I am trying to locate my old 401k from a company I left 7 years ago. I know they changed plan administrators, but the current administrator has no record of it. The company is not returning my calls. I have searched the PBGC unclaimed pensions as well as our state unclaimed property list. Any ideas?
Depending on how the change in plan administrators occurred and what happened to your particular account based on that transfer, the previous administrator might've tried to reach you at a place you could no longer be reached. In that case, in order for the prior plan administrator to free themselves of the responsibility of looking for you forever, they would've escheated the money to the state. There are services which will help you find any money in your name such as http://missingmoney.com/ and http://unclaimed.org/, but I have no personal experience with these sites. Each state should also have this information available, or available on reques. If the state has money in your name, it should be straightforward getting it back into your hands.
