![]() Eric Woods says, “If we're not doing barcoding, we're doing clipboard and pen, and we're losing inventory. Doing so may uncover problems that need to be fixed before implementing a change. No prescribed length, but generally 8 charactersįirst, assess your current inventory management processes. UPC is 12 characters, EAN is 13 there are variations and add-ons for certain situations Using a GS1-assigned company prefix, manufacturers add a product number, and then calculate the check digit, which creates the final UPCĬompanies can assign any set of characters (numeric, alphanumeric, section, etc.) as a SKU ![]() UPC-A is the most common encoding scheme in North America, EAN-13 in the rest of the world Manufacturers register with GS1 and are assigned a company prefix for use in their UPCs Organizations can create them manually (by entering the required numbers into a barcode creation tool) or automatically by using a software package. Businesses can use UPCs as SKUs, but internal SKUs offer more flexibility. Because SKUs are internal, companies don’t register them with a central organization. The UPC standard includes a manufacturer code, a product code, and a check digit (which helps verify that the code was scanned correctly).Ī SKU is internal to a company and helps companies keep tabs on items in stock from the moment they are received until they are sold. No other company can use the UPC for their product (this helps to protect the brand). Customers and potential customers can use the UPC to research and compare product prices across websites. By working through a centralized organization, manufacturers and vendors can sell their products in many places, including online. UPCs are coordinated through an organization called GS1 (GS stands for global standard). While both UPCs and SKUs are generally barcodes, they serve different purposes. UPC (Universal Product Code) and SKU (Stock Keeping Unit) are terms used in retail. Likewise, when you scan a barcode on an item in a business’s warehouse, you’ll receive information on the product itself, whether it’s red XL t-shirt or a replacement piston for a tugboat engine. However, the number is stored in a database and refers to your car’s registration information (including your name and address), any outstanding tickets, and more. ABC123 (an example plate number) has no real connection to what make, model, or year a car is or who owns it. You can think of a barcode as you would the license plate on a car. When a product is placed in the location, a worker can scan both the product and the location codes, and the inventory system will record the location data. They can associate several data points to the number, including the supplier, product dimensions, weight, and even variable data, such as how many are in stock.īarcodes can also be assigned to locations, such as a bin on a shelf in a warehouse or stockroom.
