Our USPS CASS Certified™ address validation service matches and corrects mailing addresses using the latest USPS and proprietary data sets available, ensuring your mailing records are always accurate and up-to-date. The service helps improve internal mail processes and ensures cost-saving delivery rates by verifying and standardizing addresses, while flagging for vacancy, returned mail, and general delivery addresses. With the API’s sub-second response times, the service can be used in real-time to help customers and leads correct errors at the time of entry, increasing customer satisfaction and reducing customer service inquiries.
Our industry-leading, GetBestMatches operation combines Delivery Point Validation (DPV) to verify an address is deliverable, Residential Delivery Indicator (RDI) to identify residential or business, and SuiteLink (SLK) to add secondary suite information for businesses, into one robust API call to our USPS CASS Certified database engine.
