Why Is My Verification Code Invalid?

Troubleshooting steps when your verification code does not work

Updated over a month ago

You have followed the steps to Using Email Verification to Sign In and received a verification code to your inbox. However, there appears to be a problem with the code.

Please note that verification codes are single use and only valid for 30 minutes from your login attempt.

If you are experiencing issues when trying to use the verification code, please try the following to assist with logging in:

1. Delete all DTA login emails in your inbox from previous login attempts

2. Go to dta.com.au

3. Click on 'Sign In' in the top left-hand corner

Please delete your browsing history and attempt to login again.

Helpful Tips for Using Verification Codes:

  • Allow a few minutes for the verification code email to arrive in your inbox

  • Check your spam/junk folder if the email has not arrived

  • Verification codes are valid for one-time access - a new code is required for each login

  • Avoid requesting multiple codes, as this can lead to your account being locked. Each time ‘request a new code’ is used, the previous code becomes invalid. Only the most recent code will be valid
