United States Postal Service and EMS Tracking


March 22, 2024

USPS (United States Postal Service) joined the EMS (Express Mail Service) Cooperative in 1999.

The Universal Postal Union (UPU), a specialized U.N. (United Nations) agency coordinating postal operations among member states, created EMS to facilitate international express mail services. 

Suppose you send a mail or package to a foreign country via a USPS Express Mail service. In that case, you might wonder how to track your international shipment. 

Can you track your USPS item through EMS? If yes, how? Also, what are the meanings of each EMS and USPS tracking message?

What Is the Express Mail Service?

In the U.S., the EMS service is Priority Mail Express International (PMEI), a mailing option USPS offers. 

USPS is the United State’s primary postal service provider, supporting businesses, customers, and communities globally.

PMEI delivers EMS seven days a week, serving 350 million customers across the U.S.

Customers can purchase EMS at 32,000 retail stores and post offices countrywide.

How Does EMS Work?

EMS is a global delivery service offering one of the most efficient delivery options for domestic and international shipments.

Its core product is a cutting-edge delivery system where customers can pay extra to ensure the quickest delivery possible.

What Are the Main Features of EMS Parcel Delivery?

EMS offers these primary features:

  • Package acceptance at any post office or pick up from a customer’s address
  • An end-to-end tracking service 
  • Priority processing from initial parcel receipt to final destination delivery
  • Required signature upon receipt of item
  • Delivery to the addressee’s location

Note: Tracking features are subject to whether the original courier handles your order. Package tracking may switch between couriers if the handler changes while the package is en route. 

How Long Does EMS Shipping Take?

Express Mail Service is a well-known international postal service that handles pick-up and distribution of express mail to an addressee’s doorstep. The typical delivery time of EMS items starts at four business days.

Does EMS Deliver Through USPS?

As mentioned, EMS and USPS Priority Mail Express International may mean the same thing.

The latter term is how users call the service in the U.S. In contrast, EMS is the title most widely used term abroad.

USPS offers PMEI (part of the EMS offering) and Global Express Guaranteed (not provided by EMS).

How Has EMS Been Developing as a Service?

In 2019, EMS Cooperative participants delivered EMS export growth of over 20% for the Doha business cycle and the first two years of the Istanbul business cycle. 

EMS export volume trended 30% higher in that cycle compared to the first two years of the previous one.

The EMS global network provides multiple access points and delivers to every citizen and business with more than 200 operators worldwide.

How Do I Ship With EMS?

Say you ship an item abroad via EMS. A local courier usually handles the package’s domestic journey.

For example, you can drop off your parcel at a nearby FedEx (Federal Express) store. 

Once you’ve handed over your shipment at the FedEx counter, FedEx will deliver it to a freight forwarding depot. Afterward, the package will be sorted and shipped to its destination country.

The destination area’s local postal service does the final delivery.

EMS Tracking

You can track your EMS item by providing your 13-digit tracking number (for example, EZ987454321XX) assigned to each EMS item. 

You can get this code from the sender if you do not yet know your EMS item number.

Note: The UPU and EMS do not offer tracking notifications via phone.

USPS’ fastest domestic shipping option is Priority Mail Express. This service generally delivers seven days a week, all year round. With a money-back guarantee, next-day delivery applies to most U.S. and P.O. box addresses.

USPS Tracking Statuses

Here are two USPS tracking notifications you might receive:

  • “Delivered”: The package arrived at its destination with a recorded time, date, and location.

Suppose your package indicates a “Delivered” status, but cannot locate it. In that case, your carrier may have left it in a secure location.

  • “Out for Delivery”: The parcel is ready at your local post office, and a carrier will deliver it the day you receive the notification

Not all packages arrive via the same carrier that handles your everyday mail and may come at a different schedule or later in the day.

Why Is USPS Tracking Not Updating?

Say the tracking details aren’t updating. Ensure the tracking code you provided is accurate.

You may not see your shipment’s tracking information due to an invalid tracking number on the USPS Tracking page.

Here are other possible causes for your tracking info stopped updating:

  • Delayed courier: The carrier may face delay-related concerns, resulting in scanning delays. 

This lag may result in your parcel’s tracking information staying the same.

  • The barcode is damaged or unreadable: A broken barcode can be inaccessible to the scanner.
