All persons so notified shall forthwith after receipt of the notice advise the board of all such credits, other personal property, or debts in their possession, under their control, or owing by them. If such notice seeks to prevent the transfer or other disposition of the deposit in a bank or other credits or personal property in the possession or under the control of a bank, the notice to be effective shall state the amount, interest and penalty due from the person and shall be delivered or mailed to the branch or office of such bank at which such deposit is carried or at which such credits or personal property is held. Notwithstanding any other provision, with respect to a deposit in a bank or other credits or personal property in the possession or under the control of a bank, the notice shall only be effective with respect to an amount not in excess of two times the amount, interest and penalty due from the person.
