If you still have something from Sweetwater Federal Savings and Loan Association
A lien that was never released
Sweetwater Federal Savings and Loan Association failed on Aug 22, 1990, handled by the Resolution Trust Corporation, the agency that closed failed savings institutions from 1989 to 1995. The FDIC's lien-release page covers failed banks and savings and loans placed in FDIC receivership; it does not say how releases work for resolutions this old.
Call FDIC Resolution Inquiries at 888-206-4662 (8am–4pm Central, weekdays) and ask whether the FDIC holds this institution's receivership. The FDIC's own instructions are at FDIC, Obtaining a Lien Release.
An old account, passbook or CD
When a healthy bank assumes a failed bank's deposits, insured depositors become its customers right away (here, First Security Bank of Rock Springs).
This failure is older than the current federal rule on unclaimed deposits (mid-1993), so different rules apply. Search FDIC unclaimed funds search, search the unclaimed-property program of the state of the owner's last known address on the bank's records, and ask FDIC Resolution Inquiries at 888-206-4662 what applies to this institution.
A safe deposit box
The FDIC says that when a healthy bank assumes a failed bank's deposits, the branches usually reopen the next business day with box access. A box abandoned for years may have been turned over to the state's unclaimed-property program.
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.
