The following chart outlines the delivery standards for various mail classes and indicates how long you should wait before you contact customer assistance with a concern.

• US Mail Service shipping always starts with the seller to bring your package to the local post office or a mail box. Bigger companies such as Amazon or Ebay do this every day, why smaller companies or private sellers, might only do it once or twice a week.
• A postman then takes your package together with all the other shipments. It is then shipped to a mail sorting facility via trucks.
• In these facilities, machines automatically sort all packages regarding shape and site. They also sort them in a way, that the address can be read automatically by machines.
• After this basic process of sorting the packages, they are delivered to different machines, which sort them to the right destinations.
• National shipments are then delivered to the right location by trucks and then finally delivered to you via a local post man.
• International packages have a longer way to go as they have to pass through customs first and then have to be sent to the destination country by plane, where the customs of the destination country checks the packages again. That is the main reason why international packages take much longer than national packages.

US Mail Service tracking number is assigned at the time when the order is accepted. The tracking number is also known as Article Number, and it comes with almost all the mail classes, and if it doesn’t, then you can add it by asking the Postal Service.

If you don’t have any idea that what your tracking number looks like, then see the table above.

It is normal for packages shipped through the Postal System to have little or no tracking information available. US Mail Service does not provide tracking for most services but instead provides delivery confirmation.

With delivery confirmation your package is usually only scanned when it arrives at your local post office and again at delivery. There is no pickup scan or other information that confirms your package was mailed.

Until your package arrives and is scanned at your post office you will see a message like the one below:

The Postal Service was electronically notified by the shipper on April 18, 2020 to expect your package for mailing. This does not indicate receipt by the US Mail Service or the actual mailing date.

If a shipment is “in-transit” then that means that carrier has scanned the package upon pickup and it is now en route to the end customer.

If a shipment stays ‘in transit’ for a prolonged period of time, it is possible it may have been delayed. There are many things that can delay an order past its original expected delivery date - poor road conditions, weather, and deliverability of the location are a few examples.

This status indicates that the package has left the carrier’s facility and is on its way to the end customer’s destination address.

This status indicates the package has been delivered to the end customer. The package will have been dropped off and the tracking should note the delivery date/time.

If for any reason any package is unable to be delivered, one of the below statuses may be encountered:

• Delivery Failure -This status indicates that the package was unable to be delivered for some reason (i.e.street number not found; no secure location available; no access; etc). Typically an order that fails to deliver will be returned to sender (explained below).
• Return to Sender -This status indicates that US Mail Service attempted to deliver the package to the customer but was unable to complete delivery for some reason - generally a carrier tries multiple times to deliver a package before processing a return to sender.

This status is essentially the same as the domestic one, but it is important to note that packages sent back from foreign countries may incur duties and taxes for the return (vendors are responsible for any duties or taxes incurred for a return). Depending on the fees, it may be beneficial to have the package disposed of at the destination country and another one sent in its place - this is of course up to the vendor’s discretion.

Inbound out of customs means that your package has been released from US customs to the US Mail Service and it is being delivered to you. If the term is Outbound, that would mean that the package you sent has passed through customs and it’s on its way to another country.

What Do Customs Do?

What exactly happens to your package or mail while it is in customs, what happens behind those closed doors.

In the last year, around 650 million pieces of international mail went through the customs to enter the United States, coming from foreign countries. Almost all of this immense quantity of mail is accepted into the US through one of its five International Service Centers (ISC). The five ISCs are located in New York, Miami, Chicago, Los Angeles, and San Francisco.

International Service Centers (ISCs) distribute and dispatch international mail received from a designated service area to specific foreign countries or to gateway exchange offices. Each center has been recognized for global leadership in international mail processing with an International Post Corporation (IPC) Certificate of Excellence award. This award, based on a common global standard for excellence in mail processing, is a months-long process involving an operational survey, pre-certification, and the actual certification process.

The IPC is an association of 24 postal operators in Europe, North America, and the Asia-Pacific region. IPC provides its members with systems and programs that ensure efficient and competitive delivery of international mail.

Does The Customs Clearance Process Work?

International mail in most cases ends up arriving at airports aboard certain inbound commercial carrier flights. When this thing happens, on the ground we have something called ground handlers (here, it depends a lot on the time the mail arrives at and on some different other factors, but these ground handles are usually either employees of the airline that delivered the mail, or, in other cases, outside contractors that are employed by the airlines).

These people are tasked with unloading the receptacles that contain mails and packages from inside the airplanes. Then, these same people take the mail and they take it to these ISC center that I mentioned above. While all these operations may sound sort of trivial, they are actually very important and they have to be done under a high degree of security.

US Mail Service employees are there in order to verify and monitor what the status of these international mail receptacles is. And they have to do this by completing reports that have become known under the name of ramp reports. Based upon these documents, anybody can find out instantly information about the mail, such as when it was sent, when it was scanned and assigned to a certain flight in its country of origin. Alongside this, you can also find the country where it came from, the airline on which it came on and the exact content and number of receptacles that are supposed to be brought to the ISC.

Then the mail goes through a process of verification, X-ray machines and other things like that, in order to make sure that it does not post any dangers for the postal workers that are handling it and eventually for the people that receive it. This is done in secure buildings and with the outmost care. And, as I am sure everybody knows, nobody is allowed to actually open your mail, that is confidential and opening it and breaching that trust is actually a federal felony. So checking your mail does not mean checking the actual contents of that mail, but the technical aspects of the mailing process and the safety of the packages.

Then and only then does mail enter into the final phase, where it is approved for the final delivery and can reach its original destination. If irregularities are found in the ramp reports or on the envelopes, or if the postal employees discover that the mail is eligible to poses certain risks, this process can take longer.

There are some uncommon tracking statuses that may be seen when checking a package’s tracking. A few examples include the following:

Damaged in transit - This indicates that the package was damaged while being delivered. For this, a claim would be filed through the carrier to receive some type of compensation.

Uncontrollable customs delay - This occurs when a package routed internationally is held up at customs for some reason. Typically there is not much that can be done in this scenario, except for having the end customer pay any outstanding duties or taxes.

Missed “In Transit” pickup scans (applies to US Mail Service international) - Sometimes an internationally routed package sent via US Mail Service can stay stuck “in transit” for a long period of time and then all of a sudden update to “delivered.” It is important to note that since US Mail Service does not guarantee international tracking, packages sent out at this service level can lose tracking updates once it hits the destination country

Your tracking number can be found in the following places:

• Your Post Office™ shipping receipt
• Your sales receipt if you bought insurance at the Post Office™
• Your email confirmation if you shipped from website
• The shipping confirmation email you received from an online retailer
• The bottom peel-off portion of your US Mail Service Tracking® label

If you DO NOT HAVE the tracking number from the mailing label or receipt (recipient). If you were notified by a shipper that they have sent out a package and believe it has been delayed or possibly lost, contact the mailer/shipper of the item and request them to track the item and provide you with the tracking number.

US Mail Service tracking not updating for International or Priority Mail? US Mail Service tracking works absolutely fine most of the time, but there may be few circumstances where the tracking is not updating.

First make sure that you’re entering the correct tracking number. Following are the place where you can get the tracking number.

• Find tracking number on the Sales receipt, if you bought insurance at the Post Office
• Check the confirmation Email from US Mail Service or your online store
• See a bottom peel-off portion of US Mail Service Tracking label
• The back of the orange slip you received if you missed a US Mail Service delivery

What are the reasons behind tracking not updating?

US Mail Service tracking is an end to end mechanism. Every shipment has a barcode which is scanned as a package moves from place to the another. A barcode is scanned multiple time before reaching the destination. You see tracking updates whenever a barcode is scanned.

Here are few reasons of US Mail Service not updating:

• Package Not Scanned: Barcode scanning is the reason why you’re seeing tracking updates. There is a possibility that a barcode is not scanned due to any reason and that’s why your tracking is not updating. Tracking information won’t update until the scanning is done.
• Weather Conditions: Weather could be the reason why your tracking is not updating. Sometimes the packages get stuck in the middle due to bad weather conditions.
• Packages are not scanned at intermediary stops: As mentioned above that a package is scanned multiple time before reaching the destination. There might be chances that a package is not scanned at intermediary stops due to unavoidable reasons or circumstances.
• Broken or Unscannable Barcode: A barcode won’t be scanned properly if it is broken or unscannable.
• Delay on the part of the carrier: There might be a delay on the part of the carrier and that’s why your tracking is not updating.

I’ve received my packages, but still US Mail Service tracking is not updating

This is also a possibility, it happens mostly during the holiday period when there is a rush of mail packages. In such situations, US Mail Service may skip the scanning process in order to tackle the huge demand.

Hence, when the US Mail Service is already lagging behind, to move the packages quicker, they often skip the scanning which leads to the US Mail Service tracking not found.

For International Mail, only Canada has tracking for US Mail Service priority mail. For all other countries tracking will only go as far as it reaching the country you are mailing to. Then it goes into that countries postal service and tracking stops. You have to use US Mail Service Global Express (1–3 days) or US Mail Service Priority Mail Express (3–5 days) to get tracking all the way to delivery.

Sometimes US Mail Service packages are delayed or rerouted because of unusual circumstances. US Mail Service provides several tools and options to help determine where your parcels is in the mailstream and if it is delayed or not.

US Mail Service do not have the ability to find out when a mailperson will arrive at a specific location.

Don't worry yet. US Mail Service may experience temporary rush of deliveries, and some packages are taking longer to be processed than usual.

Recently, there has been a new event appearing on packages, "In Transit". This event appears on items that have not had an actual device scan them in 18 hours. This means that the item is possibly still in the plane, train or automobile (this reference may be lost on some), that it was put on for transport. It also can mean several other things.

• It can mean its been offloaded, but not processed yet. Volume is high, and we can only move so fast. Machines break down, so do people. If you haven't paid for Priority Mail Express, you have no guarantee of service. Sorry, but that's the truth. No facility wants to "sit" on parcels at all, but when the workload exceeds the facility's capacity, it happens. If that happens enough in a short period, it can cause some significant backups.
• All packages move in large metal containers. Each one has a barcode assigned to it. When a parcel is put into that container, it will be tied to that barcode. Any events scanned to that barcode then populate for the packages contained within. Sometimes these Barcodes get damaged in transit, so packages will go dark for a while, as unloading the cage and scanning each individual item is not efficient.
• This scan does not necessarily mean your package has been stolen, destroyed, run over, tossed in a ravine. It can simply mean it got stuck in a pileup at a facility.
• It can also mean it got stuck on a transport that broke down, or for some reason was legitimately delayed(foul weather for aircraft, severe weather for trucks). In my neck of the network, if we have a truck break down on the way from the plant in foul weather, it may delay the mail almost ten hours. Enough time to trigger an "in transit" event.

If waiting doesn't help,sStart an online inquiry through the US Mail Service website. It has a miraculous way of “shaking loose” stuck packages, or forcing a tracking update when one hasn’t posted. Often times you’ll get a response a few days later (after it shows delivery) saying it was delivered on X day. If it’s genuinely lost (it probably is not), you’ll at least know what’s happening.

Usually, United States Mail Service vehicle and delivery persons delivers all packages around 5:00 p.m. local time Monday through Saturday. US Mail Service Priority Mail Express packages and Amazon parcels are the only pieces of mail delivered on Sunday Whole day.

The US Mail Service traces its roots to 1775 during the Second Continental Congress, where Benjamin Franklin was appointed the first postmaster general.

FedEx and UPS compete directly with the Postal Service in the area of fast mail and parcel delivery. Because of the postal monopoly, these companies are not allowed to deliver non-urgent (regular) letters, as well as use private and commercial mailboxes to the United States. These services also deliver packages that are usually larger and heavier than the US Mail Service can accept, and, unlike regular mail, they put trace numbers on each package or package. DHL Express was the third major competitor until it stopped servicing domestically in February 2009.
