my mail. I had two packages sent through USPS that were supposed to arrive on Wednesday. They never arrived and when I tracked them I see a final status of: Undeliverable as Addressed, November 10, 2010, 1:49 pm This is very strange since I have been ordering from Amazon at this address for well over a year and my address hasn't changed. Also it was two packages that were shipped from different facilities so it is highly unlikely that the addresses got obscured on both packages. I can only assume that somehow the "Family" change of address has indicated to USPS that everyone moved from this house not just those with his last name. Unfortunately today is veterans day so I can't get a hold of anyone at USPS. My question is: 1. What can I do about this? 2. What has happened to my packages? Are they being forwarded to his new address even though we have different last names and his CoA shouldn't have affected me? Is it being held at the Post Office distribution center because they somehow believe everyone from this house has moved but don't have a forwarding address on file for me? 3. What will happen to my packages? I just got some details from the PO and my mail carrier to clarify this situation. When my roommate filed the "Family" change of address, that basically says everyone in the household is moving. Since our last names aren't the same, he thought it would be okay. But what actually happens is that mail with his last name gets forwarded to his new address, while first class mail with my last name gets returned to sender. Due to the "Family" change of address he filed, the post office believes that every existing occupant moved out, and since they don't have a forwarding address on record for me, they begin returning my first class mail to sender as "undeliverable as addressed". He needs to go in and cancel the "Family" change of address, and then put in "Individual" change of addresses for himself and his deceased mother who's mail he had coming here. He thought it would be a shortcut to just "Family" COA with his last name to kill two birds with one stone, and in the end screwed my mail.
