Wisco Develops Rate Tester Tool for Mailers

Wisco, Tullahoma, Tenn., is offering a free tool to help correctly classify mail pieces under the U.S. Postal Service’s new shape-based pricing guidelines, which increased postage for letter-size pieces and redefined the size parameters for letters, flats and parcels. Postal guidelines are drawn to scale directly on the Wisco rate tester, allowing users to lay mail pieces on the grid to determine classification.
