Introduction To Barcodes

Barcodes for Retail Products

  • Barcodes are used on retail products to help retailers (scanning at the checkout, stock tracking etc). There are no legal requirements for retail barcodes, but they do need to meet accepted industry standards.
  • There are three types of retail barcodes:
    • EAN13 – 13 digit globally unique barcodes used in most countries outside the USA and Canada. They can be used on products worldwide.
    • EAN8 – a smaller globally unique barcode intended for VERY SMALL products. These are only available from GS1 (a membership organization) and can be difficult to obtain, because with only 8-digits there are much fewer combinations and therefore fewer unique numbers to be assigned. To obtain these, you need to submit proof that your product is very small, and wait to see if GS1 approves your request.
    • UPC (also called UPC-A) – 12 digit globally unique barcodes commonly used in the USA and Canada (also usable on products worldwide).
  • Our EAN13 and UPC barcode numbers can be used for any retail product except for books & magazines.
  • Books require an ISBN, which is turned into an ISBN barcode (in EAN13 format).
  • Magazines require an ISSN number, which is turned into an ISSN barcode (in EAN13 format).
  • All legal retail barcodes (including ours) originate from the GS1 system. You can obtain your barcodes directly from GS1, but they provide barcodes ONLY under a licensing arrangement. You will typically be required to complete multi-page membership form, pay registration fees, annual renewal fees and go through an approval process. Alternatively, you can purchase your barcodes from a genuine barcode reseller company such as ourselves.
  • Retail barcode numbers are globally unique numbers and are protected. Barcode numbers cannot just be made up and used in retail (unless you are ONLY selling your products within your own store). Barcode numbers need to be purchased or obtained through a license arrangement. Obtaining a barcode number from a licensee organisation is usually VERY expensive.
  • There is NO product information encoded in retail barcodes. Barcode numbers function simply as unique number identifiers. They are, effectively drawn from a large international database and allocated to you. The bars of the barcode ONLY encode the number shown under the bars. Scanning the bars is just a quick way to enter the barcode number into a retailer’s computer system, so that the product information, pricing etc. shows up at the checkout.
  • Your retailer has to manually connect your barcode number to your product details within their system. When a retailer first receives your product, they will type the barcode number or scan the barcode into their computer system. They will also enter other product information, eg product name, description, retail price, supplier etc. After this, when the barcode is scanned at the checkout, the correct information will be displayed. Larger retailer chains may require you to enter all this information onto a form, which is then entered into their computer system automatically.
  • A different barcode number is needed for each unique product, but you can sell thousands or millions units of the same product with the same barcode number on it. For example, if you have three different products and each has five different colors, you will need 3 x 5 = 15 barcodes.
  • The best way to get a barcode onto your product is to incorporate the barcode image into the design of your product packaging. We supply the barcode images for printing on your product. If you have already printed your product packaging, then you can add a barcode using a separate label.
  • Barcode numbers say NOTHING about the country of origin of the product or the company. The first few digits of a barcode number ONLY show the country of origin of the BARCODE NUMBER. Our numbers start with 07 which shows the NUMBER comes from the USA. We have thousands of customers using hundreds of thousands of our barcodes in 100+ countries without any problems.
  • Our barcodes can be scanned by ALL retailers WORLDWIDE. However, a very small group of retailers have extra requirements that restrict barcodes. For details of barcode acceptance worldwide see
  • Our barcodes can be used in ALL countries, except possibly China. Some Chinese distributors insist that the products they distribute have a barcode number that originates from GS1 in your country. This is because they incorrectly believe that the first few digits of a barcode number show the country of origin of the product. This is untrue. Yes this unfortunate mistaken view can be very costly for some manufacturers who want to sell their products in China, as these Chinese distributors pressure the manufacturer to get GS1 barcodes – joining GS1 is time consuming and expensive, with joining fees and annual fees, plus lawyers and debt collectors if you don’t pay your renewal fees.
  • Retail barcodes do not need to be registered however you can register them if you want to. If you purchase retail barcodes (EAN or UPC) from our company, you will be able to register your barcode numbers & product details for free on the International Barcodes Database.


Barcodes for Cartons

  • Barcodes can be used on cartons containing retail products. These cartons are used for shipping or storage.
  • ITF-14 barcodes are the common barcodes for cartons.
    • These are 14 digit numbers based on the barcode number of the retail product inside the carton
    • These are ONLY for shipping and storage cartons. If the carton is being sold at retail level, it should have a retail barcode on it (EAN13 or UPC) rather than an ITF-14 barcode. For example six bottles of wine packaged together in a box could be sold as a single unit and would need a retail barcode (EAN13 or UPC).
    • These barcodes are larger than retail barcodes and should have a heavy horizontal line top and bottom.


QR Codes

  • QR codes are square barcodes that look a bit like a maze. They can contain information (e.g. a link to a website URL) encoded in a graphic format that can be accessed by scanners or smart phone apps.
  • QR codes can be used on retail products, BUT the product will ALSO need a retail barcode on it. The retail barcode is scanned by the retailer for pricing etc. at the checkout.

Barcodes Images

  • Barcodes can be created with many different encoding formats.
    • Some of these formats are suitable for retail products and books/magazines (EAN13, UPC-A, EAN8)
    • Some of these formats are useful for cartons (ITF-14 barcodes)
    • Some of these formats are useful for tracking pallets or shipping containers
    • Some of these formats are used for stock tracking and inventory purposes (e.g. for library books or asset labelling)
    • Some are two dimensional e.g. QR codes and contain information or links to website URLs
  • We can create barcodes in all of these formats
