What is the difference between upc and upc

The barcode is used by scanners to read the black, vertical lines of various widths and the width of the bars represents a number. When a product is sold through another channel such as a retailer or online marketplace like eBay or Amazon , they are often required to have a unique number which is the UPC. This unique number differentiates one unique product from another. When a product is shipped to a distributor or retailer to resell, they often generate a SKU to internally better manage that item in their inventory system.

Barcodes may look like a random assortment of lines and numbers. The vertical lines are used so scanners can read the information, but those lines are associated with the numbers which provide some information.

The UPC is a series of 12 numbers and are broken into the company prefix, item reference number and a check digit. These numbers are a unique number assigned to a company. This number is assigned by the company to the individual product the UPC is being created for.

This number would be different for each variant of the product like size, color, etc. The last digit on a barcode label is called a check digit. The check digit detects errors in the code through a calculation. This helps ensure the other numbers on the barcode are correct. There are a few different ways to get a UPC code for a product. The free barcode option is really only useful if you are selling your own products through your own website and maybe some local stores.

If you are selling a product at a larger retail store, through most distributors or online marketplaces, a GS1 Global Standard 1 certified UPC is required. GS1 UPCs are managed through a non-profit organization that ensures each barcode is unique globally, which is critical in keeping products moving from the manufacturer to the final customer. There are two options for getting a GS1 barcode. One is to purchase directly from GS1. This option provides a code that is totally unique to the manufacturer.

This guarantees that the code is yours and all retailers and marketplaces will accept it. It does come at a cost. Amazon has even warned that they may enforce in the future. The second option is to purchase a GS1 certified barcode from a reseller. Many retailers, especially smaller retailers may be using older inventory systems that only allow them to enter only 12 digit UPC numbers and not a 13 digit string.

If this changes in the future, you can convert your 12 digit UPC to a 13 digit EAN by adding the country code of 0 to the beginning. This following information was originally authored by George Laurer, the inventor of the UPC barcode. Version A symbol and the EAN13 symbol are essentially one and the same. They both have the same number of bars and spaces.

When I conceived the U. Each printed character has two bars and two spaces and is made up of 7 modules. Odd parity simply means the printed representation of the numeric digit has an odd number of dark modules. Conversely even parity printed digits have an even number of dark modules. The 10 characters identifying the manufacturer and item were printed below the bars. Further, they chose to carry only 10 digits of the number in their files. The reason was both political and practical.

Before the symbol marking was considered a well know consulting firm had been hired by the fledgling UCC to determine the number of digits needed to accomplish the goals of the grocery industry. Considering many factors, not the least of which was the limited power of computers of the day, a figure of 10 digits was recommended.
