Address Hygiene & Data Quality
Clean data, fewer returns — CASS-certified address standardization, 48-month NCOA move-update processing, and targeted suppression to keep your mail on target.
Key Capabilities
CASS Certification
Addresses are validated and standardized against the USPS Coding Accuracy Support System database, correcting ZIP+4 codes, delivery points, and formatting to meet mailing standards.
NCOA Processing (48-Month)
National Change of Address processing matches your file against 48 months of USPS move data, updating addresses for individuals and businesses that have filed forwarding requests.
Duplicate Detection
Sophisticated matching algorithms identify and flag duplicate records across your file — including fuzzy matches on name, address, and household — to eliminate redundant mailings.
Deceased Suppression
Records are matched against national deceased registries to remove individuals who are no longer reachable, improving accuracy and demonstrating responsible data stewardship.
Prison Suppression
Suppress addresses associated with federal and state correctional facilities to avoid mailing to individuals who cannot act on your communications.
Address Standardization
Non-standard address formats are corrected to USPS Publication 28 standards — proper abbreviations, directionals, unit designators, and line placement — for consistent, deliverable output.
