Cant create an account in Canada

Love Nordstrom and would like to order online for shipping to Canada. Unfortunately I cant, because I cant create an account. This is all because of a restriction on the Zip/postal code field that limits it to only numbers on the keyboard, and postal codes have both numbers and letters.

Please fix this to allow entering both numbers and letters.
