What term is used to describe the summation of routing numbers contained in a batch?

Entry Count
Batch Total
Entry Hash
Routing Summary

The correct answer is: Entry Hash

The term that accurately describes the summation of routing numbers contained in a batch is known as the Entry Hash. This is a crucial component of the Automated Clearing House (ACH) processing system. The Entry Hash serves as a method of verifying the integrity of the batch of ACH entries by summarizing the routing numbers into a single value. When the ACH file is processed, the Entry Hash is calculated by taking the first eight digits of each routing number in the batch, summing them up, and representing that sum as a single number. This helps in ensuring that the batch has not been altered and that all entries are accounted for, facilitating efficient and error-free processing of the transactions. In contrast, the other terms relate to different aspects of the ACH process. The Entry Count indicates the total number of entries included in the batch, while the Batch Total refers to the total dollar amount of all the entries in the batch. Routing Summary is not a standard term used within the ACH framework. Understanding these distinctions is key to grasping the operational functions within an ACH environment.
