Verification Email

Be sure the code is not ending up in your email's spam/junk folder or another email address you have.   See this FAQ on some tips, which also includes info on how you can change the email address in your Account Profile settings, if you wish to use another email address.

FAQ: What if I'm having trouble with my filing verification code?

Or it could be this.   Maybe your email address was never verified when you set up your account.   While you are in your Intuit Account Settings, go to "Sign In and Security" and see if the email address shown in your Intuit Account has ever been verified.   If it shows it is "not verified", you can verify it by clicking the link and following the instructions.  Then see if a link (or possibly a code) is emailed to that email address to verify it, and then you may have to log back in again.  Then your email address should be verified.

If nothing above is helpful, please phone Customer Support.

Support hours are 5AM-9PM Pacific every day this time of year during filing season.
