FAQ

1. What is a "valid proof of purchase"?

A valid proof of purchase is information that proves that you have completed your purchase from an official source, usually including:

  • The order number of the official platform Mai from the official store (such as Jingdong/Tmall/Douyin/Pinduoduo Mai from the official flagship store and Mai from the offline store);

  • Complete electronic invoice or transaction screenshot;

  • Payment records containing official store information, time, and amount;

It is recommended that you keep the above information properly so that you can provide it when applying for after-sales service.

2. What if there is no proof of purchase?

If you buy directly from Mai from official channels such as Jingdong/Tmall/Douyin/Pinduoduo Mai from official flagship stores and Mai from offline stores, we may have your purchase record and can find it for you. We may be able to find it with your name, address, etc.


If you buy from other third-party platforms, individual sellers and second-hand transactions, you can try to contact the seller to see if they can provide the original order information.


If the product is given away, we recommend that you ask the giver to provide you with an invoice. If the requested invoice is not appropriate and they can handle the limited warranty process for you, you can also ask them to handle it on your behalf.

  • After the normal connection can not be identified and other abnormalities;
