Recently, a mysterious legend about the last four digits of an ID card has been circulating online, and many people are curious about it. Originally, the last four digits of an ID card are not a simple combination of numbers, they contain special meanings and purposes. In this article, we will delve into the mystery of this ID card and explore its underlying meaning, so that everyone can have a deeper understanding of this ordinary but not simple number string.

First, let's understand the composition of ID number. The ID card number is usually composed of 18 digits. The first 17 digits represent the region, birthday, sequence number and other information, while the last one is the verification code. Among the 18 digits, we pay special attention to the last four digits, that is, the last four digits of the ID number.

These four digits are not actually randomly generated, but have certain patterns and meanings. They are generated based on an algorithm, and each number has its unique meaning. And this algorithm is the key to the mystery of identity cards that we will reveal next.

1. Digits 15 and 16: Code of the location

The 15th and 16th digits of the ID card number represent the code of the region where the ID card holder is located. China's Administrative division code is formulated by the National Bureau of Statistics, and each region has a unique code. By using these two numbers, we can quickly identify the province or municipality where the ID card holder belongs.

2. 17th place: Identification of gender

The 17th digit of the ID card number is called "gender identification digit". It is used to identify the gender of the ID card holder, with odd numbers representing males and even numbers representing females. This coding design allows us to intuitively know a person's gender without having to look at other information.

3. Bit 18: Check digit

The last digit of the ID card number is the Check digit, also known as the "verification code" or "tail number". It is not a randomly filled number, but is calculated using a specific algorithm based on the first 17 digits. The role of Check digit is to verify the accuracy of the first 17 digits and prevent the ID card number from being wrongly filled or forged.

We should be cautious and confidential about the last four digits of the ID card number. Although these four numbers cannot directly reveal too much sensitive information, they are closely related to an individual's identity. The disclosure of the last four digits of the ID card number may bring some risks of privacy disclosure. Therefore, in our daily life, we should properly keep our identity documents and avoid disclosing these information to others at will to ensure the safety of personal information.

In our daily life, we often need to provide the ID card number to handle various affairs, such as opening an account, handling a card, buying tickets, etc. However, when providing the ID card number, we should pay special attention to the following points:

1. Legality and compliance: When handling various businesses, ensure that the ID card number provided is legal and has not been forged or altered. Do not purchase or use others' identity documents to avoid violating the law.

2. Fraud prevention: ID card number disclosure may lead to fraud or other illegal acts. When receiving suspicious calls or text messages, do not easily disclose your ID card number and other personal information to avoid being cheated.

3. Secure storage: keep your ID card properly, and try to avoid carrying the ID card number with you or writing it on paper at will to prevent loss or disclosure.

In this article, we reveal the meaning and purpose of the last four digits of an ID card. These numbers are not simple combinations, but are calculated through rigorous algorithms, representing the region, gender, and verification information of the ID card holder. Understanding the secrets behind these things has given us a deeper understanding of this ordinary number string.

At the same time, we should also emphasize the importance of protecting personal identity information. In the era of information explosion, the risk of privacy leakage has also increased. Therefore, it is everyone's responsibility and obligation to protect personal sensitive information such as his/her ID card number.

Through the introduction of this article, we hope that readers can better understand and respect the meaning behind the ID card number, as well as the importance of using the ID card number correctly, and jointly maintain personal information security and social order. Let's expand our knowledge together and build a better future together!
