US Postal Service (USPS) 客户常见问题解答

If you mailed a package without tracking, it may have been sent using a service that does not include tracking by default, such as First-Class Mail for certain items. Unfortunately, without a tracking number, we cannot provide information about the package’s status. In the future, consider selecting a shipping option that includes tracking for better visibility on your package's journey.

To find out about your missing package, you can use the tracking number provided when the package was shipped. Visit the USPS website and use the "Track" feature. You can also check any delivery notifications or messages sent about your package. If you have not received updates, it may be helpful to speak with a USPS representative for assistance.

There is a link to the most up-to-date contact information right here on this page that you are viewing. You can use that to find the appropriate way to reach a customer service agent.

No, the delivery date is not encoded on the envelope. The USPS does not print the delivery date on the envelope itself. Instead, tracking information is available for packages and can be accessed online or through tracking services provided by USPS.

Delays in package acceptance can be due to various factors, including high shipping volumes, staffing issues, or potential customs holds for international shipments. In some instances, packages may be pending acceptance if they are awaiting scanning or processing at a facility. We recommend checking the tracking status regularly for updates.
