What happened when I suddenly received a short message from China Construction Bank to verify it?

I suddenly received a short message from China Construction Bank to verify that someone used your card number to log on to the platform, modify important personal information or transfer money. To be on the safe side, don't give the verification code to anyone who asks you. (Note: No matter which organization receives the verification code, if it is not operated by itself, it is not necessary to pay attention to it. This may be the latest fraud. )

SMS verification code is easy to be stolen by fraudsters. Internet links and Trojan virus information may be tools for fraudsters to obtain personal information. Users can take some measures to prevent theft: on the one hand, they should be aware of protecting personal information, and don't click on unknown text messages, websites, etc. (Links that may be implanted with Trojan virus, and important information such as ID cards and bank cards are not filled in at will); On the other hand, different user names and passwords are used when registering different platforms, and it is best to carry out real-name authentication on the online payment platform.

The role of short message service:

The Bank launched SMS verification code service to enrich the security measures of online banking. This security authentication service enhances the security of online banking customers by coordinating and integrating the advantages of multi-channel interaction such as online banking and SMS. The transaction types involved in the bank SMS verification service include demand transfer and remittance, fixed-activity mutual transfer, enterprise transfer, inter-bank transfer, appointment transfer and batch transfer.

When there are changes or transactions in the funds in our bank card, they will send short messages to tell us the amount of bank card deduction.

How to change the SMS number?

Take China Construction Bank as an example:

1. To modify the SMS number, you need to bring your ID card and bank card, go to the nearby CCB outlet and tell the lobby manager that you want to modify the reserved mobile phone number.

2. Handle the bank's "inquiry and maintenance of personal customer contact information" business, and inquire whether there is a mobile phone number in the contact information and mobile phone contact information. If the mobile phone number doesn't exist, tell the salesperson to add a new one. If the mobile phone number already exists, please tell the salesperson that you want to change it, and then tell him the changed mobile phone number.
