Chapter 7 Bar Codes

Check Digit

The modulo-10 check digit is automatically calculated and inserted in the bar code symbol. The check digit verifies accurate scanning. The number system character is included in the check digit algorithm.

FIM

The FIM (Facing Identification Mark) bar code structure is shown in Figure 13 and described on the following pages. The left boundary must begin 3 inches from the right edge of the mail piece. The right-most bar must be 2 inches ± 1/ 8-inch from the right edge of the mail piece. Bars are 5/8-inch ± 1/8-inch tall; the top of the bars must be no lower than 1/8-inch from the top edge of the mail piece (and may touch the top edge of the mail piece). The bar code baseline must be within 1/8-inch from the bottom edge of the clear zone.
