Tech Support Q&A: How do I CASS certify my mailing?

Q:     How do I Cass certify my mailing?

A:     USPS requires CASS Certification at least every 90 Days for updated mailing information (County, Route, Zip+4, eLOT, and WS values).

You may CASS process your list in either of the following ways:

1. Select “Service List…” from the “File” menu. This will send a copy of your list to Interlink for processing.

2. When you close an issue of your publication, there is a box on the close issue screen labeled “Service list before closing”. By default, this box should be checked and if so, your list will be automatically CASS processed immediately before the issue is closed.

After your list has been serviced (which includes CASS processing), we recommend printing a CASS Error Report, correcting any addresses that show up, then servicing your list again.  When the list is returned, an updated copy of the 3553 CASS Report will be added to your file.  To print the one page report, go to Print Reports, choose the 3553 CASS report and click on Print all. Be sure to sign and date the report in the space provided.

Interlink receives regular updates from USPS at least once every 90 days.

*If the Customer’s local Post Office has made updates recently to subscribers’ addresses in the USPS Systems, the Interlink Subscriber’s record may not be updated in the system for up to 90 days from that date.
