What does the number on the barcode mean?

The barcode of the product refers to a symbol of a logo, empty, and corresponding characters arranged by a set of rules to represent a certain product information. Among them, the strips are dark, empty, and are used for scanning and reading of strip code reading equipment. Its corresponding characters are composed of a set of Arabic numerals for people to read or use the keyboard to use the keyboard to enter the computer. The information of this set of emptiness is the same as the corresponding characters. Barcode technology is born and applied with the development and application of computers and information technology. It is a new type of technology that combines coding, printing, identification, data collection and processing. The use of barcode scanning is the general trend of market circulation in the future. In order to enable goods to be free and widely circulated around the world, whether it is design and production, whether it is designing and making, applying for registration or using the product barcode, must follow the relevant provisions of the barcode management of the product. At present, the common code systems in the world include ENA barcodes, UPC barcodes, two or five codes, cross two or five codes, Kurdba barcodes, three nine -nine strips, and 128 barcodes. The most commonly used products are EAN product barcodes. EAN Commodity Barcode is also known as General Commodity Bar Code. It is formulated by the International Article Code Association and is commonly used in all parts of the world. It is currently the most widely used product barcode in the world. This kind of commodity barcode is currently used in my country in China. EAN product barcode is divided into EAN -13 (standard version) and EAN -8 (shortened version). EAN -13 General Commodity barcode is generally composed of prefix parts, manufacturer code, product code, and school inspection code. The prefix code in the barcode of the product is used to identify the code of the country or region. The code right is an international item coding association, such as 00-09 represents the United States and Canada. 45-49 represents Japan. 690-692 represents mainland China, 471 represents Taiwan, my country, and 489 represents the Hong Kong Special Administrative Region. The power of manufacturer code is an item coding organization in various countries or regions, and my country is given a manufacturer code by the National Item Code Center. Commodity code is the code used to identify the product. The right to be exercised by the product production enterprise itself. The manufacturer is based on the requirements of the Arabic numerals to use the product barcodes on the product. The product barcode was finally used to check the correctness of the L -12 digital code from the left in the barcode of the product. The coding of the product barcode follows the unique principle to ensure that the barcode of the product is not duplicated worldwide, that is, a commodity project can only have one code, or a code can only identify one commodity project. Different specifications, different packaging, different varieties, different prices, and different colors of products can only use different product code. The standard size of the product barcode is 37.29mm x 26.26mm, and the magnifying rate is 0.8-2.0. When the printing area allows, the barcode of more than 1.0 times should be selected to meet the requirements of learning. The smaller the barcode of the magnification, the higher the printing accuracy requirements. When the printing accuracy cannot meet the requirements, it is easy to cause the barcode to read difficulty. Because the reading of barcodes is achieved by the colors of the barcode and the color contrast of the empty code. Generally, as long as it can meet the color of the requirements of the contrast (PCS value), it can be used. Light colors are usually used as white, orange, yellow, etc., with dark colors, such as black, dark green, dark brown, etc. The best color matching is black and white. According to the practical experience of barcode detection, red, gold, and light yellow should not be used as strips, and transparent and gold cannot be empty. EAN -8 commodity barcode refers to the bar code with 8 -bit commodity code used for the logo, which is composed of a product code represented by 7 digits and a 1 -digit inspection symbol. The birth of the product barcode has greatly facilitated the circulation of commodities. Modern society is inseparable from the barcode of the commodity. According to statistics, there are currently 500,000 products in my country that use the international commodity barcode. After my country's Canadian World Trade Organization, companies will win more space for activity on the international stage. It is necessary to be in line with international practice and meet the needs of international economic and trade. The barcodes of barcodes of members in some countries and regions (EAM) are in the United States, Canada 00-09 Israel 729 Denmark 57 (in-shop code) 20-29 Venezuela 759 Norway 70 Japan 45-49 Uruguay 773 Switzerland 76 Belgium/Luxembn 54 Bolivia 773 Spain 64 64 Chile 780 Austria 90-91 Sweden 73 Ecuador 786 New Zealand 94 Italy 850 Sloven 383 Dutch 87th Czech 859 Germany 400-440 Australia 880 Taiwan 471 Bulgaria 380 Singapore 888 Lativia 385 Malaysia 4793 Sri Lanka越南977 香港489 爱沙尼亚474 墨西哥750 塞浦路斯529 立陶宛477 哥伦比亚770 马耳他535 菲律宾480 秘鲁775 葡萄牙560 希腊520 阿根廷779 波兰590 马其顿531 巴拉圭784 匈牙利599 爱尔兰539 巴西789 毛里求斯609 冰岛569 斯洛伐克858 阿尔巴尼亚613 罗马尼亚594 南斯拉夫860 Mainland China 690-692 South Africa 600-601 Thailand 885 France 30-37 Morocco 611 India 890 UK 50 Turkey 619, 869 Indonesia 899

The significance of 13 digits in the barcode chart is: the first three digits show the production area (country) of the product. The next 4 -digit number represents the business number of the manufacturer, which is uniformly mixed to the application for the application of the application agency in the country (or region). The next 5 digits are individual goods numbers. The manufacturers will first divide the products in different categories, and then encode one by one. The manufacturer can encode 100,000 items in total. The last number is the final check code, which is convenient for the scanner to check the entire encoding to avoid misunderstanding
