CASS Certification

Lower Your Postage Bill and Reduce Undeliverable Mail

You can improve the responsiveness of your direct mail campaign by updating your in-house mailing list with CASS Certification/DPV. Just send us your file in any of our accepted output formats and we’ll process it through the Coding Accuracy Support System (sometimes referred to as “Zip+4 appending”). You’ll lower postage costs and reduce undeliverable mail! The USPS requires CASS certification every 6 months to qualify for barcode discounted mailings.

Here is what CASS does:

• Validates address information at the exact delivery point to determine if mail peice is deliverable
• Corrects spelling errors in street names, cities and state abbreviations
• Corrects Zip Code and appends Zip+4 and Delivery Point Barcode data
• Adds or standardizes directions (North, South, East, West, etc.)
• Adds or standardizes suffixes (Avenue, Street, Boulevard, etc.)
• Qualifies mailings for reduced postage rates
• Reduces undeliverable mail with more accurate addresses
• Improves duplicate identification
• Error report identifies potentially undeliverable addresses

Examples:

LIMITATIONS: Cass certification will not make your list 100% deliverable! It does not verify that the name (or company) associated with your address is correct and therefore deliverable. See NCOA for further options to clean your list.
