We apologize in advance that Care Center agents and local Post Offices™ are not able to provide help or assistance recovering lost tracking numbers.
When an item does have a tracking number, it is generated and provided to the sender. If you are the recipient expecting an item, you can ask the sender for that number.
| Examples of USPS tracking number formats can be found on the USPS Tracking page, section “What does my Tracking number look like?” |
Please keep in mind that not everything has a tracking number. Postcards and First-Class Mail® letters without extra services fall into this category.
We invite all customers to sign up for Informed Delivery® notifications by USPS®. Most USPS® domestic packages tied to the address associated with your USPS.com® account will be automatically available on your Informed Delivery® emails and dashboard.
If you are concerned that an item is delayed or lost, whether or not it has a tracking number or you have its tracking number, see the following articles:

Can I use a redelivery number instead of a tracking number?
If you received a PS Form 3849, We ReDeliver for You! notice, you can use the barcode number on the notice to search on USPS.com® as you would use a tracking number to get information on the mailpiece(s). Note that entering the Redelivery barcode number will return all tracking numbers associated with that delivery attempt.
