Postage savings achievable with ZP4

Instead of paying a full 42¢ per letter (as of May 12, 2008), 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 42¢, or $84. But mailing 200 barcoded pieces with ZIP + 4® codes as "standard automation" mail at 22.5¢ per piece costs $45, for a total savings of $39! 
Presort  Regular  Nonprofit
-------  -------  ---------
5-digit   22.5¢    12.7¢
3-digit   24.1¢    14.3¢
AADC      24.4¢    14.6¢
Mixed     25.7¢    15.9¢
ECR       23.4¢    15.9¢

The above tables list only a few of the available postal discounts. For example, submitting your bulk mail to a Sectional Center Facility Post Office™ lowers the rate to only 18.3¢ per piece for 5-digit presorted pieces and only 8.5¢ for nonprofit mail. 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. The eLOT® CD-ROM contains all the software you need for sorting and printing "standard automation" letters or postcards for any address lists processed with CASS software.
