What Is the Express Mail Service?

EMS (Express Mail Service) is a global brand of worldwide postal service products that provides one of the fastest deliveries. EMS delivers to more than 200 countries where people pay postage for premium end-to-end shipping for mail and packages. EMS has the following main features:

  1. Acceptance at any post office
  2. Pick up from a customer’s residence
  3. Priority handling from drop off to final delivery
  4. End-to-end tracking system
  5. Delivery to the recipient’s address
  6. Signature upon recipient’s acceptance

How Does EMS Work?

Because EMS is a global delivery service, it promises customers that they provide one of the fastest turnarounds for domestic and international deliveries. EMS makes it possible through an advanced delivery system where customers pay a fee or surcharge to ensure that their package is delivered quickly. 

Quick delivery is possible because the shipping process is handled by an association of couriers that work hand-in-hand to provide prompt delivery service. EMS offers deliveries to more than 200 countries, and courier services in those countries also work together to improve this service. 

EMS has a cooperative that manages this service. This cooperative is structured into three main groups, namely: 

  1. The General Assembly: consists of all members of the EMS Cooperative
  2. The Cooperative Board: consists of seven elected members
  3. The EMS Unit: functions as the secretariat of the cooperative

In the United States, EMS is the Priority Mail Express International service USPS provides. The U.S. Postal Service joined the EMS Cooperative in 1999 and has since been part of the global drive to deliver fast mail. The EMS service through USPS offers mail deliveries seven days a week in California, Texas, Florida, New York, Pennsylvania, and other states. 

What Is the Difference Between Priority and Express Mail?

USPS Priority Mail is a parcel service that provides customers with a way of sending mail or packages based on weight and dimension or using a flat rate box or envelope. It’s an affordable way of sending packages. The service is relatively fast. Deliveries must be completed within three days.

Many tracking statuses describe the situation of your package. Each status notification means a different thing, and it’s best to learn the meaning behind these statuses, as some terms might be vague and confusing. 

What “In Transit” Means in U.S. Mail Service

You get the “In Transit” notification when your parcel or package is being delivered from one facility to another. It’s the notification telling you that your parcel is moving and slowly progressing toward reaching its intended destination. 

What “Out for Delivery” Means in U.S. Mail Service

You get this notification when your parcel or package is already moving. The delivery status will get updated when your package reaches its destination. 

What “Delivered” Means in U.S. Mail Service

When your package arrives at the intended destination and the recipient receives the package, the delivery status will change to “Delivered.”  The mailing and shipping process is completed when the mail has reached its intended destination.

Other Tracking Statuses

Here are some tracking statuses you may see when sending mail via the USPS delivery service. 

  • Pre-shipment: your shipping labels are created but not yet scanned into the company’s network.
  • Delivery attempt: You get this notification when a USPS package handler delivers a package to a recipient’s address, but no one is there to accept.
  • Accepted: You get this notification when USPS has accepted your parcel at the sorting facility associated with the ZIP code you’re shipping from. You’ll also get this notification when the recipient receives the package. 
  • Available for pickup: You get this notification when your parcel arrives at your local post office or the specified USPS facility and is ready for pickup. 
  • Alert: You get this status when your USPS package experiences an uncommon issue or problem during delivery. 
  • Return to sender: When the package is returned to the sender due to many reasons.

How Long Does It Take for Tracking Information to Show Up?

USPS tracking usually gets updated within 24 to 48 hours. When your package is scanned, the tracking details will automatically get updated. You should ensure that it should be appropriately placed if you’re using a shipping label on your package. Make sure that the barcode isn’t damaged or covered to avoid delays. 

Package Shipped by U.S. Mail Service Shows No Tracking Information

It’s normal for packages shipped via USPS to have little or no tracking information. The U.S. mail service doesn’t always provide tracking for many of its services. Instead, USPS includes delivery confirmation. 

A delivery confirmation gets scanned when it reaches your local post office and is again scanned at delivery. You may not have other information that will confirm your package was mailed. So, don’t be perplexed if you encounter this kind of scenario. 

What Are the Reasons Behind Tracking Not Updating

Delays in the package’s delivery are common reasons for tracking information not updating. Suppose you still don’t receive updates after the delivery date. In that case, you must contact your retailer or shipper or open an inquiry with USPS. 

You’ve Received Packages, but Still, U.S. Mail Service Tracking Is Not Updating

Many reasons can cause your tracking information not to update. Among these reasons are inclement weather, packages not correctly scanned, packages not yet moving, and a package delivered, but the status still needs to be updated.
