What type of markings would typically NOT be found with Enhanced Carrier Route?

In the context of mail processing and delivery, Enhanced Carrier Route (ECR) is designed to support efficient mail delivery by utilizing specific markings that enhance the automation of sorting and delivery. The type of markings that would typically not be associated with Enhanced Carrier Route are automation markings.

Automation markings are generally used to indicate that a mail piece qualifies for automated processing and might feature specific barcodes that improve the efficiency of sorting. However, in the case of Enhanced Carrier Route, mail is primarily categorized based on delivery routes and is enhanced by specific indicators designed to facilitate delivery to residential or business addresses along those routes, rather than relying exclusively on automation.

Therefore, the other options — barcoded addresses, route delivery points, and residential delivery indicators — are integral parts of the Enhanced Carrier Route schema. Barcoded addresses help in tracking and managing mail flow, route delivery points specify particular locations for delivery within a route, and residential delivery indicators clarify the nature of the addresses being served. In contrast, automation markings are not a characteristic found within this specific delivery framework, making them the answer that does not align with the Enhanced Carrier Route specifications.
