Returning Charges even wrong postal code

[dotnetclassic]

I am trying to get providers and rates with wrong destination postal code and it still getting rates

`var origin = new Address("", "", "72204", "US");

var destination = new Address("", "", "11111111111111111111111111", "US"); // US Address`

See result it should not give rates with wrong postal code.
