The FDIC has its own procedures for handling all deposit accounts of an institution after the initiation of the payment of insured deposits. 12 USC 1822(e). The statutory text describes the FDIC’s procedures:

 1822(e) Disposition of unclaimed deposits 

1822(e)(1) Notices.— 

1822(e)(1)(A) First notice.—Within 30 days after the initiation of the payment of insured deposits under section 1821(f) of this title [12], the Corporation shall provide written notice to all insured depositors that they must claim their deposit from the Corporation, or if the deposit has been transferred to another institution, from the transferee institution. 

1822(e)(1)(B) Second notice.—A second notice containing this information shall be mailed by the Corporation to all insured depositors who have not responded to the first notice, 15 months after the Corporation initiates such payment of insured depositors. 

1822(e)(1)(C) Address.—The notices shall be mailed to the last known address of the depositor appearing on the records of the insured depository institution in default. 

1822(e)(2) Transfer to appropriate state.—If an insured depositor fails to make a claim for his, her, or its insured or transferred deposit within 18 months after the Corporation initiates the payment of insured deposits under section 1821(f) of this title [12]— 

1822(e)(2)(A) any transferee institution shall refund the deposit to the Corporation, and all rights of the depositor against the transferee institution shall be barred; and 

1822(e)(2)(B) with the exception of United States deposits, the Corporation shall deliver the deposit to the custody of the appropriate State as unclaimed property, unless the appropriate State declines to accept custody. Upon delivery to the appropriate State, all rights of the depositor against the Corporation with respect to the deposit shall be barred and the Corporation shall be deemed to have made payment to the depositor for purposes of section 1821(g)(1) of this title [12].
