The mobile phone number verification code is required for loan refund.

Lending treasure is a lending platform. Users usually need to provide their own mobile phone number for verification when borrowing money or investing in Lending Bao. In terms of refund, Lending Bao usually confirms the user's identity in the form of SMS verification code to ensure the security of the transaction.

When you apply for a refund, Lending Bao will send a verification message to your mobile phone number. You need to enter the correct verification code after receiving the SMS to complete the refund process. This is to ensure that only users bound by mobile phones can apply for a refund, and to prevent others from fraudulently using other people's accounts for refund operations.

If you don't receive the verification code, you can try the following steps:

1. Make sure your mobile phone number is correct and available. If you change your mobile phone number or have other mobile phone numbers, you need to make sure to log in with the bound mobile phone number.

2. Check your SMS trash can. Sometimes text messages may be mistaken for spam messages and automatically filtered into the trash can.

3. Make sure your mobile phone network is normal. If your phone has no signal or is in airplane mode, you may not be able to receive SMS.

If the above steps can't solve your problem, I suggest you contact Lending Bao customer service directly for further help. They will provide corresponding solutions according to your specific situation.
