Xiaoli is 16 years old this year, and she is old enough to apply for an ID card, which makes her very excited, and she asks her family to accompany her to apply for an ID card.
Soon after, Xiaoli got the ID card she was longing for, and she was very happy at that moment, and having an ID card meant that she was an adult.
Xiaoli hadn't seen her mother's ID card yet, so she asked her mother to show her ID card.
When she saw the last digit of her mother's ID number "X", she asked her mother curiously, why the last digit of her ID card is a number, while her mother's is a letter?
Xiaoli's mother said what this letter meant, and then Xiaoli asked how to pronounce the "X", which made Xiaoli's mother stumped.
Some people think that "X" reads a fork, some people think that "X" reads Aix, these two readings have also caused a lot of controversy, and its correct pronunciation is what Xiaoli's mother doesn't know.
Today, we will briefly talk about the correct reading of the tail number "X" of the ID card to solve this puzzle for you.
1. The importance of ID cards
In modern social life, the ID card is far more than just a proof of identity, it plays an increasingly important role, with a variety of derivative effects.
The use of the ID card is very wide, and it is one of the important documents that individuals must provide to handle various businesses and affairs.
Whether it is opening a bank account, applying for a mobile phone card, signing a contract, buying a property, registering a vehicle, registering a marriage, etc., residents are required to submit their ID cards for relevant identity information verification.
With the development of the times, many online services also require users who handle business to provide ID card information to the platform for real-name authentication to ensure the security and compliance of the service.
Of course, you also need to use a national ID card to travel.
For example, when purchasing various transportation tickets such as train tickets, plane tickets, bus tickets, etc., we are required to provide personal ID card information, so that we can purchase and collect tickets normally.
When checking in to hotels, entering scenic spots and other places, it is also necessary to show ID cards for identity verification, which is also to ensure the safety of residents.
The ID card is also one of the important documents for all citizens of the mainland to enjoy various social welfare rights and interests normally.
To put it simply, when we apply for social security, medical security, housing provident fund and other benefits, we need to provide ID cards for relevant identity verification and application.
Of course, when we go through the procedures of retirement, pension, reimbursement of medical expenses, etc., we also need to show our personal ID cards for relevant verification.
Nowadays, the more important the ID card, the greater the risk.
If the ID card is lost or stolen, the consequences are very serious, and our personal information is very likely to be leaked and used by criminals to participate in some illegal activities.
Therefore, it is crucial to take care of your identity documents.
We should avoid lending ID cards to others at will, and do not leak ID card information to strangers or transmit ID card information in an unsecured network environment.
If the personal ID card is lost or stolen, it must be reported to the relevant authorities in time and a new ID card must be issued.
In the process of reissuance, we need to provide some relevant supporting materials in accordance with the requirements of national regulations, and actively cooperate with the required investigation.
ID cards play a pivotal role in today's social life, and we should fully understand its importance and take good care of our personal identity documents.
We should also take the initiative to strengthen our awareness of the protection of ID card security to ensure that the security and interests of personal information are not harmed in any way.
In addition, there are many foreign friends who want to apply to become mainland citizens.
Because China is currently one of the largest economic countries in the world, with a vast market and a rich resource system, it is also a politically stable and socially harmonious country, and the public security situation is very good.
Some foreigners think that life in China is safer and more stable, but it is not so easy to join the mainland and become a mainland citizen.
2. The evolution and structural composition of ID cards
An ID card is a document used to prove the identity of the holder, which has the legal effect of proving citizenship and is issued to citizens by the governments of various countries or regions.
In the Sui and Tang dynasties, a kind of "fish charm" issued by the imperial court, this "fish charm" has the same meaning as an ID card.
"Fish charm" is mainly divided into two materials, namely wood and metal, the wood material is used by ordinary people, and the metal material is used by dignitaries, symbolizing the nobility of status.
In the Song Dynasty, it was transformed into a "waist card", and then in the Ming Dynasty, it was changed to a "tooth card".
In 1929, Ningxia established a resident registration system for the first time.
The main thing is to write the basic information of the person on a white cloth, which mainly records the person's physical characteristics, age, occupation and so on.
Then in the national period, it evolved into the national identity card of the Republic of China, which was made of paper, which covered the basic elements of ID card information.
In 1984, the first generation of ID cards was introduced.
The material of the first generation of national ID cards is different from that of our current ID cards, which were made of polyester film and a single-page format consisting of 15-digit codes.
In 1999, the mainland established and implemented a citizenship number system, and the identity code belongs exclusively to the individual, which cannot be changed.
In 2004, the second-generation resident ID card began to be renewed, using more advanced IC card technology, with two functions of sight reading and machine reading, and increasing fingerprint information.
The format of the ID number is composed of 18 digits, the first six digits represent the address code, and every two sets of numbers are a group, which in turn represents the code of the province, city, district and county.
Specifically, the first and second digits represent a code for our province, and the third and fourth digits are a code for the city where the resident is located.
The fifth and sixth digits are a code for the district and county.
The seventh digit to the fourteenth digit represents the date of birth code, which indicates the date of birth of the person subject to the national identity card.
This part of the number is a combination of the year, month, and day of the individual, with no separator in between.
The fifteenth to seventeenth digits are a sequential number, where the seventeenth digit indicates gender, odd numbers indicate males, and even numbers indicate females.
The fifteenth and sixteenth digits are a code of the local police station where the individual is located.
The eighteenth digit is a check code, and the function of this verification code is mainly to check the validity of the ID card.
3. The correct pronunciation of the "X" at the end of the ID card
In the 18-digit ID number structure of the mainland, the tail number "X" does stand out from the rest, and it represents a special verification function.
The appearance of this "X" is not arbitrary, but calculated according to certain rules.
Regarding the calculation method of the check code, it is obtained by a certain algorithm on the first 17 digits.
Specifically, each digit of the first 17 digits is multiplied by their corresponding weight, and then the product is added to get a sum.
This sum is divided by 11 to get a remainder. Finally, according to this remainder, the value of the checksum is determined by certain rules.
When the calculated remainder is 10, a problem is encountered.
Because the ID number must be 18 digits, if you directly use the number 10 as the check digit, it will cause the ID number to become 19 digits.
In order to solve this problem, the "X" in Roman numerals is used instead of the number 10 as the check digit.
This reading is both in line with the actual meaning of the "X" in the ID number and also avoids confusion with the other letters "cross" or "ex".
Therefore, when reading or mentioning the "X" on the ID card, we should read it exactly as "ten".
The main purpose behind this design is to ensure the accuracy and uniqueness of the ID number. Through the setting of the check code, the ID number can be verified to ensure that it meets certain rules and standards.
At the same time, due to the low occurrence rate of "X" as a check code (only 0.02%), it also increases the complexity and anti-counterfeiting performance of ID numbers.
As a special character in the ID card number, "X" represents a sophisticated verification mechanism, which reflects the rigor and scientificity of the mainland resident ID card number system.
The existence of this verification mechanism enables our ID number to be effectively verified in various occasions.
Whether it is handling banking business, purchasing tickets, applying for various certificates, etc., it is necessary to confirm the accuracy and authenticity of personal information through the verification of the ID number.
This not only prevents the falsification and fraudulent use of identity information, but also protects our personal information from being illegally obtained and used.
epilogue
The last "X" of the ID number actually represents the Roman numeral "10", so when reporting your ID number, you should pronounce it as "ten" instead of "cross" or "ex".
As Chinese citizens, understanding the special meaning of the numbers on the ID card not only helps us remember the ID number more effectively, but also makes us better understand the importance of the ID card and the scientific design behind it.
Therefore, we should read our ID number in a standardized way to ensure the accuracy and security of the information.
ID number is one of the most important pieces of identity information for everyone, and we must keep it properly in our daily life.
To avoid personal identity information being stolen by criminals, if the ID card is lost, it must be reported and reissued in time.
When we need to provide an ID number, we also need to carefully verify the identity information of the other party, so as to ensure that our information is not illegally obtained and used.
