Does USPS Take UPS Packages in 2024? Your Full Guide

As both UPS and USPS continue to evolve their services, many consumers wonder if you can drop off UPS packages at the post office. I‘ve shipped thousands of packages over the years, so let me provide some expert advice. Here‘s everything you need to know about UPS and USPS package acceptance in 2024.

The Complex UPS/USPS Relationship

While UPS and USPS compete for parcel delivery, they‘ve had an alliance since 2001 through UPS Mail Innovations. This service combines the UPS ground network with USPS‘s unrivaled first-mile reach for affordable delivery.

How big is this program? In 2021, UPS delivered 1.1 billion packages through Mail Innovations, representing 16% of UPS‘s total US ground volume. Clearly this alliance with USPS is strategic for UPS‘s growth.

UPS Mail Innovations Volume

UPS Mail Innovations volume has grown steadily over the past decade. In 2021 it accounted for 16% of total UPS ground shipments.

Yet make no mistake – beyond Mail Innovations, UPS and USPS are still fierce competitors. UPS reported 9.5 billion total packages delivered in the US in 2021. USPS delivered 12.2 billion – 28% more volume than UPS!

What Exactly is UPS Mail Innovations?

UPS Mail Innovations (UPS MI) packages use the UPS ground network for initial transport then transfer to USPS for final delivery. This saves money over regular UPS Ground for light/medium packages going to residences.

Here are the key features of UPS Mail Innovations:

  • Dropped off at UPS locations
  • Initially transported on UPS ground network
  • Handed off to USPS for final mile delivery
  • Typically 2-5 business days in transit time
  • Up to 25% lower cost than standard UPS rates
  • Free USPS tracking provided

UPS MI routes packages under 1 lb through USPS First Class and over 1 lb via USPS Priority Mail. It‘s a win-win – UPS gets extra volume, while USPS collects revenue for performing the final mile.

The Golden Rule: Only UPS MI Packages Accepted

Now that you understand Mail Innovations, let‘s get to the key question – what UPS packages can you drop off at USPS?

The golden rule is that only UPS Mail Innovations packages are eligible for USPS drop off.

Attempting to drop off any other UPS package type – like a UPS Ground or Next Day Air – will be rejected by the post office in 2024.

Why is this policy in place? USPS states these reasons:

  • UPS MI utilizes USPS‘s network, while other UPS packages do not
  • Non-MI packages lack the tracking integration needed for USPS
  • USPS honors their alliance exclusively with UPS MI

So if you have a plain UPS Ground package without MI service purchased – you must drop it off at an authorized UPS location.

How To Successfully Use UPS MI and USPS

When using UPS MI, follow these tips to ensure USPS acceptance:

  • Double check you purchased UPS Mail Innovations service for the package
  • Verify the shipping label states "UPS Mail Innovations"
  • Look for a UPS MI tracking number starting with "92"
  • Bring to any USPS Post Office location for drop-off

As long as these criteria are met, USPS is contractually obligated to accept the package.

Tracking and Customer Service

Once USPS takes possession of your UPS MI package, you‘ll receive a separate USPS tracking number. This allows you to track the final delivery on USPS.com.

However, you can also continue tracking on UPS.com using the original UPS MI tracking number. Both numbers will display updates as the package transfers between the two delivery networks.

If any issue arises with your UPS MI package at USPS, you can contact UPS customer service for help. Since you paid UPS directly for the shipping, they bear responsibility for managing USPS complaints or claims.

Should You Use UPS Mail Innovations in 2024?

Based on my experience, UPS Mail Innovations makes sense for these use cases:

  • You have a 1-5 lb package going to a residence
  • You want to save up to 25% on shipping costs
  • You frequently drop off packages at USPS already

However, I don‘t recommend UPS MI for:

  • Heavier packages above 5 lbs
  • Delivery to a business/commercial address
  • If speed is critical (2-5 days is slower than pure UPS)

UPS MI can provide big discounts compared to standard UPS Ground for lighter residential packages. Just be sure it has the proper UPS MI tracking number and labels to enjoy USPS drop-off.

I hope this guide provides everything you need to know to successfully utilize UPS and USPS together when shipping packages this year! Let me know if you have any other shipping questions.
