USPS tracking

USPS tracking

USPS is the official postal service in the USA. FedEx and UPS immediately compete with USPS Express Mail and package delivery couriers, doing nationwide deliveries of urgent letters and packages. Due to the USPS monopoly, other couriers in the USA are not allowed to deliver non-urgent letters and cannot ship to U.S. Mail boxes at residential and other business locations.

Ship24 offers USPS tracking by simply entering your USPS tracking number on the homepage. Get real-time events of your USPS packages and follow their journey to your doorstep with Ship24.

How can I track my USPS package?

Tracking USPS packages can be done by using your USPS tracking numbers, which are assigned when you register a package. You can use your tracking numbers on the USPS official tracking website or on a third-party tracking system, like Ship24.

While USPS tracking can only track USPS packages, the universal Ship24 tracking system makes package tracking a non-issue. Ship24 constantly connects and scans hundreds of couriers and even more online shops, making sure you keep the most up-to-date with any developments on your USPS package. it can perform global tracking effectively regardless of the courier.

Indeed, buyers no longer need to use USPS tracking services at all and are flocking to the one-stop-tracking-shop - Ship24.

How can I track my USPS international package?

USPS international package tracking can be done with a universal tracking solution. Ship24 does just that. You can enter your USPS international tracking number on the homepage and after a few seconds, Ship24 will give you all the tracking information needed for your package, whether it is domestic or international shipping. The great thing about tracking your USPS international package on Ship24 is that you can track up to 10 packages simultaneously.

Although the USPS does have shipment tracking services as part of its operations, packages carried by the USPS are not just handled by the company and are more and more often being delivered by other couriers, subcontracted by the company. Therefore, packages handled by the US Postal Service could be passed over through different couriers as they make their journey to their final destination.

For example, if you shipped your USPS package to another country and it arrives in France, the United Kingdom, or India, then La Poste, Royal Mail, or India Post will be the ones handling the packages and delivering them to you.

Any number of handlers deliver packages for the USPS, depending on where the package's destination is, as well as the size and weight of a package in certain circumstances. Consequently, the tracking options available from USPS are sometimes lacklustre for individuals and businesses wanting the best possible tracking options for their shipments via the company.

Ship24 auto-detects couriers handling any USPS packages just from the USPS international tracking number you provide. The truth is that packages - during their journey - go through complicated progress as they can be handled by many different couriers and potentially under evolving tracking numbers.

The Ship24 tracking system, which is universal, is made to handle these shipment changes to stay abreast of any changes that should happen with your USPS package. You don't have to select which courier is being used, even if you have specifically used USPS, as Ship24 interprets your tracking code and finds where your package is, and whoever it is with. Indeed, our core tracking data sources are constantly monitored to ensure you get the best possible tracking information.

Similarly, you can also get tracking USPS international tracking from their tracking website as well. While you can track up to 35 tracking numbers on the USPS website, separating each tracking number by putting may be a hassle and time-consuming.

Has the USPS changed international services on its packages?

The USPS has made some changes to the names of international service options recently which should be noted by customers looking to use USPS services.

USPS International Service Options

The following changes are listed below for consumer knowledge while making package delivery purchasing decisions with the USPS:

  • Airmail - also known as Letter Post - is now called First-Class Mail International. This type of mail covers small packages weighing up to four pounds, or 1.8 kilograms.
  • Air package Post has been replaced by Priority Mail International (PMI)
  • United States package Service - Supplied mailing boxes for Priority and Express mail are now able to be used for international use.

How do you get free USPS shipping?

If you are purchasing USPS shipping directly from the postal operator, you will need to pay for the service which you require. In this instance, there are no free shipping options available. However, if you are purchasing an item from a marketplace or online store that sends packages with USPS, your USPS package shipping cost may be covered by the business or seller.

If this is the case, you should be made aware that you are not responsible for paying for USPS shipping at the point of purchase. Many marketplaces and businesses offer free shipping on USPS packages to incentivize the purchase of their product.

Can you track free USPS package shipments?

Whether you purchase USPS package delivery services directly or if an item you order has free USPS shipping included in the purchase, you can always track your USPS order with Ship24. All USPS orders are registered, meaning that they will be given an official USPS tracking number and you can use this number to track a USPS package on the Ship24 website.

Many people choose Ship24 when tracking USPS packages because the postal operator often partners with multiple other private couriers and logistics operators, especially where international delivery is concerned.

To give you an example, if you order goods from Europe and are located in America, often the first part of the journey of your package will be handled by a European courier company first (for instance from the warehouse or shop it is being picked up from), before travelling overseas with a logistics company (whether by sea or air), before being received by USPS in the US and delivered by them.

The same applies if you are sending goods out of the US (or ordering from the US), but in this case, USPS would handle the first part of the journey.

With Ship24, you don't need to know who is handling your package when, or at what part of the journey it will change hands. Using just the USPS tracking number, Ship24 can recognize and follow the journey of your package regardless of how many times it changes hands.
