If you still have something from First Security Bank of Wyoming
A lien that was never released
The FDIC record shows no successor bank for First Security Bank of Wyoming. The FDIC says it may be able to help only where the lender was a failed bank placed in FDIC receivership.
Our suggestion, not the FDIC's: a title company or real-estate attorney in the county where the lien is recorded will know how that state clears a lien from a lender that no longer exists.
An old account, passbook or CD
With no successor bank to ask, go to the unclaimed-property program of the state of the owner's last known address on the bank's records. The OCC gives the same advice for old records from a bank that no longer exists.
Accounts nobody touches are eventually turned over to a state. The OCC puts the usual wait at three to five years with no activity, set by each state's law. Search the unclaimed-property program of the state of the owner's last known address on the bank's records, and any other state they lived in. It is free to search and to claim through a state's own site, and MissingMoney.com, an official site of the state administrators' association, searches most states at once.
A safe deposit box
Contents of boxes left behind are handled under state unclaimed-property law. Start with the unclaimed-property program of Wyoming, where the box was.
Box contents are not covered by FDIC insurance.
Not sure this is your bank?
Many banks shared a name. Match the city and the years above against your paperwork, or search again with the town.
Credit unions were never FDIC-insured and are not in this record; the NCUA credit union lookup covers those. Banks that closed before about 1970 are not in the FDIC's list either.
