What is a Mail Carrier Route?

Zip Codes are broken down into mail carrier routes. A carrier route refers to the daily deliveries of a mail carrier. A route includes all the residential and commercial deliveries within the boundaries of the route. The average carrier route has 300 to 600 daily deliveries.

The mail carrier route map below shows how carrier routes are defined. Streets are clearly shown making it easy to target specific neighborhoods. A mailing using a mail carrier route list can be mailed at the lowest standard postage rate.

Mail Carrier Routes Are Defined with a 5 Digit Code
