To find out if you have unclaimed retirement benefits, visit the website of the National Registry of Unclaimed Retirement Benefits, enter your Social Security number and perform a search. The registry matches former employees with the companies holding their unclaimed retirement funds and displays the results.
If you worked for a company that offered pension plans, contact the company to find if it has unclaimed benefits, suggests U.S. News and World Report. If you cannot find the company or it does not have a record of your benefits, contact the Pension Benefit Guaranty Corporation and provide your personal and work information. The corporation may help you find a lost pension or 401(k) plan.
