Thanks for joining us on TD Helps, Lily.
If the debit card you're using is for TD Bank, America's Most Convenient Bank, the Billing Zip Code would be the Zip Code for your physical address which we have on file. We do notice that you're writing in from Canada, if you'd like, we invite you to ask this question to our friends in the North. You may do so by clicking here: http://bit.ly/1kD3iFr or you may call the EasyLine at 866-222-3456 for assistance.
