Introduction to Barcodes

What is a Barcode?

A barcode is a symbol that a barcode scanner or smartphone app can easily read. Barcodes encode a number. Retailers use this number to enter product information into their database. The barcode itself doesn’t contain product information, just the number. Barcodes are most commonly used at retail store checkouts to quickly retrieve product name and price. Additionally, barcodes track products as they move through the supply chain. Once scanned, store owners can be alerted to low stock levels of a particular item, prompting them to reorder in good time. Every variation of a product (e.g. each size and colour) requires its own barcode. For more detailed information about the history and current use of barcodes, Click Here

Do I Need a Barcode?

Most retailers will require your products to be barcoded. Different retailers and regions have varying standards, and it is important to pick the right barcode type to avoid unnecessary hassle and confusion when your goods make it to a 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), comprise 13 digits. They are used worldwide on all retail products excluding books and magazines. EAN-13 barcode format is the most widely used format globally, with the exception of in the USA and Canada, where UPC-A (Universal Product Codes) barcodes are more common. In Ireland, the EAN-13 is probably the barcode you need if you have products you wish to stock at a retail store.

Each EAN-13 is product-specific and encoded into a barcode image. This means that when the barcode is scanned into store systems, price and inventory data related to your product is recorded by the retailer. A different EAN-13 number, therefore, is required for each unique product. 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, with the exception of books and magazines. If you are selling in the US or Canada, you likely want to use a UPC-A code rather than an EAN-13 code. Click Here to purchase UPC-A barcodes.






EAN 8EAN8 Barcodes

A smaller globally unique barcode intended for VERY SMALL products – difficult to obtain and 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, and 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 this.




Book and Magazine Barcodes


ISBN barcodeISBN Book Barcodes

International Standard Book Numbers (ISBN) are barcodes for both hard copy and e-books. ISBNs usually start with 978. We cannot provide you with an ISBN number. Ireland doesn’t have its own ISBN agency.

If you don’t have an ISBN number yet, we know of 2 main options –

1. You can get a single ISBN number for £30.00 through the Independent Publishing Network.

2. Alternatively, you can get one from Nielsen ISBN Agency. This will cost you £89.00 for a single ISBN number.

Note: Crossword, puzzle and colouring books are not published books. They do not use ISBN barcodes, they use standard retail barcodes instead (EAN or UPC).





ISSN Magazine Barcodes

An International Standard Serial Number (ISSN) is a unique 8-digit number. ISSNs identify periodical publications such as magazines and journals. They can be applied for at the Irish ISSN Centre.
Only apply for an ISSN if your publications meet the following criteria:
• They are serials (journals, newspapers, magazines, monographic series etc.)
• They are ongoing integrating resources (websites, databases etc.)

Carton Barcodes


ITF 14ITF-14 Carton & Pallet Barcodes

ITF-14 Carton Codes are created from EAN-13 and UPC-A barcodes. They are only used in warehouses on cartons containing a specific quantity of the item that the product barcode represents. These codes are not for products that are sold individually at a retail level. For example, a case of wine which is sold as a single unit would need a retail barcode. You may need an ITF-14 code if you have a shipping carton full of wine bottles which will be taken out and sold individually after they arrive at the shop. Click Here to purchase ITF-14 barcodes.


QR Codes

Quick Response Codes

QR Codes are square barcodes that look a bit like a maze. They can be used to link to a website URL or to contain information. They 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, which is 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

Getting barcodes onto your products and into retail stores involves three 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 based on product variations. Remember that different sizes, colours and flavours each require separate barcodes.
• Purchase your EAN or UPC barcode in the correct quantity online.
• Receive an email with your barcode number/s plus files with the corresponding images in the file format of your choice.


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: 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. For full specifications, see:
• Add the barcode to your product packaging in an easily visible, flat location. Don’t print too close to the edge or over the seams.

packaging design tips barcode placement


If you are placing your barcode on a curved surface, e.g. a bottle, rotate the barcode to resemble a ladder (vertical) instead of a fence (horizontal).
Check your label artwork BEFORE printing your product packaging (barcode numbers are correct, and the barcode image is of high quality and within the official size range).
We highly recommend you Do a SAMPLE PRINT and check that the barcode prints and scans correctly.


3. Send your product to retailers:

Once you’ve printed your product packaging, send the barcoded products and product information to your retailers. The retailer will scan the barcode into their system and enter the specific product and price information for that item into their database. Product information will now appear whenever the barcode is scanned in that retail store.
