There are several places to check:

1. You can find out by looking at the seller’s information. Some will announce the default courier on the homepage, such as YTO Express by default. If Yunda Express is not available, please inform the customer service, etc.

2. There is an introduction below the product description, which says what courier is sent by default, and you can also see it.

3. Some merchants will even indicate the default courier in the first line of the product description when they hold an event, and if it is not available, they will send the post office or something like that.

4. Some merchants will indicate what courier is sent in the introduction of Wangwang.

5. After the seller ships the product, you can also see what courier the merchant has sent in the details of the product you have already purchased.

6. Directly ask the merchant’s customer service to ask what courier the seller generally sends, or you can specify what courier the seller wants to send, which is convenient for the buyer
