Sorry for the inconvenience. Looking up to your postal code, it appears fine; however, try to fill it again by completely erasing the data in the postal code dialogue box, the reason being, sometimes there are hidden characters such as spaces. Originally, the code must include 6 characters only, no spaces, and special characters.
Another way is, by changing the format of the data. For example, B4A 0J8 / B4A0J8.
For more clarification, read our FAQ's - Invalid Characters when trying to use NETFILE
Thanks
