In order to geocode to the ZIP+4 (9-digit) level, you must first validate your
address data, to append the ZIP+4 postal code. Validating your address data to
the delivery point level using a CASS Certified™
address
cleansing solution will
ensure that every address meets USPS® specifications.
Geocoding to the ZIP+4 level displays the address typically within a radius of
nine households.
Uses of this level of geocoding accuracy include:
• Demographics and customer segmentation
• Target marketing
