Who Needs Your New Address?

Changing your address takes time, but it’s much easier to deal with it before any problems arise from missing mail. We know it’s difficult to keep track of all the places you need to update your address amid the chaos of moving into a new home, so here’s a checklist to make it a little easier.

Not all the organizations and agencies on this list will apply to you. Some of the urls are relevant regardless of where you move to/from, some only concern Washington State, and others only concern King County. For the purpose of this checklist, we’re assuming you live in the city of Seattle.



Post Office

Notifying the post office online will forward any mail sent to your old place to your new one for 12 months. You can set it for a specific start date, so you should do this at least a week before moving day—any later and there may be a gap between when you move and when your mail forwarding can begin.
