How to check the sender by express delivery

To check the sender of the courier, you can try the following methods:

1. Check the label on the package. Many express parcels will have the sender's label or mailing information, including name, address and contact information.

2. Check the invoice, receipt or payment voucher of the package. These vouchers sometimes list the sender's information.

3, query email or SMS records. If you receive an email or text message from the sender, you can get the sender's name, email address or mobile phone number by looking at the records of the email or communication application.

4. Contact the courier company. If you receive a courier package, you can contact the corresponding courier company and provide the tracking number or other necessary information on the package, and ask them if they can provide the sender's information.
