This is caused by AliExpress's own risk controls on individual transactions; we understand and support AliExpress's policy here. If you run into this issue, we recommend trying again after some time.
Suggested steps:
1. Submit your billing statement and appeal to AliExpress — once approved, the card should work again.
2. Try using the card on a different platform to see if it works there.
3. If your appeal is denied but the card works on other platforms, this is AliExpress-specific risk control — you'll need to contact AliExpress customer support directly.
