HINGTON -- A postal official said yesterday the 4-state barcode will be required in order to receive automation discounts in 2009.

The announcement, which was made at the quarterly Mailers' Technical Advisory Committee meeting here by Charles E. Bravo, senior vice president, intelligent mail and address quality, for the U.S. Postal Service, was a surprise to many attendees. Until now the four-state barcode was to be used strictly on a voluntary basis.
