R64

Incorrect Individual Identification

Individual identification numbers don't match between original and return entries.

What Causes ACH Return Code R64?

The R64 ACH return code means "Incorrect Individual Identification" and indicates that the individual identification number in a return entry doesn't match the identification number used in the original transaction. This return ensures accuracy in the ACH network by catching discrepancies in personal identification information during the return process.

Individual identification numbers can include Social Security Numbers, employee ID numbers, customer reference numbers, or other unique identifiers used to link transactions to specific individuals. R64 returns typically occur when banks process return entries and the identification information doesn't match what was used in the original transaction, creating a data integrity issue that must be resolved.

Can You Retry R64 Payments?

You can address R64 returns by working with the receiving bank to correct the individual identification number discrepancy. Since this is an error in the return process where ID numbers don't match, resolution involves ensuring the return entry uses the correct individual identification number that matches the original transaction. Once the identification information is corrected, the return can be reprocessed properly.

How to respond

An R64 return requires immediate verification of individual identification numbers and coordination with the receiving bank to correct the ID discrepancy in the return entry.

When receiving payments

  • Contact RDFI's ACH Operations
    Reach out to the receiving bank's ACH operations team to report the individual identification number discrepancy between the return and original transaction.
  • Provide Both ID Numbers
    Give the bank the individual identification numbers from both the original entry and the return entry to help them identify the mismatch.
  • Request Return Reversal
    Ask if the bank can reverse the incorrect return so that a new return with the correct individual identification number can be initiated.
  • Verify ID Information
    Double-check that all individual identification numbers match your records and customer information before reprocessing.

When sending payments

An R64 return on vendor payments indicates that a return entry was processed with individual identification information that doesn't match the original transaction. This requires working with banks to correct the ID discrepancy.

  1. Contact the receiving bank's ACH operations team to report the individual identification number discrepancy
  2. Provide both the original transaction ID number and the incorrect return entry ID number
  3. Request that the incorrect return be reversed so a corrected return can be processed
  4. Verify all individual identification information is accurate before reprocessing to prevent future R64 returns
