If you had money in one of these plans

  1. Call T. Rowe Price (troweprice.com), which runs the Sanofi U.S. Group Savings 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 ((908) 981-6000). That number was filed for 2024; ask for the benefits or retirement plan office.
  3. 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.
