Note:
In order to generate a unique 12-digit UPC barcode, the barcode number needs to have originated from an authorized GS1- barcode seller such as Buyabarcode.com or GS1. If you are simply making this number up out of thin air it will not be able to be used in any type of retail store – (i.e. Amazon, Best Buy, Walmart, etc.)

BARCODE PRINTING INSTRUCTIONS:
In the current format your barcode can be printed onto stickers (at 300 dpi or greater) or placed directly into the artwork of your packaging / label. If you re-size the barcode, make sure it is a minimum of one inch in length from the left edge of the left bar to the right edge of the right bar.  The height of the barcode can be cropped as short as you wish to make it.

Why did the far right number of my UPC barcode number change?
All UPC barcodes are created using an algorithm embedded in the UPC font that automatically calculates the far right digit of the barcode. This 12 th digit is caIled the Check Sum digit and it is based upon a summation of the first 11 digits. If the 12 th digit of your barcode changed after you generated your barcode it is because the number you input was not the same as what was automatically generated by the embedded algorithm. Please know that the one automatically generated is actually the correct number in order for your barcode number to be a legitimate UPC barcode number.

What is a UPC Barcode?
A UPC Barcode (aka Universal Product Code) is simply a 12-digit number that nobody else in the world has. All UPC barcodes originate from a company called GS1 and they can only be sold by GS1 authorized sellers such as Buyabarcode.com. This is how you can know that nobody else in the world will have your 12-digit number. There is no information actually stored or encrypted in a UPC barcode. To state it once again, a UPC barcode is simply a 12-digit number that no one else in the world has.

How Do UPC Barcodes Work?
UPC barcodes are primarily used by retailers for inventory tracking. When you go to sell your product at a store, that store will have you fill out a product information form. This form is where you will place your company and product details as well as your 12- digit UPC barcode number.  The store then enters this information into their inventory management system and that way, when they scan your UPC barcode at the register, it calls up that form in their system.
