A Summary Of UPC Barcodes

What are UPC barcodes?

A Universal Product Code (UPC) is a 12-digit numeric barcode that serves as a unique identifier for products and their manufacturers. When scanned, a UPC instantly populates product information, facilitating fast checkouts and accurate inventory tracking. UPCs are standardized by the Global Standards Organization (GS1) and are often technically called “UPC-A barcodes.” You can also find UPCs under “EAN” but with 13 digits, strictly following the European standard.

The GS1 system offers varied globally recognized product codes, including UPCs

3 Key Components in UPCs

Every 12-digit UPC is comprised of three distinct sections, each encoding vital information:?

1. UPC company prefix:?The initial 6 digits represent a unique manufacturer identification number assigned by GS1. This prefix identifies the company that produced the product.

2. Item number:?The subsequent 5 digits are the item number, which is unique to a specific product variant. For instance, a coffee brand's 12-oz bag of "Dark Roast" would have a different item number than their 12-oz bag of "Light Roast”. Similarly, a 24-oz bag of "Dark Roast" would carry a distinct item number compared to its 12-oz counterpart.

3. Check digit:?The final digit in the UPC is the check digit. This digit is calculated using a complex algorithm based on the preceding 11 digits and is known as a validation tool. Once the check digit is incorrect, the UPC will not scan properly, preventing mistakes.?

When to use UPC barcodes??

Sellers can use? free UPC barcode generators?to create tailored UPCs for various purposes. Here’s when you will find these barcodes most useful to streamline your operational process:??

Sell on eCommerce platforms and marketplaces

Most eCommerce platforms (e.g., Shopify, Magento, WooCommerce) and online marketplaces (e.g., Amazon, eBay,? Google Shopping) require your products to have unique UPCs for listing.? This is essential to maintain product authenticity and categorization across their vast catalogs.

Start in-person retail and wholesale operations

If you plan to sell your products in physical retail stores or through wholesale distributors, UPCs are virtually mandatory. They help you enable quick and accurate scanning at the point of sale, making? UPC-A free barcode generators?a perfect fit with? Shopify POS apps?or Shopify POS Go.?

Streamline your supply chain?

UPCs allow for precise tracking of product movement from the warehouse to customers. As a result, sellers can easily monitor stock levels, identify fast-moving items, and control reordering. It is known as one of the most widely used? Shopify inventory management?strategies nowadays.??

Moreover, ensuring that the correct products are picked and packed for each order can minimize errors and improve customer satisfaction, which further optimizes order fulfillment. Once inventory management and order fulfillment are efficient, they contribute to a successful supply chain. From that, Shopify sellers can easily boost their overall operational performance.???

What is the difference between SKU and UPC?

While both SKUs (Stock Keeping Units) and UPCs are used for product identification, they serve fundamentally different purposes and are created in distinct forms. Therefore, you need to understand their differences to ensure effective inventory management in your Shopify store. Below is a quick comparison table between SKU vs. UPC so that you can easily review it shortly:?

Feature | UPC (Universal Product Code) | SKU (Stock Keeping Unit)
Purpose | External tracking | Internal tracking
Creator | Assigned by GS1 | Assigned by individual businesses
Format | Numeric code (12 characters) | Alphanumeric code (8-12 characters)
Uniqueness | Globally unique for each product type/variant. | Unique within a single business's inventory system.
Portability | Universal, recognized by all retailers and systems worldwide. | Not universal; specific to one company's system.
Example | 012345678905 (for a particular brand of shampoo) | SHAM-CITRUS-8OZ (for citrus-scented shampoo, 8oz bottle)

What Are UPC Barcode Generators?

These generators simplify the process of creating UPCs (and other barcode types) without the need for complex installation or specialized knowledge.
