Yes, however Amazon doesn’t let you change the EAN for a similar product already existing on Amazon. Brand and manufacturer should not be a known brand who may already have an existing EAN. To post under your own brand you have to go through brand registration, which you cannot do with our codes because you need your own prefix. However you can post products under a brand name that has 3-4 letters as algorithms allow it without brand registry. If you are trying to create variations of existing products it will not work if the other variations have different code prefix, you will have to create a new product.

You need one code for each product ‘variation’, such as size and color. For example, 2 t-shirt designs, 5 sizes each and 2 colours each, will require 20 codes (2 * 5 * 2).

Quickly communicate enabled technology and turnkey leadership skills. Uniquely enable accurate supply chains rather than frictionless technology. Globally network focused materials vis-a-vis cost effective manufactured products.

You will receive by email UPC-A (12 digits) codes AND EAN-13 (13 digits) codes, both are variant of the same code. Each code is accompanied by graphics of the corresponding barcode.

Our codes will work for all products but books and pharma, but ok for health products such as protein powders, etc.

Absolutely, our codes will work worldwide, online and in retail.

We don’t need information about your product, price or company, you use the codes to register directly your products with your distributor (e.g. Amazon, CD Baby, supermarkets, grocery stores, etc). They will link the information as well as price to the code for you.

If you sell products online you should only need the numbers, however if you sell through a distributor instead of sending the products directly, you may need to print the barcodes on stickers, which you can do with the images we provide you with your order, or by using our printing service.

Since this item is a digital download all sales are final. If unsure buy one, try it, and if you purchase at least 100 more we’ll reimburse the first one.

Do I need a barcode to sell my greeting cards?
Yes, you must have a unique barcode to sell cards.

It depends on how many styles you have. For example, if you have a birthday card with a car on the front and another with a puppy on the front, that means you need two different barcodes. If you have a birthday card with a car and happy birthday on the front, and another with a car and happy birthday on the front, then you will need two different barcodes. As soon as you change something about your card, it becomes a different product and needs its own barcode number.

You can give the image format of the barcode number to your graphic designer and they can put it directly on the card for you. If you design and print the card yourself, you can put the barcode graphic in EPS or JPEG format directly on the card. We also send you UPC and EAN designs in JPEG format.

No, this is not necessary. You will give this information to the stores where your products will be sold.

Yes. You will need barcodes if you are selling to a retail or online store.

One for each album title. If you change anything about your album, it becomes a different album and needs a different barcode.

You can use an unlimited number of barcodes as long as they are COMPLETELY on the same product. As soon as you change something about your product, it becomes a new product and needs a different barcode number.

We offer you 100% of digital images that are approximately 1.5” wide x 1” tall. If you need to change the size, the width should never drop below 80% or 1.2”, but the height can be reduced as much as you want, but we do not recommend going below 0.25”. Most people stop at 0.5 inches to make sure they have enough lines to be scannable.

UPC Barcode EAN Barcode
It is commonly known as UPC, UPC-12, UPC-A or Universal Product Code. It is commonly known as the European Article Number, renamed as EAN, EAN-13, GTIN-13 or International Article Number.
12 digits long 13 digits long
Currently valid and accepted worldwide
In addition to the list above, the other difference is the format of the number. If you assign a UPC number to a product, you cannot take the same number in EAN format and assign it to a different product. If you do, you have assigned the same barcode number to two different products.


UPC barcode 123456789104 and EAN barcode 0123456789104

You can see that the EAN barcode has the same numbers except that it has a 0 in front of it. The 0 does not change the value of the barcode, but gives it the 13 digits needed to convert the UPC format to the EAN format and is therefore valid and accepted worldwide. 0 also indicates that the barcode number originates from the United States.

You need to correlate your barcode and your product. You do this by listing your product at online retailers or any online listing service, and you can contact the company that created the smartphone app to get listed in the database.

Different products = different variations

Namely, color, size, fragrance, shape, quantity, design, style etc. change it, each of these changes will make it a different product and must have its own barcode number.

The answer to both of these questions is no. GS1 is a company, just like us.

Although UPCs change ownership all the time, the name of the owner of the GS1 prefix does not change in the database, so an unfamiliar company may appear.

The only meaning of the company in the GS1 database is that the code has been verified by GS1. The name in the database is the original prefix owner, not the current UPC owner.How do I get my UPC Codes once I’ve paid for them?

They are the company where all barcode numbers originated from. After a civil suit settled, they changed their name to GS1 in 2005.
