 ZIP+4's are the designation by the United States Postal Service (USPS) for a nine-digit ZIP Code structure. The USPS added the 4-digit extension to the standard 5-digit ZIP Code in the 1980s to facilitate mail sorting and delivery. The 4-digit extension represents a geographic segment within the larger ZIP Code, such as one side of a city block, a group of apartments, a single large building or even one floor of a skyscraper. By contrast, ZIP Codes represent over 7,400 people each.

Customer Segmentation

The benefit of using ZIP+4 codes for marketing intelligence is that they can provide just the right amount of granularity when seeking to effectively direct market to customers. Depending on marketing needs, a ZIP Code can be too large to tell companies enough about their customers. And information about each individual consumer is time-consuming to process and difficult to obtain. Here's an example of how a large home improvement chain would use ZIP+4 data for direct marketing and gaining marketing intelligence... A home improvement chain retailer has a list of thousands of member addresses across the country, and needs to quickly and efficiently associate those addresses down to precise units of geographies for a targeted direct mail campaign. The ZIP Codes help, but not to the level of precision the retailer requires. With ZIP+4 centroids that contain address ranges, the retailer can quickly assign addresses directly to ZIP+4 codes along with the associated latitude and longitudes, all powerful tools in launching a direct mail campaign. After successfully assigning ZIP+4 codes to their members' addresses, the retailer can now cost-effectively segment and direct market to their members. Having the ZIP+4 codes assigned to addresses will also allow the retailer to use powerful demographic and analytic data to gain greater intelligence about their customers and their customers'  behavior.
