How many digits are in a Trace Number?

The correct answer is: 15

The Trace Number in an ACH transaction is composed of 15 digits. This number serves a crucial purpose in tracking and identifying each transaction within the ACH network. The format of the Trace Number comprises a combination of the Routing Transit Number (RTN) of the receiving financial institution followed by a unique sequence number that distinguishes this specific transaction. Having a 15-digit Trace Number allows for a sufficient range of unique identifiers, which is essential for the efficient processing and reconciliation of transactions within the ACH system. The structure of the Trace Number is specifically designed to provide clear identification without leading to confusion or overlap, which ensures accuracy in both record-keeping and dispute resolution processes. The other options are not correct because they do not reflect the established industry standard for the length of the Trace Number. For example, a 10-digit number would not provide enough uniqueness, while 12-digit or 20-digit configurations are not utilized within the ACH framework.
