Presort Verification  
Verify sortation to qualify for automation rates.
The MERLIN™ program can verify the sortation composition of discounted mailings. It examines tray labels, package sortation, and container sortation according to Domestic Mail Manual requirements for First-Class Mail®, USPS Marketing Mail™, and Periodicals. If the sample tested by MERLIN yields a score greater than 95 percent or higher, the mailing qualifies for the rates claimed.
