UPC barcodes are the ones scanned at the cash register. There’s a UPC barcode on almost everything sold through the retail channel around the world.
UPC barcodes have distinct three sections: an assigned company prefix, a number that uniquely identifies the specific product, and a check digit at the end. The company prefix and item number total 11 digits in length. The 12th digit is the UPC check digit in the lower right corner and is based on the company prefix and item number.
UPC barcodes have a fixed length (12 digits)& a standardized format, and uniquely identify consumer items throughout the supply chain.
UPC version A & UPC version E bar codes are used in the US & Canada. EAN-8 & EAN-13 bar codes are used internationally with the exception of JAN-8 and JAN-13 which are used in Japan. ISBN-13 barcodes (the old Bookland barcode) based on ISBN numbers are used on books.
And why do I know so much about UPC barcodes let alone care? Because I own Azalea Software and we sell UPCTools among other things. I’m what you might call a “barcode nerd”. There, I said it.
Don’t get me started. I know more about barcodes than you want to hear. Believe you me, I can talk about bar codes for hours. Literally hours.
