Postal Infusion & Destination Delivery Unit (DDU) Services

The Cost-saving Final Mile Solution for Retailers

Use the U.S. Postal System to your advantage. We’ll pinpoint where your delivery needs and existing USPS routes align—slashing delivery costs and speeding up delivery times.

Speed & Savings

For today’s retail customers, delivery speed is a major differentiator and cost-savings a must. Postal infusion allows our retail partners to give your customers the speed they crave while preserving your bottom line.
Speed: Fast-track your packages through the final mile supply chain. By using preexisting USPS routes, retailers can drastically reduce expected delivery times for their customers.
Cost Savings: Not only does the efficiency of postal infusion save retailers on fuel costs, it often also generates discounts from post offices.

How it Works

For retailers shipping high volumes of small goods—like clothes, automotive parts, vitamins, or pet food—this hybrid private carrier-US Postal Service final mile delivery solution is a win-win-win

Identify & Partner

The retailer partners with a national small package logistics provider that has nearby high-speed, round-the-clock sorting operations. USPack can help you identify the best provider in your area.

Sort

Depending on preference, the national provider or USPack picks up parcels from the retailer’s warehouses or stores and delivers them to the sorting facility for overnight sorting by zip code

Deliver to USPS

USPack drivers pick up at the sorting facility as early as 5 AM and bring sorted packages to the respective post offices within a 100-mile radius, arriving before USPS begins that day’s deliveries.
