The most common situation is to take your ID card to the bank counter to check, so you can tell yourself that the information is more accurate. Or download a bank software that we need to query, then register, log in, bind the bank card and fill in personal information, so that we can query directly. Or we can call the bank's service hotline directly, follow the instructions on the phone, and then connect to the manual customer service, describe our own situation and make an inquiry. If it is a credit card, you can directly check the personal credit report. If it is a debit card, you need to bring your ID card to the bank business hall to explain the situation.

Knowing the bank card number is impossible to know the name of the head of the household.

1. According to the law, no organization or individual may inquire about personal deposit information without the authorization of judicial organs. Banks are obliged to keep deposits and business secrets for depositors;

2. Unless deceived by criminals, public security personnel go to the bank to inquire about relevant information after reporting the case;

3. Although the card number can be used to query the information of the account holder through the banking system, such as name, telephone number, ID number, address, etc., the bank will not provide these contents to others.

Banks will not tell the name of the other user only by a bank card number, except in special circumstances. (When a judicial crime is involved, the public security organ can bring relevant certificates and materials, ask the bank for help through the bank card number, and find the name and relevant information of the other party. If it is an inter-bank transfer, you need to know the other party's name and bank card number.

Precautions are as follows:

1. After receiving the new card, check the name, validity period and type of the bank card in time.

Sign on the back of the bank card as soon as possible. When writing, avoid using too neat signature, use the signature method that best represents you, and do not alter it.

3. Don't place the bank card at will, and don't lend the card or the front and back copies of the card to others for use.

To ensure safety, please don't put the bank card with the password of ID card or credit card. If you find that your bank card is lost or stolen, please call the customer service phone of the issuing bank immediately to report the loss.

5. When the bank card expires and a new card is issued, please destroy the magnetic stripe of the old card in time.

6. Protect bank card information.
