The ID number is an important personal identity document and should not be easily disclosed to others. We need to use ID cards when staying in hotels, taking trains or high-speed trains, or handling various businesses. Although many people know that ID cards are private, it is best not to lend them to others, and at the same time, bank cards can only be used by themselves.
However, many people don't understand the 18-digit number on their ID card, so why can't this 18-digit number be shared with others?
The 18-digit number on the ID card hides a lot of personal information. The first six represent provinces, regions and cities; The seventh to fourteenth delegates can know the date of birth of the individual; The next two digits are the police station code; The penultimate digit is particularly important to determine the gender of the ID card holder, with odd numbers representing males and even numbers representing females; The last digit is the check digit, which can confirm the validity of the ID number.
Leaking an ID number can be harmful in a number of ways:
First, in some Internet cafes where the management is not strict, friends can register for use if they do not have an ID card and enter their ID number.
Second, if others want to know your credit status or whether you are a dishonest executor, they can simply enter your ID number and name, and you can check it directly through your mobile phone.
Third, if your ID information is leaked, scammers may use it to apply for a loan or credit card and spend all the money in it. Doing so will have a direct impact on your personal credit.
When using various mobile apps, you will need to enter your ID number for verification. But don't worry, because many applications are now very demanding and require facial recognition in addition to entering an ID number.
In daily life, we must properly keep the copy of our ID card, our ID card, face recognition and various verification codes in our mobile phones, and never leak them. Once the ID number is leaked, or the mobile phone or bank card is lost, some people will directly set the same bank card password as the ID number, which will lead to the loss of funds. Therefore, we must take good care of our ID card and ID number.
