Effective April 5, 2010, the Postal Service™ will revise Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM®) 507.13.4.4.h2, which gives mailers the option to change the label format by reducing the required clearance space between the Parcel Return Service Mailer Identification (ID) characters and the edges of the printed box from 3/16 inch to 1/16 inch. This revision provides customers the option to increase the mailer ID font size within the printed box and provide better visibility of the mailer ID during processing.
