Why does SF keep reminding me that the verification code is wrong?

If you make the last four verification errors when using SF Express, you can try the following methods:

1. Check whether the input is correct: Please carefully check whether the last four digits are correct, and make sure that no wrong numbers or letters are entered.

2. Reacquire the verification code: If the last four digits of the error are entered for many times, the system will automatically lock the verification code, and you need to reacquire the verification code at this time.

3. Contact customer service: If you still can't solve the problem after trying the above methods, you can contact SF customer service and they will help you solve it.

4. Confirm the order information: Before entering the last four digits of the verification code, you need to confirm whether the order information is correct, including the recipient's name, address, telephone number and other information.

In short, if you make the last four verification errors when using SF, don't worry, you can try the above methods to solve the problem. If the problem still exists, you can contact customer service for help.
