MissingMoney.com

MissingMoney.com is a web portal created by participating U.S. states to allow individuals to search for unclaimed funds. It was established in November 1999, as a joint effort between the National Association of Unclaimed Property Administrators (NAUPA) and financial services provider CheckFree. By December of that year, 10 states had joined.
, 39 states were participating in the program. In participating states, MissingMoney.com operates free of charge. In January 2017, the Minnesota Court of Appeals rejected a lawsuit against the state of Minnesota alleging that the state's use of MissingMoney.com as the sole means to distribute its unclaimed funds impeded citizens from receiving such funds. The website also provides information on the programs of states not participating in the national program.
The eleven states not using MissingMoney.com are Arkansas, California, Connecticut, Delaware, Georgia, Hawaii, Illinois, New York, Oregon, South Carolina and Wyoming.
