June 5, 2016Will the 4 digits added to zip code (ZipCode+4) change where will the shipment go ?
If the shipping service is adding the +4, keep it. The plus four is a more precise part of a ZIP Code’s service area; a subset of addresses on a delivery route. Just helps with sorting the mail in a more efficient order. ZIP Code “geography” is interesting. First three numbers direct mail to a specific sorting facility, fourth and fifth digits are representative of specific areas served by that sorting facility. And the +4 is “four additional digits to identify a geographic segment within the five-digit delivery area, such as a city block, a group of apartments, an individual high-volume receiver of mail, a post office box, or any other unit that could use an extra identifier to aid in efficient mail sorting and delivery. “ - from Wikipedia.
