I am new to Alipay, and I need to do the identification verification, but my international passport is expired. Can I still use it that way?

According to the Alipay verification process for foreigners, your passport is one of the required documents to complete the face verification ¹. However, it is unlikely that Alipay will accept an expired passport for verification purposes. To verify your identity on Alipay, you may need to present a valid government-issued photo ID, such as a current passport. If your passport has expired, you will need to renew it before you can use it for verification. https://www.howtotao.com/alipay-personal-account-for-foreign-users/
