R63 ACH Return Code: Incorrect Dollar Amount

What Causes ACH Return Code R63?

The R63 ACH return code means "Incorrect Dollar Amount" and indicates that the dollar amount specified in a return entry doesn't match the dollar amount of the original transaction being returned. This return ensures precision in the ACH network by catching discrepancies when returns are processed with incorrect amounts.

R63 returns typically occur during the return process itself rather than the original transaction. When a bank needs to return a transaction and creates a return entry, the dollar amount in that return entry must exactly match the original transaction amount. If there's a mismatch—whether due to data entry errors, system glitches, or processing mistakes—the return will be flagged with R63 to maintain transaction accuracy.

Can You Retry R63 Payments?

You can address R63 returns by working with the receiving bank to correct the dollar amount discrepancy. Since this is an error in the return process rather than the original transaction, resolution involves ensuring the return entry uses the correct dollar amount that matches the original transaction. Once the amount is corrected, the return can be reprocessed properly.

How to respond

An R63 return requires immediate verification of transaction amounts and coordination with the receiving bank to correct the dollar amount discrepancy in the return entry.
