eLOT® (Enhanced Line of Travel) was developed by the USPS to allow mailers to sort their mailings in approximate carrier-casing sequence.
To aid in mail sorting, eLOT® contains a sequence number field and either an ascending or descending code. The eLOT® sequence number indicates the first occurrence of delivery made to the add-on range within the carrier route, and the ascending/descending code indicates the approximate delivery order within the sequence number. eLOT® processing may be used by mailers to qualify for enhanced carrier route presort discounts.
