Mailing Resources


A virtual library of postal information and tools designed for U.S. Postal Service customers, business mailers, and employees.


Provide information to customers when there are occurrences that may affect your mailings and deliveries. This includes storms, equipment and system issues.


The BCG is used to retrieve information about your mailing as well as submit your mailings electronically. ACS returns can also be viewed on the BCG.


CASS, or “Coding Accuracy Support System” standardizes addresses so that they conform with USPS guidelines for street address abbreviations, city name abbreviations, and zip codes. It also assigns zip+4 extended zip codes, carrier route information, and Line-Of-Travel information. All address records in an Interlink Circulation list are CASS processed as part of the list servicing that happens during the postal sort.

To check individual addresses instantly, try our online CASS Lookup, updated monthly with the latest address information directly from the USPS.

I'm proud to now be able to offer Interlink's True Newspaper Mail service to ANY newspaper that uses the USPS for delivery. It's cloud based, so there are no hardware requirements or time consuming downloads for updates. Just upload your list, and our pre-sort handles the rest. Whatever Circulation software you currently use, if you deliver papers through the mail, then True Newspaper Mail is for you!

One of my favorite parts of our new circulation software was the inclusion of True Newspaper Mail. True Newspaper Mail works so easily, accurately, and is simple to adapt to our many different publications. Better still is the staff at Interlink! They are very responsive to specific needs and making sure the software is always running smoothly. Having worked with other brands of postal software, True Newspaper Mail is at the top of my list!
