CASS™ Processing
The Coding Accuracy Support System (CASS™) is a United States Postal Service® (USPS® ) program that certifies the accuracy of address validation software. To qualify for certain postal discounts you must use software that is CASS Certified™ to assign ZIP Code™, ZIP + 4® codes, and delivery point barcodes to mail.
Makers of address validation software must pass a test designed by the USPS in order to have their software designated as CASS Certified. CASS Certified software must pass tests of accuracy in the following areas:
- Five-digit coding
- ZIP + 4/delivery point (DP) coding
- Carrier route coding
- Delivery Point Validation (DPV™ )
- Locatable Address Conversion System (LACSLink™ )
- Enhanced Line of Travel (eLOT™ )
- Residential Delivery Indicator (RDI™ )
When you use a CASS Certified product, you are assured of the following minimum levels of accuracy:
| Certification Level | Required Accuracy Level |
|---|---|
| ZIP | 98.5% |
| Carrier Route | 98.5% |
| ZIP+4 | 98.5% |
| Delivery Point Barcode | 100% |
| eLOT | 100% |
| Perfect Addresses | 100% |
EngageOne™ Enrichment is not a CASS Certified product, but it can be used with CASS Certified software to standardize addresses in print streams to USPS® requirements. To do this, EngageOne™ Enrichment extracts the addresses from the documents and passes them to a CASS Certified address cleansing program. Address cleansing programs verify addresses and return the complete postal codes used to build the IMB™ barcode.
You can use Finalist to standardize addresses.
