Introduction To Barcodes

Barcodes for Retail Products

  • Barcodes are used on retail products to help retailers. They are used for scanning at the checkout, stock tracking etc. There are no legal requirements for retail barcodes. However, they do need to meet accepted retail industry standards.
  • There are 2 main types of retail barcodes:
    • EAN13 – 13 digit globally unique barcodes used in most countries outside the USA and Canada – can be used on products worldwide.
    • UPC (also called UPC-A) – 12 digit globally unique barcodes commonly used in the USA and Canada but can be used on products worldwide.
  • Our EAN13 and UPC barcode numbers can be used for any retail product except 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. However, this is ONLY a licensing arrangement, and you will typically be required to complete multi-page membership forms, pay to join fees and annual renewal fees and then wait for the approval. 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. You can’t just make up barcode numbers to use (unless you are ONLY selling your products within your own store). Barcode numbers need to be purchased or obtained from a legitimate barcode source.
  • There is NO product information encoded in retail barcodes. Barcode numbers are purely unique numbers, 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 retailers computer system so that the product information, pricing etc., show 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 scan the barcode or type the barcode number into their computer system. They will also enter the product information, e.g. 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 will require you to enter all of this information onto a form, which is then automatically entered into their computer system.
  • A different barcode number is needed for each unique product – and then you can sell thousands or millions of the same product with the same barcode number on it. For example, if you have 3 different products and each has 5 different colours, 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 your product packaging design. 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 sticky 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 that the NUMBER comes from the USA. We have thousands of customers using tens 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 originating from GS1 in your country. This is because they incorrectly believe that the first few digits of a barcode number show the product’s country of origin. This is untrue. 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 for cartons containing retail products. These cartons are used for shipping and 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 cartons for shipping and storage. If the carton is being sold at the retail level, it should have a retail barcode on it (EAN13 or UPC) rather than an ITF-14 barcode (e.g. a case of wine can be bought as a single unit by a customer. Therefore it would need a retail barcode – EAN13 or UPC).
    • ITF-14 barcodes are larger than retail barcodes and should have a heavy horizontal line on top and bottom.
