How to Create a Barcode

Three Methods:

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. Understand how barcodes work.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. Register your business with GS1.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 , read the guide, clickFill out GS1 Company Prefix Application, and follow the instructions.
  3. Determine the type of barcode you need.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.
    • 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.

Using an Online Generator

  1. Open the TEC-IT site.Go to in your browser. The TEC-IT site has a free barcode generator here.
  2. SelectEAN / UPC.On the left side of the page, you'll see a list of barcode types. Scroll down until you see theEAN / UPCheading, 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. Select a barcode variation.Click one of the barcode options below theEAN / UPCheading.
    • For example: to create a 13-digit EAN code, you'd clickEAN-13here.
  4. Delete the "Data" sample text.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. Enter your company's prefix.Type the prefix given to you by GS1 into the "Data" text box.
  6. Enter your product number.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. ClickRefresh.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. ClickDownload.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.

Using Microsoft Office

  1. Understand the limitations.You can create a CODE128 barcode in Microsoft Office, but you cannot create UPC or EAN codes. This shouldn't be a problem if you have the ability to scan CODE128 barcodes, but if you're reliant on UPC or EAN scanners, instead.
