What the NCOALink® Process Delivers
Each list processed through EZ24x7’s NCOALink® service includes standardized and enhanced postal data to ensure complete deliverability:
Original Input Record – The unaltered address as originally submitted.
Standardized Address – Updated with correct ZIP+4®, Delivery Point Code (DPC), and other postal data through CASS™ processing.
New Forwarding Address – For matched records, a standardized new address with Intelligent Mail® barcode and USPS return codes.
Move Details – Includes the move effective date, matched name and address, and move type (Individual, Family, or Business).
Unmatched Addresses – Retained with all standard CASS™ enhancements and return codes.
Additional Data – Includes Urbanization name (when applicable) and Carrier Route information for all updated records.
Processing Summary Report (PSR)
Every NCOALink® job returns a Processing Summary Report that includes:
The specific list name or identifier.
Match statistics and counts by return code.
USPS compliance verification for Move Update requirements.
This PSR acts as your substantiation of NCOALink® compliance — essential for USPS audit readiness.
