Frequently Asked Questions

A ‘barcode picture’ is a machine-readable image consisting of vertical black bars and spaces of variable widths. When scanned by a barcode scanner, the black bars and spaces are decoded to reveal a specific 12- or 13- digit long sequence of numbers (the ‘barcode number’).

The 12-digit UPC bar code system was designed in the early 1970s by George J. Laurer in the USA (when he was working as an engineer for IBM). A few years later he developed a 13 digit version of this code, the EAN-13 code, for use internationally (outside of the USA).

EAN-13 barcode numbers are 13 digits long. They are the most common type of barcode for retail products in Ireland (as well as worldwide). In the USA, the 12-digit UPC code is preferred. Almost all barcode scanners are able to read both types of code. If you want your barcode in UPC-A format instead (or as well), that’s fine; just let us know when you make your order.

Most retail stores use a barcode system, therefore we recommend that you get a barcode if you want to sell your product in retail stores. You may also need a barcode if you want to sell your product online. Stores such as Amazon and CD Baby require your product to have a barcode.

Barcode Packages ordered through our company are sent via email with the guarantee and images (in 4 different formats – .eps, bitmap, tiff, jpeg & PDF) as attached files. You can then get your printer or designer to incorporate one of the images into your product packaging (or do this yourself). This needs to be incorporated in easily visible, flat locations – ensuring there is a sufficient amount of white space on either side of the barcode, as per the barcode specifications.

Alternatively, we can also provide you with sticky barcode labels that can be stuck onto your product (you can order sticky barcode labels here).

Yes, you can – just let us know what you want when you make your order. We normally provide barcodes in EAN-13 format because this is the most common format used in Ireland – however, we are happy to supply your barcode to you in UPC-A format instead (or as well), if you prefer. UPC barcodes are 12 digits long and are used mainly in the USA. EAN barcodes are usually 13 digits long, and they are used all over the world. Most barcode scanners can read both types of barcodes.

It is usually necessary to have a different EAN-13 barcode for each different product variation (each different size, colour, design etc). Certain products, such as greeting cards or postcards, sometimes use just one barcode number (although often with a 2-digit supplement at the end – ie. EAN13+2 format).

The bar codes that we supply are GS1-origin barcodes that are unique worldwide. They are suitable for use on any retail product (although if you have a book or magazine you might want to get an ISBN or ISSN number instead).

Yes, our barcodes are legal for use in Ireland (and worldwide). They originally came from UCC (since renamed GS1-US) hence are part of the global system.

To our knowledge, the barcodes we sell are accepted by every retailer in Ireland & the UK. If you are planning to export your product overseas, there are a few retailers that won’t accept our barcodes because they have a specific requirement that you must be a member of GS1 (these stores are Kroger’s and Walmart in the USA, Woolworths in Australia, and Super Retail Group in Australia and New Zealand).

Yes, it will. The barcodes we sell are international codes. They can be used in any country in the world. We have been in business since 2007. We have customers that are successfully using our barcodes in Asia, Europe, America, the Middle East, and the Pacific Islands. /EXPAND]

Yes. Our barcodes come from UCC (now called GS1-US), which is the official barcode body. UCC (the Uniform Code Council) first allocated our barcodes to a company in the USA (before UCC started charging annual membership fees). This company then on-sold a large block of numbers that they didn’t need, and we purchased some of these.

Here is a more detailed explanation: Our barcode numbers were assigned by UCC (now called GS1-US) to manufacturers in the USA in the early 1990s before GS1-US had started charging membership fees. When GS1-US introduced annual membership fees in the early 2000s, these manufacturers refused to pay & took GS1 to Court. The manufacturers succeeded, winning an out-of-court settlement of about $4,000,000 USD. Under the terms of the settlement, these manufacturers owned their barcode numbers & did not have to pay any membership fees to GS1. Some of these manufacturers had large quantities of un-needed barcode numbers, so they chose to sell some of these numbers to other companies. This is where our barcode numbers come from.

We offer a company prefix to customers who buy 10, 100 or 1,000 barcodes at once- the length of the prefix is determined by the number of codes bought. Read more about how this works on our Company Prefix page.

No product (or company) information is contained in a barcode. A barcode is simply a unique sequence of digits (encoded into vertical black bars and spaces). Your barcode will only become connected to your product when it is put into a database or a retailer’s inventory system.

The standard size for an EAN-13 barcode is about 38mm wide, but anything within 80% – 200% of the standard size is okay. The smallest recommended width for an EAN-13 barcode is 30mm. For more information, see the official standards for barcode size.

Our barcodes can be registered in a few databases such as This database feeds into other databases and your barcode will show on a google search if you register information. There is no one central database for barcode numbers. After you receive a barcode number from us, you can begin using it straight away. You do not have to register it first. It is your responsibility to monitor the correct use of your barcode number. In particular, make sure that each barcode number is only assigned to one product. Our company offers an optional barcode registration service (this is not compulsory). If you purchase barcode registration from us, we will register your barcode & product on the major internet databases.

Printing your barcode in black on white is the safest thing to do, however, it is okay to print the barcode in some other colours too. If you are adding colour to the barcode, the background of the barcode needs to be a warm colour (eg. red, yellow, or orange) and the bars needs to be a cool colour (eg. green or blue). You cannot use metallic colours on any part of the barcode. If you print your barcode in colours other than black and white, we recommend that you thoroughly test the barcode to ensure that it scans well before using it. You should not print your barcode in metallic colours.

We will then email your barcode images to you & you can start using them in your book.

Magazines need an ISSN number. You need to get one of these numbers assigned to your publication (please see Magazine Barcodes for info on obtaining an ISSN). Then come back to us and order the barcode images for your number online. We will then email your barcode images to you & you can start using them in your magazine.

A GLN is a globally unique number that is used by some retailers as a location identifier for suppliers. If you require one of these, it can be purchased here.

Both UPC-A Numbers and EAN-13 numbers are common retail barcodes. At the checkout they retrieve the price and other product information. The main difference between them is that UPC-A barcodes are 12 digits and EAN-13 barcodes are 13 digits. Furthermore, the displacement of the numbers below the barcodes differs.

Both versions are designed for international use, and can therefore in theory be used throughout the world, however, UPC-A Barcodes are far more common in the USA, and EAN-13 Barcodes are far more common everywhere else. This means that some retailers may be unfamiliar with one format or have their system set up so that it cannot accept 13 digit or 12 digit numbers. Regardless of this, either format can be used.

As can be seen in the image below, the actual bars of the UPC-A format barcode and the EAN-13 format barcode (with a leading ‘0’) are identical. This means that they will scan in exactly the same way regardless of which country they are in. If a retailer’s system does not allow 13 digit numbers, the leading ‘0’ can be ignored when typing the number into the system and, the barcode will work in the same way as if it were a UPC-A format barcode. Similarly, if 13 digits are required, a ‘0’ can be added to the beginning of the UPC-A barcode to turn it into an EAN-13. Either way round, the barcode will be globally unique and legal for use internationally.


[EXPAND What Country Code (first digits) will your barcode have?“] Our barcodes begin with a ’07’. This means that the barcodes themselves originally come from the USA, however, this says nothing about the origin of the products themselves. Products from any country can use barcodes from the USA and vice versa.
