Direct Debit File Formats

For direct debit transmission files, sections of the transmission file contain a specific amount of numbers or letters. These characters represent a text string. A text string contains sections that are explained in the following file format tables. For direct debit transmission files, the text string is referred to as a fixed length file. Every section in a fixed length file has a limit. For example, in a fixed length transmission file that has 40 characters, characters 1-8 have a designated meaning, and characters 9-22 have another meaning.

These tables explain the information that appears in a transmission file.
