Use Cases


Pinpoint Target Consumers with Precision

ZIP+4s represent a smaller set of households, which means they can be used to narrow results for direct mail efforts.

Learn Where Customers Live for Better Marketing Analysis

ZIP+4s represent a smaller set of households, which means they can be used to narrow results for direct mail efforts. Because our database includes centroids, businesses can use them for marketing research to discover where their customers live. ZIP+4s give you a clear idea of how far people are willing to travel.

Indispensable for Geocoding

Businesses use ZIP+4s as a cost-effective and efficient source for geocoding millions of addresses, based on their ZIP+4s, to accurate locations.

"With the integration of the Maponics ZIP+4 Database, the results are incredibly reliable and precise, arming our customers with the ability to accurately target their marketing efforts using our integrated radius and donut-radius select capabilities. The ZIP+4 match rate to precise Latitude and Longitude coordinate using our CASS Certified® engine with Maponics ZIP+4 Database is simply astounding. "

Features & Benefits


Quarterly updates are critical for ZIP+4's - ZIP+4's are dynamic; about 100,000 additions and deletions occur every three months. Maponics releases updated ZIP+4's every quarter so our customers can keep current with the latest postal changes.

Not just repackaged from the USPS - ZIP+4's are initially represented by the US Postal Service as a ZIP+4 low value and a ZIP+4 high value – for example, 20001-0001 to 20001-0486. Maponics expands these to represent the individual ZIP+4 values included within the ZIP+4 range
