File Prefix / File Name
All file names submitted to RCB Bank should start with the assigned File Prefix, followed by the current date (MMDDYY) and a proper file extension. File extensions should reflect the kind of data in the file.

Prenote Transactions
A prenote transaction (transaction code 23, 28, 33, or 38) is a non-dollar entry sent through the ACH network. It conveys the same information (with the exception of the dollar amount and transaction code) that will be carried on subsequent entries. The prenotification process helps to ensure that subsequent entries are posted appropriately. This prenote transaction may be originated at any time, however, live dollar entries can not occur until 6 banking days after the effective entry date of the prenote. The prenote must carry an appropriate effective entry date to be processed through the system, it is not the date of the first live entry. EXAMPLE: A prenote transaction is created on June 5^th with the effective entry date of June 6^nd. A live transaction can begin no sooner than an Effective Entry Date of June 14^th. If any of the bank data (routing number or account number) should change, the new data must go through the prenotification process.
