Your ZIP+4 is a basic five-digit code with four digits added as an extra identifier. It helps 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, or a post office box. ZIP+4 Codes improve the mail sorting and delivery process - the increased level of accuracy helps speed up delivery time, decrease the chance of delivery errors, and qualify mailers for bulk mailing discounts.
