Hi HH20211111.
Welcome to the QuickBooks Community where all our members get together to ask questions and help one another out. Great job with getting started on creating your own QuickBooks Online Accountant account. I'd be happy to help you get it up and running.
If your QuickBooks Online Accountant account is asking for you to enter a zip code than it sounds like you may have made it using the American website. As the Canadian and American versions are different you'd need to create a new account for the Canadian one. This includes using a different email as well as you can't use the same email for two accountant accounts. You can follow this link to create the Canadian version whenever you're ready.
If you have any questions let us know and we'd be happy to help.
