ACH trace number: finding a missing payment

Short answer

An ACH trace number is a 15-digit identifier assigned to an ACH entry by the originating bank. It helps identify a particular payment. If a direct deposit is missing, start with the organization that sent it and your bank or credit union. Ask for the trace number and the payment’s date and amount so the investigation follows the correct entry.

Identify the payment before asking for a trace

Write down who sent the money, its amount and the expected deposit date. Keep the sender’s confirmation alongside your bank record. If several similar payments are involved, describe which one is missing.

Nacha’s consumer guidance directs people with ACH payment questions to their bank, credit union or the organization initiating the payment. For a direct deposit sent to another bank or the wrong account, it specifically points to the sending company or government agency. Nacha itself does not process individual payments or have access to their records.

Ask for the ACH entry’s identifier

Nacha’s file specification defines a 15-digit trace-number field assigned by the originating depository financial institution, usually shortened to ODFI. The field identifies an entry within its batch and file. The specification has separate fields for the recipient account, amount and an optional identification number.

Ask the sender to confirm that the reference supplied is the ACH trace number for the payment you are discussing. Preserve the complete value when giving it to the bank through a secure channel.

What the banks can investigate

The Federal Reserve’s Payment Trace Request procedure lets an originating bank ask the receiving bank about a payment’s status, including whether it was received, returned or posted. Its required information includes the trace number, amount, settlement and effective-entry dates, and bank and account details.

That is a bank investigation process. It does not establish a public tracking website where a consumer can enter a number and see a live location. Ask your own bank what it can confirm and whether it needs the sender or originating bank to take the next step.

For example, if payroll says a deposit was sent but the bank cannot match it, ask payroll for the trace number for that exact payday. Give the bank the number with the amount and date, then keep its case reference. This is a suggested way to organize the conversation; it does not promise a resolution time.

For the timing question, use ACH transfer pending. If the bank reports that an entry was returned, our ACH return codes guide explains the return reason separately.
