This wikiHow teaches you how to create a barcode for use on a product. After signing up for a GS1 prefix for your barcodes, you can create UPC or EAN barcodes one at a time by using an online generator, or you can create a printable list of CODE128 barcodes using Microsoft Excel and Microsoft Word.

Preparing to Create

  1. A barcode contains two sets of numbers—a global prefix that identifies your business, and a product serial number—that allows you to bring up a product's information by scanning the code.
    • If your products don't have individual serial numbers yet, you'll need to set up a product list in your preferred point of sale program before you can create relevant barcodes.
  2. . GS1 is a not-for-profit company that maintains the global standards for barcodes. After registering your company with GS1, you will receive a "prefix" set of numbers that you can use to refer to your company at the beginning of each barcode.
    • To register with GS1, go to the GS1 U.S. page , read the guide, click Fill out GS1 Company Prefix Application , and follow the instructions.
    • GS is the main kind of worldwide barcoding system. We use it on the products. You have to buy a barcode for your category or company. They are available in denominations of one to thousands.
    • There are some companies online that try to resell them. You can buy 100 for 15 bucks. But those are not legitimate barcodes.
    • If you purchase more barcodes, they may be cheaper.

  3. Most businesses will use either UPC (North America, U.K., New Zealand, and Australia) or EAN (parts of Europe, Asia, Africa, and Latin America) barcodes. [1]
    • There are other types of barcodes (e.g., CODE39 and CODE128) as well.
    • Different versions of barcodes support varying lengths of product numbers. For example, EAN-8 barcodes support up to 8 numbers to identify your business and a product, while EAN-13 codes support up to 13.
  4. Make sure that you have an inventory list on-hand. Before you create a product's barcode, you'll need to know the number that you use to identify that product in your business' point of sale program. It can be a hassle to dig up this information for each product individually, so have your product information sheet available if possible.

  1. Go to https://barcode.tec-it.com/en in your browser. The TEC-IT site has a free barcode generator here.
  2. On the left side of the page, you'll see a list of barcode types. Scroll down until you see the EAN / UPC heading, then click it to expand it.
    • Your mouse cursor must be over the list of barcode categories when you scroll.
    • If you want to create a different type of barcode, click that type of barcode instead.
  3. Click one of the barcode options below the EAN / UPC heading.
    • For example: to create a 13-digit EAN code, you'd click EAN-13 here.
  4. In the large text box to the right of the list of barcode categories, delete the text that appears after selecting a barcode type.
  5. Type the prefix given to you by GS1 into the "Data" text box.
  6. In the same box as the prefix, type in the number that you use for your product.
    • There shouldn't be a space between the prefix and the product number.
  7. This link is below the bottom-right corner of the "Data" text box. Doing so will update the barcode preview on the right side of the page with your prefix and product number.
    • If you see an error in the barcode preview box, try re-entering your barcode or selecting a different barcode format.
  8. It's on the right side of the page. The barcode will download into your computer's default "Downloads" location; once it finishes downloading, you'll be able to print it out and place it on the appropriate product.
