Introduction to Barcodes

What is a Barcode?

A barcode is a symbol that can be easily read by a scanner or smartphone. Barcodes link to a globally unique number. Retailers use this number to enter product information into their database. Barcodes do not contain information. They just represent the number. Barcodes are most commonly used at store checkouts to quickly retrieve the name and price of a product. Barcodes also track products as they move through the supply chain. Once scanned, the store can be alerted to low stock levels of a particular item. This prompts the store to reorder. Every variation of a product (e.g. each size and colour) requires its own barcode.

Do I Need a Barcode?

If you have a product you wish to be stocked at a retail store, you will almost certainly need barcodes. Different retailers and regions have varying standards. It is important to pick the right barcode type to avoid unnecessary hassle and confusion when your products arrive in store. Each product and variation will require its own unique barcode. For example, if you have three different products, and each has five different colours, you will need 3 x 5 = 15 barcodes.

Types of Barcodes

Retail Barcodes


EAN 13

EAN-13 Barcodes / International Article Number

International Article Numbers, formerly EAN (European Article Numbers), are 13 digits long. They are used worldwide on all retail products, excluding books and magazines. They are the most widely used barcodes globally. The USA and Canada prefer UPC-A (Universal Product Codes) barcodes. In the UK, EAN-13 is probably the barcode you need for selling retail products in the UK.


The EAN-13 number is encoded into a barcode image. When the barcode is scanned into store systems, price and inventory data related to your product are recorded by the retailer. A different EAN-13 number, therefore, is required for each unique product(SKU). Click Here to purchase EAN-13 barcodes.

UPC-A Barcodes

12-digit UPC Barcodes are used predominantly in the USA and Canada on all retail products, except for books and magazines. If you are selling in the US or Canada, you may want to use a UPC-A code rather than an EAN-13 code. Click Here to purchase UPC-A barcodes.






EAN 8 EAN8 Barcodes

A smaller, globally unique barcode intended for VERY SMALL products. EAN8 barcodes are difficult to obtain. They are only available from GS1. GS1 is a membership organisation. EAN8 barcodes are only eight digits long. This means that there is a limited number of them. Hence GS1 guard them carefully. So to obtain these, you need to submit proof that your product is very small and wait to see if GS1 approve.




Book and Magazine Barcodes


ISBN barcodeISBN Book Barcodes

International Standard Book Numbers (ISBN) barcodes are used on all book formats.  A hardcover would need a different ISBN number to a paperback or e-book. ISBNs usually start with 978 or 979. ISBNs are distributed by ISBN agencies in each country (see They can also be obtained through independent publishing agencies such as, used for self-publishing authors. Note: Crossword, puzzle and colouring books are not published books, so do not use ISBN barcodes. They use standard retail barcodes instead (EAN or UPC).

We cannot provide you with an ISBN. Only your national ISBN issuer can give you the ISBN number. Nielsen controls ISBN distribution. You can also get an ISBN from the Independent Publishing Network. What we do is make the ISBN barcode image once you have received your ISBN. Click Here for more information.

Carton Barcodes


ITF 14ITF-14 Carton & Pallet Barcodes

EAN and UPC barcode numbers make the  ITF14 carton number. Carton codes are only used in warehouses on wholesale cartons containing a specific quantity of the product barcode represents. Point-of-sale systems do not use carton codes.  For example, a case of wine sold as a single unit would need a retail barcode. You may need an ITF-14 code if you have a shipping carton of wine bottles that are being taken out and sold individually after they arrive at the shop. Click Here to purchase ITF-14 barcodes.

Quick Response Codes

QR Codes are square barcodes. They can link to a website URL or contain information. QR codes are often used on posters, pamphlets, and advertising material. You can also use them on retail products, for example, to take a customer to your website. However, the product will also need a retail barcode on it, scanned by the retailer for pricing etc., at the checkout. Click Here for more information about our QR code services.



How to Use Your Barcode

Barcode products in 3 easy steps:

1. Buy a barcode:

• Establish where you will be selling your product to determine if you require EAN-13 or UPC barcodes.
• Decide how many barcodes you need. Remember that each different size, colour and flavour requires a different barcode number.
• Purchase your EAN or UPC barcode on our website.
• Receive an email with your barcode number/s with the barcode images in 4 image formats.


2. Add your barcode to your product:

• Choose whichever barcode image format (e.g. jpeg, pdf) you prefer.
• Resize the image to fit into your product packaging. Please keep in mind the Barcode Dimensions: The standard size is about 38mm wide x 25mm high. The smallest recommended size is 80% of the standard size – i.e. about 30mm wide x 20mm high.
• Add the barcode to your product packaging in an easily visible, flat location. Don’t print too close to the edge or over any seams.

  • Positioning on a curved surface, e.g. a bottle, it is best to rotate the barcode. i.e. like a ladder (vertical) instead of a fence (horizontal).
  • You can print the barcode onto adhesive labels. You can then stick the barcode labels onto your product. Follow the same principles outlined above.
  • Check your label artwork BEFORE printing your product packaging.
  • Ensure the barcode numbers are correct. The barcode image should be high quality and within the official size range.
  • Do a sample print.
  • Check that the barcode prints and scans correctly.


3. Send your product to retailers:

Send the barcoded products and product information to your retailers. The retailer will scan the barcode into their system. Stores enter the specific product name and price into their database. Your product information will now appear in the store database.
