In an ACH batch, entries are organized by entry hash. The entry hash is a numeric representation that is derived from the routing number and the account number associated with the transaction. It serves as a unique identifier for all of the entries within an ACH batch, ensuring that the transactions can be accurately processed.

Organizing entries by entry hash helps streamline the processing of ACH transactions by allowing for efficient identification and verification. It allows the processing system to group transactions that are destined for the same financial institution and aids in error detection.

While transactions can be analyzed or reported based on transaction type, dollar amount, or routing number for various purposes, those factors do not dictate the organizational structure of an ACH batch itself. Instead, the entry hash is the key element that actually organizes and facilitates the processing of entries within that batch.
