What R03 means
The routing number reached the right bank, but the account number does not correspond to anything there — or the name and account number do not match well enough for the bank to locate it. Usually a typo, a transposed digit, or a leading zero that a spreadsheet stripped.
What to do next
Check the account number against what the recipient gave you, paying attention to leading zeros. Keep bank fields formatted as text in your spreadsheet so they are not silently truncated, and send a prenote to verify before the next live run.
Can this happen on a file from this generator?
Yes. R03 can come back on a credit file, so it is worth guarding against. Verify account details with a zero-dollar prenote before the first live payment, and check the file's structure with the ACH file validator before you upload it to your bank.
