Wrong Account Number
On a Cheque?

Writing a cheque requires intense focus. A single digit error in the account number can lead to a payment going to the wrong person or the cheque being rejected. Here is your emergency guide on what to do.

Rule Number One

Never use white-out or cross out an error on a cheque. Any alteration to the MICR line (the numbers at the bottom) or the payee details will result in an automatic rejection by bank scanning systems.

Scenario A: You caught the error before giving it to someone

This is the best-case scenario. If the cheque is still in your possession:

  • Void the cheque: Write 'VOID' in large letters across the front.
  • Destroy the cheque: Shred it to prevent anyone from seeing your bank details.
  • Start over: Write a fresh cheque with the correct details.

Scenario B: You already handed over the cheque

If the cheque is already out of your hands, you must act fast:

1. Call Your Bank

Request a "Stop Payment Order". You will need to provide the cheque number, amount, and the date it was written.

2. Notify the Recipient

Tell them the cheque has an error and you have stopped payment. This prevents them from trying to deposit it and facing bank fees themselves.

How to prevent this in the future?

Always double-check the recipient's details. If you are writing a cheque for a business, ask for their exact legal name and account number in writing.

Pro Tip

Before signing, read the cheque back to yourself. Ensure the numerical amount matches the words, the date is correct, and the account number (if applicable in the memo) is accurate.
