Sample NACHA File:
File Naming Convention - The batch file should be saved with a .nac file extension using the following naming convention.
| File Name | Description |
|---|---|
YYMMDDNN.NAC |
YY = Year, MM = Month, DD = Day & NN = Batch No Example: 04111401.nac Year=2004, Month=11, Day=14 & Batch Number=01 |
Note: The batch number is required. This is used to differentiate between batch files when a merchant sends more than one batch on the same day. If only one batch file is sent for a particular date, the batch number will always be entered as 01.
