Take the barcode 69369838000 13 as an example.
The bar code is divided into four parts from left to right:
1-3 digits: * * 3 digits, corresponding to bar code 693, which is one of the national codes of China. (690-695 are all codes of China, which are allocated internationally).
4-8 digits: **5 digits, corresponding to the barcode of 69838, representing the manufacturer's code, which is applied by the manufacturer and allocated by the state.
9- 12 digits: * * 4 digits, corresponding to barcode 000 1, representing the commodity code in the factory, which is determined by the manufacturer.
13: * * *1,corresponding to 3 of the barcode, is a check code, which is calculated by the previous 12 bits according to a certain algorithm.
Formula 13 bit algorithm:
1: take out the sum of odd digits of this number, c1= 6+3+9+3+0+0 = 21;
2: Take out the sum of even numbers of this number, C2 = 9+6+8+8+0+1= 32;
3: The odd sum is added to "three times the even sum".
4. Unit number of results:117 (117%10 = 7);
5: subtract this single digit from 10:10-7 = 3;
6: Take the single digit of the obtained number (excluding the remainder of 10) 3%10 = 3;
Barcode or barcode is a graphic identifier that arranges several black bars and blanks with different widths according to certain coding rules to represent a group of information. Common bar codes are parallel lines composed of black bars (referred to as bars) and white bars (referred to as spaces) with great differences in reflectivity. Barcode can indicate the country of production, manufacturer, commodity name, production date, book classification number, starting and ending place, category and mailing date, so it has been widely used in many fields such as commodity circulation, book management, postal management, banking system and so on.
Question 2: What do the numbers in the bar code mean? For example, 692 13 17906370. Thank you! 692 indicates that this bar code is used in China and 690-699 in China. The eight digits 692 13 179 represent a manufacturing enterprise. Specifically, which enterprise can be inquired through the website of China Article Coding Center. 0637 represents the products produced by this enterprise. 0 is a check code, which is calculated by a certain calculation method from the first 12 bits, and is used to check whether the scanning result is correct.
Question 3: What does the barcode stand for? The meaning of 13 in the bar code diagram means that the first three digits indicate the origin (country) of the goods. The last four digits indicate the manufacturer's commodity name, which is uniformly assigned to the applied commodity name by the coding organization of the country (or region). The next five numbers are the number of each product. Manufacturers classify products first, and then code them one by one. Manufacturers can code more than 654.38 million items. The last bit is the check code, which is convenient for the scanner to check the whole code and avoid misreading. If you want to distinguish authenticity by barcode, you must first know the barcode data of the manufacturer, and then compare them. Generally, there are methods to check the authenticity of regular products, such as SMS, telephone or Internet. These methods are implemented through the manufacturer's database. After you send a query request, the system will enter the database and compare the barcode data you sent with the data in the database. If it matches, it's true. If it doesn't match, it's fake. Others forged it. If you don't know anything, you can't tell the truth from the bar code. You can only see a string of numbers or English letters, or even nothing (the data under the bar code can be hidden), only a black and white bar code can be seen. Such a barcode can only be recognized by a barcode scanner. At present, ENA barcode, UPC barcode, 25 barcode, cross barcode, Kudba barcode, Sanjiu barcode and 128 barcode are commonly used in the world, among which EAN barcode is the most commonly used commodity. EAN commodity bar code, also known as general commodity bar code, is formulated by ean international and is widely used in the world. It is the most widely used commodity bar code in the world. At present, this commodity bar code is being used in China. EAN commodity bar codes are divided into EAN- 13 (standard version) and EAN-8 (abbreviated version). EAN- 13 general commodity bar code generally consists of prefix, manufacturer code, commodity code and check code. The prefix code in commodity bar code is used to identify the country or region, and the code is given in ean international. For example, 00-09 stands for the United States and Canada. 45-49 stands for Japan. 690-692 stands for Chinese mainland, 47 1 stands for Taiwan Province Province and 489 stands for Hong Kong Special Administrative Region. The empowerment of manufacturers' codes is organized by article codes in various countries or regions, while in China, the National Article Coding Center gives manufacturers' codes. Commodity codes are codes used to identify commodities, and the right to assign codes is exercised by the product manufacturers themselves. Manufacturers decide which * * * numbers to use on their products according to the specified conditions. At last, the 1 parity code is used to check the correctness of the L- 12 digital code from the left in the barcode. The coding of commodity bar codes follows the principle of uniqueness, so as to ensure that commodity bar codes will not be repeated in the global scope, that is, a commodity item can only have one code, or a code can only identify one commodity item. Commodities with different specifications, different packages, different varieties, different prices and different colors can only use different commodity codes. The standard size of commodity bar code is 37.29mm x 26.26mm, and the magnification is 0.8-2.0. When the printing area allows, the barcode with magnification of 1.0 should be selected to meet the reading requirements. The smaller the magnification, the higher the printing accuracy. When the printing accuracy can not meet the requirements, it is easy to read the bar code. Because the identification of bar code is realized by the color contrast between bar code and blank bar code, generally speaking, as long as the color can meet the requirements of contrast (PCS value), light color can be used as blank color, such as white, orange and yellow, and dark color as bar, such as black, dark green and dark brown. The best color scheme is black stripes and white spaces. According to the practical experience of bar code detection, red, gold and light yellow should not be used as bar code colors, and transparent and gold should not be used as blank colors. EAN-8 commodity bar code refers to the 8-digit commodity bar code used for identification, which consists of 7-digit commodity item code and 1 digit check code. The birth of commodity bar code greatly facilitates the circulation of commodities, and modern society cannot do without commodity bar code. According to statistics, at present, there are 500,000 kinds of products in China that use the international commodity bar code. After China's entry into the WTO, enterprises will surely win more space for activities on the international stage. It should be in line with international practice and meet the needs of international economy and trade. & gt
Question 4: What do the numbers on the food bar code mean? Take the barcode 69369838000 13 as an example.
The bar code is divided into four parts from left to right:
1-3 digits: * * 3 digits, corresponding to bar code 693, which is one of the national codes of China. (690-695 are all codes of China, which are allocated internationally);
4-8 digits: * * * 5 digits, corresponding to 69838 of bar code, representing the manufacturer code, which is applied by the manufacturer and allocated by the state;
9- 12 digits: * * 4 digits, corresponding to barcode 000 1, representing the commodity code in the factory, which is determined by the manufacturer;
13: * * *1,corresponding to 3 of the barcode, is a check code, which is calculated by the previous 12 bits according to a certain algorithm.
Question 5: What does the barcode number of a book mean? A * * * after ISBN is 13 digit, which is divided into five groups. A-B-C-D-E
A is 978 or 979, which is a special prefix code assigned to books by ean international.
B is the team number, and China is 7.
C is the publishing house code, with 2-6 digits.
D is the serial number of the book, which is arranged by the publishing house in the order of publication.
E is the check code, 1 bit. Used to check whether the data is correct when the machine reads the bar code.
Question 6: What does the first number 4 in the bar code mean? This is a lot, and it depends on the first two or three digits to judge.
400 ~ 440 Germany 450 ~ 459 490 ~ 499 Japan 460 ~ 469 Russia 470 Kyrgyzstan
47 1 China Taiwan Province Province 474 Estonia 475 Latvia 476 Azerbaijan 477 Lithuania 478 Uzbekistan
Sri Lanka 480 Philippines 48 1 Belarus 482 Ukraine 484 Moldova 485 Armenia 486 Georgia 487 Kazakhstan 489 China Special Zone.
Basically, that's all that starts with 4. You can see if there is anything you are looking for.

Question 7: What do the bar code numbers stand for? The first three digits are country codes, and 690-695 stands for China. The last five digits are the manufacturer's code, which is the code given by the state to your enterprise. The next four digits are used as the product code, and different products must use different four digits. The last bit is the check code, which is automatically calculated according to the previous 12 bits.
book
This is EAN- 13 barcode, which belongs to commodity barcode.
But the first three digits are 978, which can be regarded as ISBN book code, that is, book code.
The last 10 digit belongs to the international standard book number and can be divided into three number segments.
7 107 190056 can be divided into three sections.
The first digit field is the area code, which consists of 1~5 digits, and 7 stands for China publications.
The second paragraph number is the publishing house code, which is assigned by the ISBN center of the country or region to which it belongs, and the allowable value range is 2~5 digits. The bigger the publishing house, the more books it publishes, and the smaller the number.
The book serial number (title identifier) is given by the publishing house itself, and the book serial number of each publishing house is fixed. The shortest one and the longest six. The bigger the publishing house, the more books published and the longer the serial number.
The tenth digit is the parity bit of the electronic computer. Fixed one digit, automatically generated by the first twelve digits.
