Where to Find Your Bankwest Biller Code

You can find the Biller Code on your Bankwest paper bill, usually near the BPAY logo. It may be located:

  • At the bottom of the first page of the bill;
  • On the back of the bill;
  • In the section with the detachable payment slip.

Note that the Biller Code is a numeric identifier indicating where the funds should be sent. Each recipient has a unique code, so it must be entered correctly.

How to Use the Biller Code in Bankwest Online Banking

To pay a bill via BPAY in Bankwest online banking, follow these steps:

  1. Log in to your Bankwest online banking account.
  2. Go to Payments & Transfers and select Make a Payment.
  3. Choose BPAY as the payment method.
  4. Enter the Biller Code shown on your bill.
  5. Select the payee from the dropdown list or add a new one if it is not listed.
  6. Enter your Customer Reference Number (CRN), also shown on the bill.
  7. Specify the payment amount and date.
  8. Confirm the payment and save the receipt for your records.

If you have difficulty finding your Biller Code or CRN, contact your service provider or Bankwest support for assistance.

Pro-Tip: Save Bankwest as a "Saved Biller" or "Favourite" in your banking app after your first successful transaction. This efficiency hack eliminates the need to manually enter the 9100 code and your 16-digit card number every month, drastically reducing the risk of typos and speeding up future payments.

Troubleshooting Common Payment Pain Points

Even with the correct details, you might encounter technical friction. Here is how to resolve the three most common payment issues:

  • MFA (Multi-Factor Authentication) Delays: If your SMS OTP does not arrive when authorizing the BPAY payment, do not repeatedly click the Resend button, as this overrides previous codes. Wait a full 60 seconds, check your cellular connection, or switch to your banking app's in-built VIP token generator.
  • Browser Session Errors: Getting unexpectedly logged out while entering the Bankwest BPAY code is typically caused by an expired session timer or corrupted browser cache. Clear your browser cookies or open a new "Incognito Mode" window to complete the payment smoothly.
  • Locked Bank ID: If you enter the wrong password too many times trying to access your sending bank, your Client ID will lock for security purposes. You must reset your access via the Forgot Password link using your registered email and mobile number before you can initiate the BPAY transfer.

Frequently Asked Questions

How long does a BPAY payment to Bankwest take to clear?

Most BPAY payments take 1 to 2 business days to process. If you authorize the payment before your sending bank's daily cut-off time (usually 6:00 PM AEST on a business day), the funds will generally be credited to your Bankwest account by the following business day.

Can I use a different reference number for my Bankwest BPAY payment?

No. You must strictly use your 16-digit Bankwest credit card number as the Customer Reference Number. Using any other number or adding spaces will result in the payment failing, being rejected, or misallocated to the wrong account.

Bankwest provides a convenient and secure way to pay bills using BPAY. To complete a payment successfully, you need to enter the unique Biller Code and your Customer Reference Number (CRN), which ensure that the payment is directed to the correct recipient and account.
