Presort/printing software for bulk mail discounts
plus eLOT® data on CD-ROM all for $19

The optional eLOT CD-ROM for ZP4 includes two major systems: (1) presort/printing software for bulk mail, and (2) the eLOT database, both of which are described below. An eLOT disc is typically purchased at the same time as a ZP4 disc. ZP4 can be purchased without an eLOT disc, but purchasing an eLOT disc requires purchasing the corresponding ZP4 disc (eLOT lookups require ZP4). Note that the Standard Automation presort/printing software and the eLOT database are separate independent systems that happen to be distributed on the same CD-ROM: Standard Automation mail preparation doesn't use eLOT data.



Presort/printing for bulk mail

The eLOT CD-ROM contains all the software you need for sorting and printing a CASS™-processed mailing list as Standard Automation letters or postcards or Enhanced Carrier Route Automation basic letters, allowing you to send mail at discount postage rates. You can print barcoded mail, generate the required presort qualification report, tray labels, and necessary postage statement (form 3602).



Enhanced line of travel

The eLOT database contains a sequence number and an ascending-or-descending code for every combination of ZIP + 4® code and two-digit delivery point, to allow mail to be sorted in approximate carrier-casing order and thereby qualify for certain enhanced carrier route presort postage discounts.

The eLOT database occupies approximately 210 megabytes. An eLOT CD-ROM is released every month, for use with the corresponding ZP4 edition. Once eLOT data is installed, ZP4 is able to automatically determine the proper line of travel data for addresses.

eLOT lookups may not be performed after the two-month expiration date of the eLOT database. Enhanced Carrier Route Automation Letters without line of travel are actually cheaper than Enhanced Carrier Route Letters using line of travel, but automation is limited to 3.5 ounces and certain ZIP Code™ numbers and requires a barcode. Review the Postal Service™ preparation requirements and costs carefully before deciding you need line of travel data. Note that the Standard Automation presort software on the eLOT disc does not sort mail by line of travel numbers.
