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.
Please keep in mind that not everything has a tracking number. Postcards and First-Class Mail® letters without extra services fall into this category. If you’re unsure what a tracking number looks like, examples can be found in the USPS Tracking page, section “What does my Tracking number look like?”
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.
