Mail Tracking


June 9, 2023

Did you know that ancient Rome had a working postal service throughout its empire? “Cursus publicus” was the name of this service, and it was solely used for imperial matters. 

A single rider was accountable for the entire travel of the letter given to him. Senders and receivers don’t get notifications then, nor any means of real-time tracking of packages sent through this parcel service. The mail’s delivery status is accounted for only when the rider reaches their destination. 

Much has changed from that system to what courier services offer today, especially with today’s internet services. A sender or receiver can now track packages in real time through the mail tracking service. 

Today, mail tracking services are provided by all of the major courier companies in the United States. However, some customers may still have questions about this service, like the following: can you track your letter? How does mail tracking work? 

You may also wonder where you can find your tracking number and if you can track your mail without a tracking number. How can you check your mail before it arrives? What do you do if your mail does not arrive at its designated delivery time?

After reading this article, you’ll get a good idea of how mail tracking works and how to track your mail. You’ll also know where to find your tracking number and how you can track your mail even without one.

This article will also share tips on how you can check your mail before it arrives and the next steps you can take if your mail hasn’t been delivered.

Mail tracking is an excellent feature that helps you track your parcel. A tracking system is usually available to all couriers, such as FedEx, UPS, DHL, and even eCommerce websites like Amazon or eBay.

Can You Track Your Letter Mail?

By using the internet, you can track your mail practically anywhere. The USPS (United States Postal Service), one of the biggest delivery service providers in the U.S., offers mail tracking services to its customers. 

Mail tracking allows mailers to monitor their packages from drop-off at the post office to the mail’s final destination. In the case of USPS tracking, you can track your mail using this service. 

Also, you can use tracking services for mail sent to particular mail addresses like DPO (Diplomatic Post Office), FPO (Fleet Post Office), and APO (Army Post Office).

How Do I Track My Postal Mail?

You can track your item regardless of whether you are the sender or recipient through the services made available by the courier company. In the case of USPS, you can track your mail through the following methods: 

  • Online: You can track your mail through the online USPS Tracking System on to follow the progress of your USPS package.
  • By text: You can also text your tracking number to 28777 (2USPS) and get notifications through SMS. However, standard messaging rates may apply.
  • By smartphone: You can download the USPS Mobile app for iPhone or Android phones and conveniently access mail tracking on your smartphone. 
  • By Phone: You can call 1-800-877-8339 and obtain tracking information about your mail or package. 

How Does Mail Tracking Work?

Mail tracking is a complex system that involves the entire structure of a courier service. People inside processing facilities work with delivery staff who deliver your packages from point A to point B. 

At the same time, people keeping the online tracking system working keep a vigilant eye on ensuring correct information is displayed on their servers.

This complex process starts with the courier correctly placing a shipping label on a package or mail. Once a package has this label, courier personnel can scan your shipment at different processing facilities throughout its delivery journey. Every time your package is scanned, your tracking information gets updated.

Once your package is received by the courier company, in this case, USPS, the tracking service starts. Remember that your mail or package’s tracking number is on the shipping label.

Where Can You Find Your Tracking Number?

Now that you’ve sent your package for delivery, you’ll need to track it as it goes through the delivery process. You can do this monitoring using the mail or package tracking service. 

To do this, you’ll need a tracking number. You can find this number from the following sources:

  • Self-service kiosk eReceipt
  • Sales receipt
  • Mailing receipt
  • Online label records from Click-N-Ship, eBay, or other shipping services
  • Below the barcode of your mailed item

Remember that some USPS Marketing Mail items, postcards, and First-Class Mail letters do not have tracking numbers.

How Can You Track Regular Mail Without a Tracking Number?

Before you get anxious about not receiving a tracking number for an item, you should know that some mail pieces don’t include this number. Items without a tracking number are the following:

  • Postcards
  • First-Class Mail letters or flats
  • Periodicals
  • Some USPS Marketing Mail parcels

What Can You Do if Your Mailpiece Hasn’t Been Delivered?

There are instances where your mail can’t be delivered due to many factors. Delays may happen, resulting in deliveries not arriving on time. 

If delivery delays are the case, follow the next instructions: 

  • Check the delivery standard of your item’s mail class. You can find the time frame for the delivery of your item’s mail class in the delivery standard. 
  • Compare your package’s progress with what’s on the delivery standard chart for your item’s mail class.
  • If the item’s status is “Alert,” expect delayed delivery because of factors like weather events and natural disasters. 

How Can You See Your Mail Before It Arrives?

USPS has an optional notification feature called Informed Delivery, which allows you to digitally preview letter-sized mail addressed to you before it is delivered to your house. 

You get a preview mode for your mail, which you can access through your computer, tablet, or any mobile device. Informed Delivery is available in most ZIP code locations across the country. 

There are a few requirements for you to qualify for the Informed Delivery feature, including the following:  

  • Your address should be located in a ZIP code that qualifies
  • Your mailbox or address should be uniquely coded

High-density areas like apartments and condos may not have unique addresses with unique coding. If this is the case, you won’t qualify for Informed Delivery. 

Informed Delivery provides customers with the following notification features:

  • Digitized images of the envelope addressed to you
  • An email notification with digital photos of the first 10 mail parcels addressed to you
  • An online dashboard where you can view all photos of packages being delivered to your address

The Postal Service can digitize the image of an envelope by running it through automated mail-sorting equipment. The agency is now using that information to provide digital notifications to people before the arrival of physical mail.

USPS also provides updates on incoming packages via separate email or text notifications. The dashboard displays a window of seven days’ worth of mail images and package information for up to 15 business days after each delivered package.

People can sign up to receive a text or email alert when their package has been delivered.

What Type of Mail Requires a Signature?

According to USPS, mail that requires the signature or payment of the recipient or an agent authorized by the recipient is called “accountable mail.” Here are some items considered accountable mail: 

Adult Signature RequiredAdult Signature Restricted DeliveryInsured Mail (insured for over $500)Collect on delivery

Postage due or return postage dueCertified MailForeign origin mail with extra servicesSignature Confirmation serviceRegistered Mail
Restricted Delivery optionDomestic Priority Mail Express service items (unless signature waived is not required)Return Receipt service

You should note that Restricted Delivery service is delivered only to the addressee or a person authorized by the recipient to receive the mail or package on their behalf.

International Shipping Tracking

Before, when couriers had yet to develop their online tracking systems, people had no means of getting updates when they sent mail or packages overseas. They simply hoped that their package would reach their loved ones in another country.

Good thing you can now track your mail through the International Shipping Tracking services provided by companies like USPS. USPS services that have international shipping tracking are the following:

USPS International Mail ClassInternational Tracking Capabilities
Global Express GuaranteedTracking to all destinations
Priority Mail Express InternationalUSPS Tracking for most destinations

How to Track an International Parcel

Once you enter a tracking number onto the USPS Tracking website, the page will display the parcel’s current status. Depending on the type of goods of the packages and their origin or destination, you have the option to take several actions if required.

You can access the tracking history of the item and learn about which services are associated with it. You can request emails or text messages about your delivery. You can also leave instructions for the delivery driver on where to leave your piece of mail if no one is home.

What’s the Difference Between Certified vs. Registered Mail?

The main difference between Certified Mail and Registered Mail is the extra protection the latter provides. Registered Mail has added security for letters or packages with high value. 

Certified Mail provides the sender with mailing receipts and electronic delivery verification. It’s one of the mail services used by millions of Americans who need proof of delivery when sending sensitive items like bank documents, tax returns, and time-sensitive papers.   

On the other hand, Registered Mail focuses on providing extra protection for items of high value.

Both services provided regular updates on their delivery status. USPS creates a custody chain that gives you your parcel’s delivery status throughout its journey.  

To sum it up, choose Certified Mail if you need proof or certification of delivery of essential documents. If you need a safe, protected delivery for items of significant value, then Registered Mail is the service for you.
