    About USPS

    The United States Postal Service (USPS), also referred to as US Mail, Post Office, and Postal Service, is an independent entity of the U.S. federal government's executive branch. Despite its independent operation, it holds the distinction of being one of the few agencies explicitly authorized by the Constitution. With approximately 34,000 retail locations, USPS is unmatched in its reach, delivering to every address nationwide. Its vast network manages almost half of the world's mail, making it the largest postal system by volume.

    Headquartered in Washington, DC, near the iconic National Mall, USPS has established relationships with global giants, including Amazon, its most significant client in 2019. Beyond its logistical achievements, USPS stands as a symbol of unity in the U.S., known for its dependable, affordable, and secure mail services, binding the nation together.

         - From the bottom portion of your USPS Tracking® label

    • How soon after shipping will I get the USPS tracking number?

    Moreover, if you book a shipment personally with USPS, either through the pick-up service or by visiting the company’s post office, the receipt will have your item’s tracking number.

    • What should I do if I don’t receive a USPS tracking number?

    Some items, like postcards, as well as First-Class Mail International letters and flats, don’t come with a tracking number. But you can purchase an extra service to qualify for package tracking. If your shipment should have a tracking number but you didn’t receive one, here’s what you can do:

    As a sender, you can check the receipt, email, shipment label, or another service used to buy online postage to see if a tracking number was provided.

    As a recipient, you can ask the sender for the tracking number or check on USPS Informed Delivery.

    • How to track a USPS package without a tracking number?

    You have very limited options available in case you lose your tracking number. The best way to track your shipment without a tracking number is by setting up a Delivery Account with USPS. This free service will let you preview your mail digitally, manage your shipment deliveries, and track them.

    All you need to do is:

    1. Set up an account with USPS and sign up for free in their Informed Delivery section.

    3. Select the option of ‘Enroll’, then scroll down to the Informed Delivery box.
    4. Answer the identity verification questions.

    In Transit / Arrived at USPS Facility / Departed USPS Facility

    The item is being processed and transported to your delivering Post Office™.

    Out for Delivery

    The package is currently with your delivery service and is expected to arrive today.

    Insufficient Address / No Such Number

    The package is on its way back to the sender due to an issue with the delivery address, which may be incomplete, incorrect, or missing some details, preventing successful delivery.

    No Access to Delivery Location

    Delivery was incomplete because the carrier could not access the location.

    Notice Left (No Authorized Recipient Available)

    The package needed a signature, but no one was present to provide it. The delivery person left a PS Form 3849 Redelivery Notice. A second delivery attempt won't be made automatically.

    Available for Pickup

    The package couldn't be delivered and is now ready for collection at your nearby Post Office™ during its operational hours. You or a person you authorize can pick it up. Redelivery for this item isn't an option.

    Shipping Label Created, USPS Awaiting Item / Pre-Shipment Info Sent to USPS Awaiting Item

    Notice Left (No Secure Location Available)

    Held at Post Office, At Customer Request

    Delivery Status not updated

    Shipment Received, Package Acceptance Pending

    A mail center has taken in a container or pallet with several packages, but the processing hasn't begun. When the container gets opened, every package inside will be scanned to show it's been accepted by the postal service.
