How long is a USPS tracking number?
A typical USPS tracking number will be a combination of 22 digits or characters consisting of numerical digits and alphabetic letters. Depending on the shipping service you select, the USPS tracking number can be either 11 or 13 digits long.
Where to find my USPS tracking number?
You can locate your USPS tracking number at the following places.
- On the shipping receipt provided by your Post Office™
- On the sales receipt, if you purchased insurance at the Post Office™
- From the confirmation email, if you have used USPS.com for your shipping
- On the confirmation email sent to you by your online retailer
- From the bottom portion of your USPS Tracking® label
How soon after shipping will I get the USPS tracking number?
Your USPS tracking number will be provided as soon as your sender books a shipment with USPS to be delivered.
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:
Set up an account with USPS and sign up for free in their Informed Delivery section.
Enter your address here to determine if it is eligible. If eligible, log in to your usps.com account and select ‘Informed Delivery’.
Select the option of ‘Enroll’, then scroll down to the Informed Delivery box.
Answer the identity verification questions.
Following these steps will allow you to track your packages through USPS’s online dashboard.
Before you track your USPS package, ensure you understand the various USPS tracking statuses.

Delivered |
The package was delivered on a recorded time, delivery date, and location and should be in your mailbox. |
A USPS Delivery Exception occurs when something unexpected happens and a package can’t be delivered on time. This could be due to many reasons such as incorrect address, recipient not being available, weather conditions, or other unforeseen circumstances that disrupt the normal delivery process. When a delivery exception occurs, USPS will update the tracking status to reflect the reason for the delay.
Mail is late when it doesn’t arrive within the expected delivery time frame set by USPS based on the mail class and destination. USPS has specific delivery standards for each mail service, along with guidelines on when to contact customer support if these standards are not met.
