To obtain a barcode for your product (or book, or event) you need to reach one of these organizations and receive a bar code data (a number or a set of numeric-alphabet codes). Here's a complete list.Where to get a barcode? Barcodes are issued by specific certified organizations - barcode providers: If your prefix is from outside the United States, it doesn't start with 0. So, you can make the same barcode in an EAN-13 by simply adding the 0 yourself. A UPC-A's first encoded digit (hidden in the text below the barcode for a UPC-A) is always 0. These barcodes, despite having different names, are actually exactly the same in terms of the bar pattern – they're both 13-digit barcodes. UPC-A barcodes (12 digits) are typically used in the United States and Canada EAN-13 barcodes (13 digits) are used everywhere else in the world. Do I want a UPC or an EAN? How do I convert between the two? In general, you should leave the height at its default option unless there's some specific reason to change it. We provide this option because it a) is very widely and successfully used in the global market on small labels, and b) does not affect the scanability of the barcode. Technically, adjusting the height of a UPC/EAN can be considered a violation of generally accepted standards for UPC/EAN generation when used in environments governed by GS1, a retail standards organization. Adjusting the height of the barcode does not affect its scanability because the width is not affected by this change. Shorter barcodes are, for example, very commonly used in size restricted situations. How does UPC/EAN barcode height adjustment work?īarcode Producer can make your barcode shorter or taller than the default, internationally accepted default size using the Bar Height option. If you enter the wrong check digit, Barcode Producer will ignore your incorrect input and enter the correct check digit. You can also verify the correct check digit using GS1’s check digit calculator. Barcode Producer automatically calculates this for you so that an incorrect check digit can’t be used (thereby rendering an invalid barcode). The last digit of all UPC, ISBN and EAN barcodes is called a check digit. Why is the last digit of my retail barcode wrong? So, your number comes from somewhere else, and Barcode Producer turns that number into a scannable barcode. Once you have a UPC/EAN barcode value, you can enter that number into Barcode Producer to generate your barcode. You can easily find all sorts of these kinds of companies online. Get a single barcode value from a company that already owns a prefix and will sell you one of their barcodes.Use the prefix that your company already owns and produce a barcode for a new unique number under that prefix.You pay them an annual or one-time fee to reserve a barcode prefix – the first part of your UPC is the prefix, then the remaining numbers are the number that you assign to a particular item. In other countries, there's generally a local chapter of GS1. Register with GS1, the regulatory agency for UPC/EAN barcodes in the United States.If you don't have a barcode value already, there are a few ways to get a unique barcode value for your product: ![]()
