ECR letters that are not automation-compatible and barcoded (DMM 201.3.0) are mailable at the flat-size prices (DMM 243.6). Mailers may not pay ECR flat prices and claim the DDU discount for letter-size pieces.

For pieces weighing more than 3.3 ounces, each piece is subject to both a per piece price and a per pound price. Multiply the number of pieces in the mailing by per piece price. Multiply the number of pounds of the mailing by per pound price. Add both totals.

Per piece price for ECR letters and automation letters that weigh more than 3.3 ounces but less than (or equal to) 3.5 ounces includes a discount that equals the applicable flat-size price (3.3 ounces or less) minus the applicable letter piece price (3.3 ounces or less).
