If you had money in one of these plans

  1. Call Fidelity (fidelity.com), which runs the Agere Systems Pension Plan. With your Social Security number and the plan name, it can tell you whether you still have a balance and, if not, where it went.
  2. Or call the plan administrator listed on the plan below ((408) 433-8000). That number was filed for 2024; ask for the benefits or retirement plan office.
  3. If your plan closed, unclaimed balances usually went to an IRA in your name, to the PBGC's missing participants program, or to state unclaimed property. Here is how to check each one.
  4. Still stuck? The Department of Labor's benefits advisers help for free: askebsa.dol.gov or 1-866-444-3272. Never pay anyone to find your own money.
