What does the barcode on food represent? How many are there?

Food product barcodes.

Meaning: The standard commodity barcode consists of 13 digits and can be divided into 4 parts, from left to right (in China).

1--3 places: a total of 3 places, is the country of China**.

690--695 are all China's **, which is distributed internationally);

4--7 8 9 digits: a total of 4 5 6 digits, representing the manufacturer**, applied by each manufacturer, allocated by the state;

8 9 10-12 digits: a total of 3 4 5 digits, representing the goods in the factory**.

At the discretion of the manufacturer;

The 13th digit: a total of 1 digit, is the check code, according to a certain algorithm, from the first 12 digits, obtained by calculation, used to correct the reading error generated in the scanning process.

A food barcode is a standardized** used to identify and identify food, usually consisting of 13 digits. From left to right, they represent:

1.Prefix (1-3 digits): This is used to identify a country or region**, assigned by the International Article Number Association. For example, 00-09 represents the United States, Canada, and 69 represents Chinese mainland.

2.Manufacturer** (4-8 digits): Given to the manufacturer by the article coding organization of each country or region**. In China, the National Article Numbering Center is responsible for empowering manufacturers**.

3.Commodity ** (9-12 digits): determined by the product manufacturer and used to identify the product**.

4.Check code (13 digits): used to verify the correctness of the 1st to 12th digits** from the left in the product barcode.

Therefore, the barcode on food usually consists of 13 digits and is used to identify the standardization of food**.

13-bit. The barcode of goods is generally divided into 4 parts, according to 3-5-4-1 points, the first part represents the country, the second part represents the manufacturer, the third part represents the goods in the factory, and the fourth part is the validity code:

Take the barcode 6936983800013 as an example, this barcode is divided into 4 parts, from left to right:

1-3 digits: a total of 3 digits, corresponding to the barcode of 693, is one of the national ** in China. (690--699 are all China's **, which is distributed internationally).

4-8 digits: a total of 5 digits, corresponding to the barcode of 69838, on behalf of the manufacturer**, applied by the manufacturer, allocated by the state.

9-12 digits: a total of 4 digits, corresponding to the barcode 0001, representing the goods in the factory, determined by the manufacturer.

The 13th digit: a total of 1 digits, corresponding to the 3 of the barcode, is the check code, according to a certain algorithm (generally using barcode software, the last check code automatically pops up by the software system), calculated by the first 12 digits.

The coding of the commodity barcode follows the principle of uniqueness to ensure that the commodity barcode is not repeated in the world, that is, a commodity item can only have one, or one can only identify one commodity item. Different specifications, different packaging, different varieties, different **, different colors of goods can only use different products**.

EAN commodity barcode, also known as universal commodity barcode, is developed by the International Article Number Association, commonly used all over the world, and is currently the most widely used commodity barcode in the world. There are two types of EAN product barcodes: EAN 13 (standard version) and EAN 8 (shortened version).

The EAN 13 generic product barcode generally consists of a prefix part, a manufacturer**, a product**, and a check digit. The prefix code in the commodity barcode is used to identify the country or region, and the right to assign the code is in the International Article Numbering Association, such as 00-09 on behalf of the United States, Canada on behalf of Japan.

69 represents Chinese mainland, 471 represents Taiwan, and 489 represents Hong Kong SAR. The empowerment of manufacturers is in the article coding organization of various countries or regions, and China is given to manufacturers by the National Article Coding Center. Commodities are used to identify goods, and the right to assign codes is exercised by the product manufacturers themselves, and the manufacturers decide which Arabic numerals are used for the commodity barcodes in accordance with the prescribed conditions.

At the end of the product barcode, a 1-digit check code is used to verify the correctness of the 12th digit ** from the left in the product barcode.

For details, please refer to the product barcode encyclopedia.

13-bit. The first two digits represent the international code, 7 digits represent the manufacturer**, 3 digits represent the product code (the manufacturer compiles itself), and the last digit is the check code (automatically generated by the computer system).

The barcode of food is a graphic identifier that combines a plurality of black bars and blanks of 2 widths and arranges them according to certain coding rules to express a set of information. A common barcode is a pattern of parallel lines arranged by black bars (referred to as strips) and white bars (referred to as blanks) with very different reflectivity. The barcode can indicate the country of manufacture, manufacturer, product name, date of manufacture, book classification number, mail origin, category, date, and many other information.

The food barcode is composed of thirteen numbers, these numbers will not seem to have any connection, in fact, they are very linked, and they are divided into four layers of meaning, as long as you understand it, it is very simple. The barcode should be checked from left to right, first of all, one to three digits, three digits, this number has a range, China only has a number in the range of "690--695", because this is the ** in China, which is assigned by the world to China. After that, we need to look at the number of four to eight digits, a five-digit number, these five are another layer of meaning, this is the number is the five numbers that the manufacturer applied for from the state, and it is the special ** of the business, which represents a symbol of the manufacturer, and we must pay attention to it.

Meaning of commodity barcode:
