If your tracking number appears invalid or does not show any updates yet, please don’t worry. A single order may be shipped in multiple packages and handled by different carriers, such as UPS, FedEx, or USPS. Because of this, some tracking numbers may become active earlier than others.
Here are some common tracking number formats:
- UPS tracking numbers usually start with “1Z”
- FedEx tracking numbers are usually 12 or 15 digits
- USPS tracking numbers are often 20–22 digits
In some cases, a tracking number may not be searchable immediately after it is created. Carrier systems can take some time to activate and sync the tracking information.
If you still cannot find any tracking details after some time, please contact our support team at support@udpwr.com, and we will be happy to help check your shipment status.
