Below you will find a list of questions that will answer the most common questions about UPC codes and their use. Please fully read through this page and contact us if you have any other questions.

You can purchase UPC codes directly on our site at kingbarcodes.com. All of our codes come from the GS1 with no renewal or hidden fees, and are delivered instantly at checkout. They work with all vendors including Amazon, Google Shopping, iTunes, eBay, and more!
We sell codes starting at $5 per code, with bulk discounts available. UPC code prices vary on the internet, but we’re the cheapest legitimate seller online. Be careful of companies selling cheaper codes online as there are a lot of fake codes out there. The GS1 is the most expensive place because when purchasing directly from the GS1, you are required to purchase a prefix. However, owning a prefix is not a requirement and the GS1 doesn’t store any product information. As a result, you can buy codes for a fraction of the cost as the GS1 that work fine for all your needs. All of our codes come from the GS1.

Simply go to our UPC page, select the quantity you want, and proceed to checkout.  Your codes will be delivered within 1 minute after you send your payment.  All of our codes work on Amazon.

If you want to sell a product, in most cases, a UPC barcode is required.  We issue the UPC to your company and then you can register your product information with the vendor(s) that you sell at.  On Amazon, we wrote a guide on how to use UPC codes on Amazon here.

Simply go to our UPC page, select the quantity you want, and proceed to checkout.  Your codes will be delivered within 1 minute after you send your payment.  All of our codes work on Amazon.

Every order comes with a .csv file with your UPC code(s) that can be used right away, along with a .zip file with the barcode(s) associated with those codes.  The barcodes come in the following formats: .TIFF, .JPG, .PNG, and .PDF.  If you need any other formats, we’re glad to help provide them to you. A certificate and/or invoice can be provided, by request.

One code costs $5, but the more you buy, the cheaper each code is.  For example, if you buy 100 codes, the cost per code is only $0.45.  Please see our Buy UPC Codes page for full pricing options.

A barcode is simply a visual representation of a UPC/EAN code.  We send barcodes by default with all orders, though if you need specific sizes, please visit our Barcodes page where you can generate them as needed with your UPCs.

A UPC is a universal product code which is used to manage inventory, assign products to codes in stock, prevent duplication of products in a catalog. 

Yes, our codes still work, just as they have for 15+ years.  Some people suggest that Amazon won’t accept 3rd party codes, but this is not true.  They simply want GS1 verified codes, and not “air codes” that don’t verify with the GS1.  Our codes verify with the GS1 and are accepted on all major platforms and services, including Amazon.

If you purchased a UPC code from us, it will always be 12 or 13 digits. However, depending on how you’re viewing the codes, any 0 at the beginning may be truncated.  Simply add a leading 0 to the code and it will resolve the problem.

If your code is showing in the csv spreadsheet as 1.234E+12 or something other than a 12 or 13 digit number, you simply need to reformat the cell display in your settings.  

With each order we send you 2 files, 1 with your codes, and 1 with your barcodes. However, with the UPC code(s), you can easily generate barcodes to your own specifications if the ones we send aren’t the correct format, size, etc. 

Simply add a leading 0 to the UPC code you bought and this will resolve the issue.

All of our codes work at Walmart.  Simply order your codes as usual and create your listings on Walmart.  It’s also best practice to create your listings prior to barcoding your products.  In some cases, Walmart may require you rent from the GS1 directly, in which case we’re glad to help you with that.

Yes, all of our UPC codes are guaranteed to never been previously issued/used and will work instantly on Amazon with no problems.

The GS1 prefix owner name doesn’t change in the database even though UPCs do change ownership all the time, hence why an unfamiliar company may show up.

All that company means in the GS1 database is that the code is GS1 verified.  The name in the database is the original prefix owner, not the current UPC owner.  We own many prefixes (UCC – pre 2002) which we can issue codes from. Your code will work fine on Amazon/Google/iTunes, etc. without issue, and we offer a money back guarantee.  You can read about the UCC Settlement Agreement.

Your UPC Codes will work everywhere online and at most retails, unless they require that you purchase your own company prefix from GS1-US.  In that case, we recommend that purchase your own GS1-US company prefix.

If you’re selling your book through a retail outlet, the retailer will generally require that you obtain an ISBN. The ISBN is a 13 digit number that properly identifies the book title and the publisher’s contact information. We recommend that you check your store’s requirements on UPC and ISBN codes before purchasing from us. Sometimes you can get away with just using a UPC code and then you can purchase the UPC codes from us. However, we do not offer ISBN’s at this time.

Most magazines usually require special bar codes with 5-digit BIPAD numbers that are encoded in them. However, some retailers accept regular UPC or EAN codes. We recommend checking into your retailer first in advance to find out their specific requirements. If they don’t require a BIPAD number, then you can purchase UPC codes through us to put on your magazine.

Until you upload your product to Amazon, Google Merchant Center, or a database that your specific smartphone scanner application is using, it will pull directly from GS1’s database. This information is outdated and doesn’t record the current owner of that specific UPC/EAN number.
