If you misplaced or forgot your tracking number, don't worry. Here are some steps you can take to retrieve it:
1. Check your mailing receipt.
2. Look up your online label record through services like Click-N-Ship or eBay.
3. Refer to your sales receipt.
4. Refer to "USPS Tracking - The Basics" to know what a USPS Tracking label looks like and check below the barcode on your mailed item.
5. Ask the recipient if they are a current Informed Delivery subscriber; they should be able to see the tracking number on their dashboard.
