Frequently Asked Questions

The codes themselves are not generated by us. They are originally issued by GS1, then sold to companies that do not use them, and we acquire them for resale. Please note, you will not receive a unique company prefix, but these codes are fully valid and accepted for selling your products.

Our barcodes are suitable for all types of products except books and pharmaceuticals. They are fine to use with health products, including items such as protein powders.

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

The prefix is simply an indication of which country the barcode originates in but is not at all a condition to sell in a country. GS1 explains "since GS1 member companies can manufacture products anywhere in the world, GS1 prefixes do not identify the country of origin for a given product." We have people using our codes with US prefix to sell in the UK in Waitrose and Debenhams for example, or products "made in France" in France. If someone say they will sell you codes with an UK prefix it will not be legit, as only US companies were once allowed to resell their codes. See also here and here.

You will need a separate code for each product variation (for example size, colour, or design). For instance, if you have 2 t-shirt designs, each available in 5 sizes and 2 colours, you will require 20 codes (2 × 5 × 2).

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.

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.

Yes. Many of our customers list on Amazon with our UPC and EAN codes. Most problems come from the brand field or Amazon's brand-approval rules rather than the code, and this page covers the common ones. For some brands and categories Amazon can require a GS1 company prefix in your own name; our codes do not provide one.

Because the code is resold. GS1 keeps the name of the company each prefix was first issued to, and that does not change when codes are resold. The code is still valid and used only by you; your transfer certificate and invoice show that you bought it.

No. A GTIN exemption lets you list without a barcode, mainly for unbranded, handmade or private-label goods. With our UPC or EAN codes you list with those instead. The exemption is only a fallback if Amazon will not accept a resold code for your brand.

Our Amazon guide explains each error (8572, 5665, 5461, 8541, 8542 and more): what it means, what to try first, a ready-made message for Seller Support and the documents to attach. It also sets out our works-on-Amazon guarantee.

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.
