What is UPC Code? Why to use UPC Code for Amazon or any other marketplace?

If you are a seller on Amazon, then you should pay attention to this post. There are indications that Amazon might soon start enforcing stricter rules on UPCs used for product listings. Let’s break down what this means and how it might affect you.

First, let’s understand one the about UPC Codes: it is used as a unique ID for every single product listed on Amazon. They help track and manage inventory. In simpler words, it’s like giving each item a specific number to identify with.

Originally, UPCs were the standard format. But as demand for UPCs increases in other countries like Europe, Asia, and Australia, an issue comes out: how to differentiate the products originating from different locations. That’s when GS1 came into the picture. They added country codes to the beginning of the standard UPC, allowing for better distinction across regions.

Now, the key point: we believe that Amazon might soon check if the UPCs used by sellers on their platform match the official GS1 database. This could lead to listing removal for sellers using incorrect codes.

Why Buy UPCs for Amazon?

Amazon requires every seller to register a GTIN with each product listing available on their marketplace. With that being said, sellers can either invest in legitimate Amazon UPCs directly from GS1 or go through a reseller. Various UPC and EAN resellers out there will try to sell replicated UPCs to satisfy Amazon’s UPC needs. Many sellers purchase their UPCs for Amazon from third-party websites due to their cheaper prices; however, using resold Amazon UPCs will cause more harm than good in the long run.

A typical process of how to get a UPC (code) number having 12 digits is as follows:

  1. License a unique Company Prefix from your local GS1 office.
  2. Assign product numbers to unique products making your equal 11 digits.
  3. Using a check digit calculator with your 11-digit number, generate your check digit.

UPC Sizing Requirements

UPC sizes are referred to as magnifications or magnification factors. The nominal size of a UPC is 100% magnification factor or 1.469 inches wide (from the far left-hand side number to the far right-hand side number) by 1.02 inches tall (from the top of the barcode to the bottom of the human-readable numbers). The minimum size of a UPC is 80% magnification factor (80% of the nominal size) and the maximum size of a UPC is 200% magnification factor (200% of the nominal size).

UPC Coupon Codes

The data bar and GS1-128 coupons currently contain a UPC. However, the new GS-1 Data Bar strips the UPC from the coupon. Most of the main retailers will not accept their numbers and many online websites are preying on unsuspecting new companies. Quite simply, buying the “UPC Codes” from any organizations other than GS1 puts you at risk of acceptance by retailers. There may be smaller retailers and online marketplaces that do not require a unique GS1 Company Prefix.

Acquiring a barcode for your product is an easy four-step process:

Step 1: Apply for a GS1 Company Prefix.

Step 2: Assign a unique product number

Step 3: Determine how your product will display the barcode.

Step 4: Order your barcodes.

At the end of this simple tutorial, you will be provided information on obtaining a UPC barcode with a unique GS1 Company prefix assigned to your company.

The Usefulness of Using GS1 Barcode for Amazon

As an Amazon seller, one should already be familiar with UPCs and what they entail. There is only one legitimate producer of Amazon UPC codes that exists globally, GS1 (Global Standard 1) has set the global standard for supplying chain barcoding. GS1 issues every product supplier with GTINs (Global Trade Item Number). There are many sites to buy cheap UPC codes.

What is GS1?

GS1 is a not-for-profit organization that develops and maintains Global standards for business communications. The best known of these standards is the barcode, a symbol printed on products that can be scanned electronically. GS1 barcodes are scanned more than six billion times every day.

GS1 has 112 local members organizations and 1.5 million user companies. GS1 standards are designed to improve the efficiency, safety, and visibility of supply chains across physical and digital channels in 25 sectors. They form a business language that identifies and captures and also shares key information about products, locations, assets, and more. So, one must know where to buy UPC code.

History of GS1

In 1969, the retail industry in the US was searching for a way to speed up the check-out process in shops. The Ad Hoc Committee for a uniform Grocery Product Identification Code was established to find a solution.

In 1973, the Universal Product Code (UPC) was selected by this group as the first single standard for unique product identification, and in 1974, the Uniform Code Council (UCC) was founded to administer the standard. On 26th June 1974, a pack of Wrigley’s chewing gum became the first ever product with a barcode to be scanned in a shop.

In 1976, the original 12 digit code was expanded to 13 digits, which opened the doors for the identification system to be used outside the U.S. In 1977, the European Article Numbering Association (EAN) was established in Brussels and with founding members from 12 countries.

In 1990, EAN and UCC signed a global cooperation agreement and expanded overall presence to 45 countries. In 1999, EAN and UCC launched the Auto-ID Centre to develop Electronic Product Code (EPC) enabling GS1 standards to be used for RFID.

In 2004, EAN and UCC launched the Global Data Synchronisation Network (GDSN), a global, internet-based initiative that enables trading partners to efficiently exchange product master data.

In 2005, the organization was present in over 90 countries which started to use the name GS1 on a worldwide basis. Whilst “GS1” is not an acronym it refers to the organization offering one global system of standards.
