Postage savings achievable with ZP4

Instead of paying a full 44¢ per letter (as of June 6, 2011), using barcodes generated with CASS™ software lets you qualify for bulk rates as shown below. For example, mailing 200 pieces of First-Class Mail® cost 200 x 44¢, or $88, but mailing 200 barcoded pieces with ZIP + 4® codes as "standard automation" mail at 23.7¢ per piece (in a 5-digit presort) costs $47.40, for a total savings of $40.60!

Bulk discounts require certain quantity and sorting preparations and permits. See the Postal Service™ Domestic Mail Manual or your local Postmaster for complete details and regulations.
