About

One in five addresses contains errors that can result in late or undeliverable mail and shipments. Our address validation US service verifies and corrects addresses to ZIP+4, ensuring addresses are valid and deliverable, avoiding costly shipping and customer service issues. Encompassing multiple authoritative sources, our validation engine leverages over 160 million USPS addresses, as well as an additional 15 million non-postal addresses to validate and correct US mailing and shipping addresses with unparalleled precision. Our engine surpasses the stringent requirements of the USPS, exceeding their CASS (Coding Accuracy Support System) accuracy standards. Our software focuses on address precision, significantly mitigating costs associated with undeliverable, lost, or returned mail. Whether shipping products or mailing invoices, Service Objects Address Validation ensures delivery while avoiding costly address correction fees from the USPS and third-party shippers.
