If you still have something from Corus Bank, National Association
A lien that was never released
Corus Bank, National Association failed on Sep 11, 2009. For a failed bank placed in FDIC receivership, the FDIC may be able to issue the lien release, if the loan was paid off to the bank before it failed or to the FDIC afterward. The FDIC says that where a failed bank had an acquirer, its records in most cases went to that acquirer. Here the chain from the acquirer leads to Fifth Third Bank, National Association, which is worth asking too.
Requests go through the FDIC Information and Support Center with the recorded mortgage or title, and proof of payoff. The FDIC says to allow 30 business days once it has every document, and does not take requests by phone or email. Questions: FDIC Resolution Inquiries, 888-206-4662, 8am–4pm Central on weekdays.
An old account, passbook or CD
When a healthy bank assumes a failed bank's deposits, insured depositors become its customers right away (here, MB Financial Bank, National Association). Start with Fifth Third Bank, National Association, and ask them to search under the name Corus Bank, National Association.
For failures since mid-1993 the law sets a clock: insured deposits not claimed within 18 months of the FDIC starting to pay depositors are offered to the state of the depositor's last known address on the bank's records. If the state takes them, the owner has 10 years to claim there before the money returns to the FDIC. Check FDIC unclaimed funds search and that state's unclaimed-property program.
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. Today, ask Fifth Third Bank, National Association. 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.
One caution: banks also sell single branches. If the office you used was sold to a different bank along the way, the account went with the branch, not with this chain. The office list below shows which bank each office reports under now.
