About Universal Product Code

[mstakh.i.mom.i]

A globally accepted sequence of unique numbers that correspond to the barcode that is assigned to a specific product is known as a Universal Product Code (UPC). When a barcode is scanned, it reveals important details about the product like the brand name, price, size, and other relevant data.

The UPC allows manufacturers and retailers to precisely track products in their inventory. A well-defined UPC with its batch lot enables any company to recall its damaged items or sold items easily. The UPCs are used by all warehouse tracking systems and point-of-sales systems to always have a record of all items. The idea of UPC is that it stays constant irrespective of who sells the product and where it was sold.
