🚚 Operational Shifts

• Postal carriers will be leaving facilities earlier to accommodate longer delivery routes, especially in rural areas.
• Saturdays and the day before holidays will no longer count as transit days for packages.

🧾 ZIP Code Refinement

📦 Smart Moves Parcel Shippers Should Do

Parcel shippers need to take steps to adapt and stay competitive. Here’s how to prepare for the changes and navigate the evolving delivery landscape:

1. Audit Your Shipping Profile
   Review your volume, destinations, delivery times, and carrier mix. Identify which packages may be affected by longer USPS transit times.
2. Use the USPS Service Standards Tools
   Forecast delivery impacts using the Service Standards Lookup and Interactive Map. Focus especially on First-Class and Marketing Mail.
3. Adjust Customer Promises
   Update shipping cutoffs, estimated delivery windows, and return policies to reflect the new standards. Communicate changes proactively to customers.
4. Diversify Carrier Strategy
   Explore regional and private carriers to supplement USPS. Use multi-carrier shipping software to route packages for optimal speed and cost.
5. Optimize Fulfillment Locations
   Consider multiple fulfillment centers or 3PL partners near key markets to reduce long-zone shipping delays.
6. Review Package Types and Mail Classes
   USPS changes may affect how different sizes and classes are handled. Evaluate options like USPS Ground Advantage or Priority Mail.
7. Plan for Transit Delays on Saturdays and Holidays
   USPS will no longer count Saturdays or pre-holiday days as transit days. Adjust timelines and customer communications accordingly.
8. Train Your Team
   Educate your warehouse, operations, and support staff on the changes. Set up processes for managing delayed or misrouted shipments.
9. Monitor Metrics and Returns Closely
   Track delivery performance, return rates, and customer satisfaction to stay agile and informed.
10. Work with a Logistics Consultant
    Partner with experts like ebb Logistics to build a custom shipping strategy, streamline operations, and stay competitive in a changing market.

By staying proactive and strategic, parcel shippers can not only adapt to USPS changes but also uncover new efficiencies and growth opportunities.
