Some financial institutions require dashes in their customers' account numbers.
Prior to these TPIS changes, account numbers with dashes could be entered by Claims staff only. System changes have been implemented to allow bank account numbers with dashes to process via tape, cartridge, or file transfer. In the past, the payee's account number would be changed even if the new routing number did not process. This caused payments to be deposited in the wrong financial institution. TPIS has been changed to prevent these erroneous direct deposit payments.
