National Bank Cheque Positive Pay file support

Generate the fixed-width ISSUE file for National Bank’s Cheque Positive Pay service from a cheque list that you review first.

What this generator supports

  • Normal issued-cheque records only; VOID, CANCEL, STOP, DELETE, and REMOVE_STOP are blocked.
  • CAD or USD reconciliation-account profiles. Currency belongs to the enrolled profile and is not written into the record.
  • Windows-1252 output with 346-byte records, CRLF separators, a final CRLF, and no header, trailer, or BOM.
  • The deterministic filename CS031XXXXXXX.TXT, using your seven-digit National Bank reconciliation account.

Before you generate

Use the seven-digit reconciliation account assigned to your enrolled Cheque Positive Pay service. Check the detected cheque count, total where available, dates, amounts, numbers, and payee examples before payment. The tool refuses values it cannot encode exactly and never truncates a payee.

After download

Upload the file through National Bank’s Cheque Positive Pay service. Before relying on the issued records, confirm that the bank reports the file accepted and that its accepted issued-item count matches the count shown in your local review.
