# Why I Failed Adding Bank Card to UnionPay App?

> Common reasons for failing to add a bank card to the UnionPay app, including card limits and frequent removal activity.

There are two main reasons why card addition might fail:

1. **Card limit exceeded**: Each UnionPay user can only add up to 10 bank cards. If you've reached this threshold, remove any cards you don't regularly use and attempt the process again.

2. **Frequent removal activity**: The system may temporarily block additions if cards have been recently removed. Wait some time before trying again.

For additional assistance, contact UnionPay's customer service at **95516**.
