USPS Map Tracking

Anish

November 16, 2023

When FedEx (Federal Express) introduced its Customers, Operations, and Services Master Online System (COSMOS) in the late 1970s, it revolutionized the shipping industry.

This system allowed shippers and recipients to receive essential updates on their parcels’ whereabouts and what would form the backbone for modern package tracking services.

The U.S. Postal Service (USPS) takes FedEx’s fundamental concept and pushes it further with its USPS Map Tracking feature, allowing you to monitor your mailpieces in real time, from departure to arrival at their final destination.

This article will dive into USPS Map Tracking, exploring what it is, how it works, and why it’s a valuable tool for anyone who relies on the Postal Service for their mailing needs.

For more information on how you can stay informed about your packages, head to your local post office. Visit FindPostOffice.org to quickly find your area’s nearest and most convenient USPS facilities.

What Is USPS (United States Postal Service)?

Before we dive into USPS Map Tracking, let’s briefly discuss what USPS is. The United States Postal Service, also known as the U.S. Mail service, Post Office, or Postal Service, is an independent agency of the federal government that provides mail delivery services in the United States. 

USPS is renowned for its extensive network of over 31,000 post offices and its vital role in delivering mail and packages to millions of Americans. Regarding package delivery, the U.S. Postal Service handles roughly 44% of the world’s mail volume.

USPS accomplishes these feats through its various domestic and international shipping services, ranging from expedited delivery options, like Priority Mail and Priority Mail Express, to economical choices, such as First-Class Mail and Ground Advantage (Retail Ground).

Does USPS Have Live Map Tracking?

The U.S. Postal Service offers a feature known as USPS Map Tracking, which allows you to follow your USPS shipments in real time on a map. However, it provides this service through USPS Tracking Plus, a premium monitoring feature, meaning it isn’t available with the standard monitoring tool.

You must pay a small surcharge to enjoy the benefits of USPS Tracking Plus. Fortunately, some third-party websites and apps like My Package Tracking and GoComet offer USPS Map Tracking free of cost.

About USPS Tracking: Track Delivery of Your USPS Shipments

At its core, USPS Tracking reduces shipper and receiver anxiety by providing updates on the status and location of a package shipped through the Postal Service, including the date and time of delivery.

Fortunately, USPS includes the standard monitoring feature with almost all its mail and package delivery options at no additional cost. You can purchase this tool as an add-on for services without a monitoring feature, such as First-Class Mail and USPS Marketing Mail.

To improve your package monitoring capabilities, such as live map tracking, consider paying for USPS Tracking Plus or using a third party offering USPS Map Tracking. Doing so enables you to ride along your parcel up to the minute throughout its journey.

Why Is Package Tracking Useful?

Whether you’re utilizing the standard USPS Tracking service included with most Postal Service shipping options, the premium version, or the real-time monitoring ability of USPS Map Tracking, package tracking is a valuable tool for several reasons.

Here are some key benefits of monitoring your USPS mailpieces:

  • Peace of mind: Knowing the whereabouts of your package and having insight into its estimated delivery time and date can ease anxiety and uncertainty, especially if your mailpiece contains time-sensitive documents or valuable items.
  • Delivery planning: Many individuals can’t spend an entire day waiting for a parcel to arrive at their doorstep. With USPS Tracking, you can anticipate the delivery, ensuring you can receive the package.
  • Issue resolution: If any problems arise during shipping, such as issues with customs for international packages, tracking information helps you identify and address them promptly.
  • Customer satisfaction: Tracking isn’t limited to individuals. Businesses can also benefit by allowing customers to monitor their shipments’ progress, increasing customer satisfaction.

How Does Package Tracking Work?

Understanding how package tracking works can demystify the process and help you make the most of USPS Map Tracking. Fortunately, mail tracking is straightforward.

USPS assigns tracking numbers to parcels that go through its network. The agency updates these mailpieces’ information whenever they’re scanned manually by postal workers or via automated machines.

You can check these items’ status and location updates by entering their tracking numbers on the USPS website at USPS.com. Alternatively, you can visit a post office and ask a Postal Service representative. Quickly find USPS facilities in your area with FindPostOffice.org.

Can I Track Precisely Where My Package Is?

The USPS Tracking service offers end-to-end monitoring. In other words, it lets you see a package’s current status and additional tracking information, including the delivery location.

However, this benefit is only available for most domestic USPS mail classes. Although USPS includes tracking capabilities for international products, there may be gaps in the information you receive, as destination restrictions can apply.

Additionally, while USPS strives to provide updates whenever and as soon as possible, some package tracking information updates can take up to 48 hours. In other words, USPS Tracking is only near real time.

Monitoring Your Package in Less Than One Minute

Fortunately, USPS Map Tracking services allow you to monitor packages minute to minute. All you have to do is sign up for USPS Tracking Plus or visit a third-party website or app offering real-time map tracking, enter your parcel’s tracking number, and see its whereabouts on a map.

Can I View the Live Location of My USPS Parcel on a Map?

While USPS’ tracking information can take up to 48 hours to update, third parties offering USPS Map Tracking boast real-time parcel tracking, showing a parcel’s live location on a map.

Moreover, these websites and apps provide an up-to-the-minute visual representation of domestic packages’ and international shipments’ routes and locations.

Priority Mail Delivery Map

Aside from the USPS Tracking Plus service, the U.S. Postal Service also provides a map feature for Priority Mail items, aptly known as Priority Mail Delivery Map. This map gives you an estimated delivery date of a Priority Mail item based on your area’s ZIP code.

While not as immersive as USPS Map Tracking, which can provide a parcel’s location on a map, this tool can help you plan your shipments accordingly, especially when time-sensitive deliveries are involved.

How Do I Track an Address With USPS? Where Is My USPS Package?

The barrier for entry to use USPS’ tracking feature is low. You only need your USPS parcel’s unique identifier or tracking number and enter it into the USPS Tracking page. You can also use your USPS tracking number on third-party websites and apps.

Find Out the Tracking Number

Your USPS tracking number is the key to accessing tracking information for your package. It can be a unique alphanumeric or an all-number code that the U.S. Postal Service assigns to each shipment, essential for monitoring its status.

How Can I Access Tracking Information From USPS Tracking?

Accessing your mailpiece’s tracking information is straightforward. Visit the USPS Tracking page at USPS.com or use its mobile app to enter your tracking number.

Conversely, you can send a text message with your tracking number to 28777 (2USPS) or call the customer service hotline at 1-800-ASK-USPS (1-800-275-8777) to receive the most up-to-date information available on your USPS package.

What Does My Tracking Number Look Like?

The U.S. Postal Service uses various tracking number formats depending on the specific service used to ship a parcel. Here’s what your shipment number may look like:

How Do I Find My USPS Tracking Number?

If you’re the sender, you can easily find USPS tracking numbers in the following places:

  • Sales or mailing receipt: If you’ve sent a package through a post office, its tracking number will usually be available on the sales receipt. USPS tracking numbers will also be visible on the parcel’s shipping label.
  • Shipping email confirmation: If you purchase postage online through USPS’ Click-N-Ship service, which allows you to print your tracking labels, you’ll receive a confirmation email including your mail item’s tracking number.
  • USPS.com account: When you sign up for services like USPS Informed Delivery, packages headed to your delivery address will automatically be included in the tracking list. Checking your USPS.com account will allow you to see these mailpiece’s tracking numbers.

If, however, you’re the recipient of a parcel, such as if you purchased an item from an online retailer like Amazon, the sender will generally provide you with the tracking number.

If you can’t find your USPS tracking number, call the Postal Service’s customer service hotline at 1-800-ASK-USPS (1-800-275-8777). Alternatively, visit a local post office, which you can quickly find with FindPostOffice.org’s USPS facility finder tool.

Follow Your Package

Once you’ve entered your tracking number on the USPS Tracking tool or a third-party site’s monitoring feature, you can follow your package’s journey from its point of origin to its final destination. Doing so enables you to receive valuable insights into your parcel’s status.

How Can I Track My International USPS Package?

Tracking packages heading to or from an international address is similar to monitoring domestic mail. Once you have the tracking number, input it into a tracking tool and receive updates on your shipment’s progress to and from other countries.

However, as mentioned, you may not receive the same level of tracking with international packages, as monitoring regulations can vary significantly between countries.

Additionally, mail classes like First-Class Mail International don’t come with end-to-end USPS Tracking. While you can purchase add-on services to receive tracking information for parcels shipped through these options, they may not provide you with near real-time updates.

For these reasons, consider utilizing third-party websites and apps that offer live monitoring capabilities for domestic and international mailpieces through USPS Map Tracking.

USPS Tracking Plus

You can review your previous parcels’ tracking information by logging into your USPS.com account. However, mailpiece records without signature confirmation only last up to 120 days. On the other hand, tracking data on signature items remains for up to two years only.

For a small fee, you can extend the duration of your packages’ tracking information to up to 10 years with USPS Tracking Plus. With this premium monitoring feature, you can also request delivery statements, perfect for record-keeping purposes and resolving claims. 

Benefits of USPS Tracking Plus

Arguably, the most significant benefit of USPS Tracking Plus is the map-tracking feature. However, it offers more than just enhanced monitoring capabilities. It also provides other valuable benefits that can be especially advantageous, including the following:

  • Delivery evidence for dispute resolution: When disputes arise, such as claims based on damages or missing mail, having access to USPS Tracking Plus gives you tracking information you can use as delivery evidence.
  • Legal and court proceedings: In legal and court proceedings, USPS Tracking Plus can serve as critical evidence of mailing, delivery, or delivery attempts, as legal and financial sources may accept your tracking history as official data.

How Long Does It Take USPS to Deliver?

Understanding the delivery times for the various USPS package delivery services is essential, especially for planning your shipments effectively. Here are some critical points you must consider:

Is USPS Package Tracking in Real Time?

The U.S. Postal Service strives to provide the most current information for your packages. Unfortunately, these status and location updates may not always be real time because USPS can only revise the tracking information as scans become available.

What Time Will My USPS Package Arrive?

Although USPS Tracking can estimate your packages’ arrival time, the exact second, minute, and hour a USPS driver will bring your mailpiece to your doorstep isn’t guaranteed.

USPS generally attempts to complete all deliveries between 9 AM and 5 PM daily. However, factors like the mail volume, weather, and events in your local area can influence this shipping window.

Estimated Delivery Times for Domestic and International USPS Services

The delivery date varies depending on the specific USPS service. Here’s an overview of the estimated shipping times for domestic and international packages:

Domestic
Priority MailOne to three business days
Priority Mail ExpressOne to two business days
USPS Ground AdvantageTwo to five business days
First-Class MailOne to five business days
Media MailTwo to eight business days
International
Priority Mail International6 to 10 business days
Priority Mail Express InternationalThree to five business days
Global Express GuaranteedOne to three business days
First-Class Package InternationalVaries by destination

Not Every USPS Package Can Be Tracked!

While USPS offers robust package monitoring and estimates delivery times, it’s essential to note that not every USPS package is automatically trackable. Some may require you to purchase extra services to obtain tracking information.

Here are the package delivery services that include USPS Tracking:

USPS Shipment Status: What Do My Tracking Statuses Mean?

You’ll likely encounter various status messages when checking your incoming or outgoing mailpiece’s progress using the standard USPS Tracking, USPS Tracking Plus, or USPS Map Tracking. Understanding what these tracking statuses mean can help you interpret what’s happening.

Here’s a breakdown of some common tracking statuses:

What Does The Status Update Pre-shipment Mean?

The “Pre-shipment” status indicates that USPS has received the shipping information from the sender but has not yet received the physical package for processing.

Delivery Exception, Local Weather Delay Status Update Meaning

If you see a “Delivery Exception, Local Weather Delay” status, it means that weather conditions in the delivery area are preventing the timely delivery of your package. This status is typically temporary.

Visible Damage Status Update Meaning

A “Visible Damage” status suggests damage to the package, which was noticed and documented by USPS. In these situations, you must contact the sender or the recipient and inform them. Note that you can file a USPS claim if your mailpiece has insurance.

What Does the Status Update No Such Number Mean?

If your parcel’s tracking status reads “No Such Number,” it could indicate an issue with the delivery address. Contact USPS or visit a post office location to determine your next steps and how you can rectify the problem.

Arrival at Unit Status Update Meaning

An “Arrival at Unit” status means that your package has arrived at the local post office or delivery unit and is being prepared for delivery to your address. Expect your parcel to be out for delivery soon.

My Shipment Status Shows “Delivered,” but I Can’t Find My Package. Where Is It?

If your tracking status shows “Delivered,” but you cannot locate your package, there are a few steps you can take. First, check your mailbox, garage, or other people present at your address who may have received the package. 

Sometimes, USPS may tag your mailpiece as “Delivered” up to 24 hours before delivery. However, contact USPS for assistance if the expected delivery date passes and your mail is still missing.

Customs Clearance Status Update Meaning

A “Customs Clearance” status message indicates that your international package has cleared customs. Once USPS retrieves the mailpiece, it will return the package to the USPS mailing network until it arrives at the final destination.

Payment of Charges Status Update Meaning

If you see “Payment of Charges” in your tracking status, the recipient must pay additional fees for taxes or duties to receive the shipment. USPS may send the package to the delivery address or hold it at a local customs office for pick up.

In Transit to Next Facility Status Update Meaning

“In Transit to Next Facility” signifies that your package is en route to its next destination or sorting facility. This routine status update during shipping may appear repeatedly until your package shows “Out for Delivery.”

What Does “Alert” Mean on My Tracking Status?

If your tracking status includes the term “Alert,” it means there’s a specific situation or issue with your package that resulted in its late arrival, such as bad weather. USPS will generally include further information on the alert.

Forward Mail With USPS Tracking

USPS also offers a mail forwarding service, allowing you to redirect your mail and packages to a different address. USPS Tracking can be a valuable tool when using this service to monitor the delivery of your forwarded mail.

However, the mailpieces you can forward depend on the type of forwarding service you choose or the change of address (COA) form you submit. Here’s what the three COAs can mean:

  • Temporary Change of Address: This COA lets you reroute First-Class Mail and periodicals for a specified time frame. However, it doesn’t allow USPS Marketing Mail and package services forwarding.
  • Permanent Change of Address: A permanent COA also lets you forward mail items. However, it has a longer service period: 12 months for First-Class Mail and 60 days for periodicals.
  • Premium Forwarding Service: The USPS Premium Forwarding Service (PFS) gives residential and business customers more control over rerouting, such as forwarding mail from a PO box.

Unlike the previous two forwarding options, PFS allows you to reroute virtually all mail classes, including Priority Mail, Priority Mail Express, and USPS Ground Advantage.

USPS Customer Service: How Do I Contact USPS Tracking Customer Service?

If you encounter any issues or have questions about USPS tracking, contact USPS customer service through their hotline at 1-800-ASK-USPS (1-800-275-8777).

Contact a Postal Service representative at your local post office for more personable assistance. Visit FindPostOffice.org to narrow the list of 31,000 USPS facilities nationwide to those in your area.
