    • A voided check must have the name and address printed on it (no counter checks).
    • A bank letter with bank signature (must be on bank letterhead, and include the vendor’s information and account/routing number).
    • A 1199A, or a preprinted direct deposit form generated from the vendor’s bank.
    • The preprinted direct deposit form must be generated by the vendor’s bank and have the routing and account number
      TYPED on the form and must be signed and dated by the vendor’s representative. All
      banking must indicate the type of account (checking/savings).
