We have an issue where the Billing / Shipping addresses on an order will automatically remove the leading 0 from a zip code. For example:
Danbury, Connecticut, 06811 becomes
Danbury, Connecticut, 6811
This causes some validation errors with UPS and other shipping API's as it is trying to validate
6811 as a zip code.
So how can we make it so billing / shipping saves the full zip code with a leading zero?
