eLOT®

Speak to an Expert

What is eLOT®?

The simple definition of eLOT® is that it’s a mail sorting product developed by the United States Postal Service (USPS). It stands for Enhanced Line of Travel, and gives mailers the ability to sort their mailings in approximate carrier-casing sequence.

What Does That Mean?

Insert meme of confused minion here, right? For anyone who isn’t fluent in mail-talk, that basically means that eLOT® is a product that helps to presort your mail, improving delivery accuracy and increasing mailing rate discounts. eLOT® takes the guesswork out of mail delivery by using a sequence of numbers and codes to indicate exact mailing addresses.

I’m a USPS eLOT® Pro

If you’re already fluent in the mail-bending ways of the USPS, that’s great! We’ve got more details for you. eLOT® has a sequence number field and an ascending or descending code. The sequence number indicates the first delivery occurrence made within a carrier route. The ascending or descending code indicates the delivery order within the sequence number.

The History of eLOT®

Don’t worry, we promise this won’t be as boring as it was in high school — but it will be just as educational! eLOT® is not an entirely new product, but rather an expansion of an existing USPS product: Line of Travel (LOT®).

LOT® and eLOT®: What’s the Difference?

LOT® narrows down a mail carrier’s delivery route to the block face level (i.e., the Zip+4 code) and identifies whether an address is on the odd or even side of a street. eLOT® narrows down this route even further by identifying the address at a delivery point level (i.e., the house number).
