What is the minimum number of pieces required for ECRWSH (Enhanced Carrier Route Walking Sequence High-Density)?

The minimum number of pieces required for Enhanced Carrier Route Walking Sequence High-Density (ECRWSH) is 125 pieces per route. This requirement is based on the Postal Service's guidelines for ECRWSH eligibility, which aims to optimize the efficiency of mail delivery by consolidating mail into high-density routes. ECRWSH typically serves densely populated areas where there are at least 125 pieces of mail that can be prepared for delivery on a single carrier route, allowing for streamlined processing and delivery. Meeting this minimum ensures that the mail can be sorted and sequenced in a way that maximizes efficiency, reduces handling time, and ultimately, enhances delivery performance.
