Commodity bar code three coding principles, do you know?

As an "ID card" for the free circulation of commodities around the world, barcode has been widely used in more than 150 countries and regions. Item coding and automatic identification technology has been widely used in retail, manufacturing, logistics, e-commerce, mobile commerce, e-government, medical and health, product quality traceability, books, audio and video and many other fields of national economic and social development.

When the product is ready for sale, the enterprise will code its product. At this time, it is necessary to understand the three coding principles of commodity bar code, namely, the principle of uniqueness, stability and no meaning. What are the characteristics of each?

uniqueness

The principle of uniqueness is the basic principle of commodity coding, which means that the same commodity should be assigned the same commodity code. Commodities with the same basic characteristics are regarded as the same commodity. Different commodities must be assigned different commodity codes, and commodities with different basic characteristics are regarded as different commodities. The basic characteristics of a commodity refer to its name, trademark, type, specification, quantity, composition, packaging type, etc. It should be noted that the commodity bar code has nothing to do with the price of the commodity, only related to the basic characteristics of the commodity.

The stability of

Stability principle refers to the commodity identification code once allocated, as long as the basic characteristics of the commodity has not changed, it should remain unchanged. The same commodity whether long-term continuous production or discontinuous production, must adopt the same commodity code. When the production of the commodity is stopped or removed from the shelves, the bar code can be used on other commodities (except for special circumstances and products) after 48 months in general. When calculating when the product is discontinued, off the market and the barcode of commodity can be used again, enterprises can log in to the China Commodity Information Service Platform of China Article Coding Center to timely register the products that have been off the market. When the barcode is used again, they can inquire details through the system of the above platform.

There was no meaning

The principle of meaninglessness is that each digit in the commodity code does not indicate any specific information about the commodity. Meaningful code usually results in a loss of coding capacity. Enterprises in the preparation of commodity bar code, the best use of meaningless serial number. The enterprise should timely report the product information on the commodity information service platform of the coding center to facilitate the enterprise to carry out scientific management of the commodity bar number.

Since its birth, commodity bar code has not only facilitated the circulation of commodities, but also promoted economic development and trade exchanges. Enterprises should seriously abide by the coding principle and make good use of commodity bar code.
