The customer inputs the received verification code through online banking transaction of Postal Savings Office. Why does he prompt that the verification code is invalid?

1. Please ask the customer to verify whether they have received the SMS and enter it within 2 minutes at most after clicking the button to get the SMS verification code. If the time is too long, the password will exceed the service life;

2. SMS password will be invalid after one attempt. When the customer has not received the SMS password for a long time, the customer can click "click to resend" or "click to ask customer service to inform the mobile phone dynamic password" to obtain the SMS verification code again, and the initial SMS password will also be invalid; After that, you will often receive multiple mobile phone messages. The first received mobile phone message may be the SMS verification code that has not been sent before, and the verification code has expired. Please use the last received verification code to conduct the transaction.

3. The daily error limit of SMS verification code is 6 times. After reaching this limit, the SMS verification code will be locked, and the error message is "The number of dynamic password input errors on the same day exceeds the limit, please try again the next day". Lock on the same day, automatically unlock the next day, and lock permanently after 60 consecutive mistakes.

4. If the SMS verification code is permanently locked, please call 95580 Postal Savings Bank for consultation.
