What must Third-Party Senders provide upon the ODFI's request?

The correct answer is that Third-Party Senders must provide information related to each Originator upon the ODFI's request. This requirement is rooted in the necessity for the Originating Depository Financial Institution (ODFI) to conduct proper due diligence on the entities it does business with, ensuring compliance with regulations and risk management practices.

Third-Party Senders act as intermediaries that facilitate the transmission of ACH Entries from various Originators to Receivers. Therefore, it is crucial that ODFIs have access to detailed information about each Originator, which may include their operational practices, financial soundness, and compliance with applicable laws. This information helps the ODFI assess the risk associated with processing entries from the Third-Party Sender and ensures that the transactions are legitimate and authorized.

Understanding this requirement is essential for maintaining a robust ACH network, as it promotes transparency and accountability among the parties involved in the electronic funds transfer process.
