The USPS performs the following types of mailing certifications:
| Certification Type | Description |
|---|---|
| CASS Certification | The USPS uses CASS certification to certify postal coding software packages. This type of certification applies to the Finalist software. |
| Vendor Certification | The software vendor certifies their postal coding software using the Stage 1 and Stage 2 tests. Precisely CASS-certifies every release of Finalist before any release of the software to customers. |
| Client Certification | A customer may certify their Finalist integration if they wish. If you decide to certify your Finalist integration, Precisely is not responsible for support of your USPS certification process and audits. Note: Stage test certifications require the use of special static databases. Please contact Technical Support to obtain these databases if you are trying to certify using Finalist.
|
| Mailing List Certification | A mailer can certify a mailing list by processing address files through CASS-certified software (such as Finalist) every six months. This procedure is required for all mailings receiving postal discounts. The USPS requires the USPS Form 3553 (CASS Summary Report) as proof that a mailing is CASS-certified. For more information on the USPS Form 3553 (CASS Summary Report), refer to USPS Form 3553 (CASS Summary Report). |
| PAVE Certification | The USPS uses PAVE certification to certify presort software packages. |
