How Do I Enter My USPS Tracking Number Into an All-Encompassing Tracking System?

Some third-party sites and apps allow you to monitor mail and packages from multiple carriers simultaneously in one convenient location. To track a USPS shipment, enter its tracking number into the system.

USPS Tracking Plus

With USPS’ standard monitoring service, tracking information remains for up to two years. 

For a small fee, you can extend your access to your tracking history for up to 10 years with USPS Tracking Plus.

Benefits of USPS Tracking Plus

The U.S. Postal Service’s premium monitoring tool offers several benefits, including the following:

  • Live map tracking: Although you can determine your parcel’s location with the standard USPS Tracking service, USPS Tracking Plus lets you ride along your shipments in real time on a map.
  • Delivery evidence: When disputes from damaged or missing mail claims occur, having access to your tracking history is essential, as you can use it as delivery evidence.

USPS Tracking Plus can also be advantageous as legal and financial sources may accept tracking information as critical evidence of mailing.

How to Track Missing or Delayed Packages

Occasionally, packages go missing or experience delays. If you need clarification about your shipment’s status and location, your first step must be to check USPS Tracking.

Note that USPS may take up to 48 hours to update an item’s tracking information. So, patience is essential. If you’re the intended recipient of a parcel, you can also contact the original sender.

If all else fails, talk to a Postal Service representative by calling the USPS customer care center or visiting your local post office to initiate a search request. Quickly find your area’s most convenient USPS facility with

Track Your Package

Like many other carriers, the U.S. Postal Service lets you monitor your parcels and receive critical updates on their status and whereabouts. However, USPS also offers different avenues to track and manage your mailpieces.

Get Informed Delivery

In a nutshell, Informed Delivery is a free offering by USPS that provides you with a digital preview of your incoming mail and package deliveries. It offers convenience and insight into what you can expect in your mailbox.

How Does Informed Delivery Work?

Informed Delivery works by capturing images of the mail and packages processed through USPS sorting facilities. These images are then made available through an online dashboard, which you can access on your email, USPS website, or mobile app.

How Much Does Informed Delivery Cost?

Unlike USPS Tracking Plus, Informed Delivery is offered by USPS as a free service. In other words, you don’t need to pay for a sneak preview of the pieces of mail heading to your doorstep.

Who Is Eligible for Informed Delivery?

Although you can get Informed Delivery at no additional cost, it may not be as readily available as USPS Tracking Plus. 

USPS determines the eligibility for Informed Delivery based on your ZIP code. Fortunately, most residential, business, and P.O. box addresses are eligible for this service.

How Do I Sign Up for Informed Delivery?

Signing up for Informed Delivery is straightforward. Here’s a step-by-step guide:

  • Visit the USPS website and head to the Informed Delivery page. Then, click the “Sign up for Free” button.
  • Determine your eligibility for the service by providing your address details.
  • Verify your identity using a one-time numeric passcode, which will be sent to your provided contact number.

That’s it!

What if I Can’t Verify My Identity Online?

In cases where Informed Delivery online identity verification is challenging, USPS offers an alternative method for confirming your identity. This option involves visiting a USPS facility offering in-person identity-proofing services.

Fortunately, 18,000 locations across the country do. To find one in your area, visit and use the USPS facility finder tool.

Maximize Your Informed Delivery Experience

The USPS Informed Delivery service doesn’t only provide package previews. It also lets you set tracking notifications and shipment reminders and sign signature-required packages even if you cannot receive them in person.

Do More With Your Packages

Aside from the abovementioned additional benefits, Informed Delivery allows you to leave unique instructions for the delivery driver, reschedule a shipment, and manually add other USPS Tracking numbers to your monitoring list.

See Photos of Your Mail Before It Arrives, Free

One of the most remarkable features of Informed Delivery is the ability to view images of your incoming mailpieces before they arrive. 

These digital previews will usually be in grayscale. Still, participating mailers can replace these black-and-white images with colored ones.

USPS Electronic Signature Online

As cited, Informed Delivery allows you to register and sign for certain deliveries electronically. This feature can streamline the receipt of packages and reduce the need for physical signatures.

How to Track a USPS Order Using Informed Delivery

Informed Delivery offers previews of your mail and includes tracking information for your packages. It even automatically monitors parcels you paid for and shipped through the USPS Click-N-Ship service, which allows you to print labels online.

Head to your Informed Delivery dashboard and click the “Packages” tab to begin tracking. Doing so will display mailpieces on your tracking list. Click on the arrow icon next to the parcel you want to monitor.

USPS Package Intercept

If you need to stop a shipment on its tracks or redirect it to another delivery location, choose USPS Package Intercept. This service is available for most domestic mailpieces with a tracking or extra services barcode for a fee.

How It Works

USPS Package Intercept is a service that allows you to reroute packages to a post office location for holding or have them sent back to the original mailer. Note that this feature only applies to parcels that aren’t out for delivery or have been delivered.

Paying for Package Intercept

Unfortunately, USPS Package Intercept may involve additional fees. These additional costs include the $17.00 interception surcharge plus the postage cost of Priority Mail.

Determining Eligibility: What Is Eligible and What Is Not Eligible

Not all packages are eligible for interception. As mentioned, mailpieces available for interception are those with USPS Tracking or extra services barcodes and heading to a domestic address.

Mail items, such as USPS Marketing Mail and packages in transit to a Commercial Mailing Receiving Agency or P.O. box, are ineligible for USPS Package Intercept. Parcels exceeding 130” in total length and girth length also do not qualify.

USPS Delivery Instructions

Another way the U.S. Postal Service lets you manage your mail items is with its Delivery Instructions service. It’s a feature that allows you to specify how USPS will deliver incoming packages.

These instructions include leaving a package parcel at a different location, such as at your front deck, a local post office, or a neighbor’s house. 

How Can I Leave Delivery Instructions?

To leave Delivery Instructions, you must first check if your shipment is eligible for the service. You can accomplish this task by entering the parcel’s tracking number on the USPS Tracking page.

If your mailpiece qualifies for the service, you can leave unique directions for the Postal Service to follow, which will be available in the “Available Actions” section.

Does USPS’ Delivery Instructions Service Cost Extra?

Asking USPS to hold a mailpiece or redirect it to a different location within your delivery address’ ZIP code won’t incur additional costs. 

However, leaving instructions to send an item to another ZIP code or upgrading the package’s mail class will incur extra fees.

Will I Receive Email Notifications on My USPS Delivery Instructions Request?

When you leave delivery instructions, USPS will email notifications about your request’s progress and package delivery. 

Other Simple Ways to Manage Your Mail

Aside from the mail management options mentioned above, the U.S. Postal Service offers several other convenient methods to ensure your mail reaches its intended destination promptly and securely.

Forward Mail

If you need your mail forwarded to a different address, USPS offers standard and premium mail forwarding options that allow you to receive mail at your preferred location. These features are highly beneficial if you temporarily or permanently relocate to a different address.

Reserve A P.O. Box

USPS provides P.O. boxes where you can securely store mailpieces away from your home address and retrieve them more conveniently. One of the most significant advantages of reserving a P.O. box is the 24-hour access some post offices provide.

USPS Hold Mail

When you need to stop mail delivery temporarily, USPS offers a Hold Mail service. This option ensures that your mail is kept safe at your local post office until you’re ready to receive it.

Hold for Pickup

If you or your intended recipient prefers to pick up packages at a local post office, USPS provides a Hold for Pickup option. This free feature can be handy for valuable or sensitive deliveries.

Schedule Redelivery Service

Did you miss a package delivery? USPS offers a redelivery service that allows you to schedule a convenient time for your package to be delivered again. Note that this USPS option may be unavailable for some locations.

To determine if your area is eligible for the Postal Service’s redelivery service, visit your local post office. You can find post office locations with’s USPS facility locator.
