I am working with a freight carrier who can only provide the Canadian postal codes where a surcharges is applicable in ranges. I need to break them out into individual codes to compare them to another carrier. The Canadian postal code is a six-character string that forms part of a postal address in Canada. The postal codes are alphanumeric. They are in the format A1A1A1, where A is a letter and 1 is a digit. Any help on this would be appreciated.
