1, a commodity barcode is just a barcode generated by a series of commodity code numbers. As long as there is corresponding commodity coding data, it can be generated in batches by barcode printing software. There is no truth in itself, but the goods in the package exist. 2. Scanning product barcodes with mobile phones and the product information of product barcodes that can't be found on the website of China Commodity Coding Center doesn't mean that the products are fakes, because commodity production enterprises will transmit their product barcodes to the background database of National Commodity Coding Center after a long period of time after applying for them at their local quality inspection and quarantine bureau. If you find the bar code of the product within this time, you can't find it. 3. There is a time limit for the use of commodity bar codes. Enterprises need to update bar codes every year before they can continue to use them. During the validity period, scanning the barcode can scan the product information. If the company does not renew the barcode after the expiration, you will be prompted that "product information cannot be found" and the corresponding product information cannot be found, but this does not mean that the goods are fakes. In addition, regarding the content of the inquiry, you can simply say that some bar codes can only inquire about the simple commodity name and manufacturer after scanning, and some can see more detailed information. This situation is normal, because manufacturers only apply for country code and manufacturer code when applying for commodity bar code, and others need to code themselves. When uploading commodity information in the background of China Commodity Coding Center, you can only find out what information the enterprise has set when scanning commodity bar codes.
