If you’re launching a product online or preparing to sell through retail stores, you’ll quickly encounter two common barcode formats: EAN barcodes and UPC barcodes.
Many business owners, Amazon sellers, Shopify merchants, and product manufacturers ask the same question:
What’s the difference between EAN and UPC barcodes, and which one should I use?
The good news is that both barcode types serve the same primary purpose—identifying products—but there are some important differences that can affect where and how you sell your products.
In this guide, we’ll explain everything you need to know about EAN and UPC barcodes, helping you choose the right barcode for your business.
What Is a Barcode?
A barcode is a machine-readable representation of a unique product number. Retailers, warehouses, online marketplaces, and point-of-sale systems use barcodes to identify products quickly and accurately.
The barcode itself is simply a visual representation of a product identifier known as a GTIN (Global Trade Item Number).
EAN and UPC are both types of GTINs used around the world.
What Is an EAN Barcode?
EAN stands for European Article Number.
An EAN barcode contains 13 digits and is the most widely used retail barcode format globally.
EAN barcodes are commonly used in:
- United Kingdom
- Europe
- Australia
- New Zealand
- Asia
- Africa
- Most international retail markets
Example EAN:
5012345678901
EAN barcodes are accepted by most major retailers, eCommerce platforms, and inventory systems worldwide.
What Is a UPC Barcode?
UPC stands for Universal Product Code.
A UPC barcode contains 12 digits and is traditionally used in:
- United States
- Canada
- North American retail markets
Example UPC:
012345678905
UPC barcodes perform the same function as EAN barcodes but use a slightly shorter numbering format.
EAN vs UPC: The Key Differences
| Feature | EAN Barcode | UPC Barcode |
|---|---|---|
| Number of Digits | 13 | 12 |
| Primary Region | Global | USA & Canada |
| Retail Acceptance | Worldwide | North America |
| GTIN Type | GTIN-13 | GTIN-12 |
| Amazon Compatibility | Yes | Yes |
| Shopify Compatibility | Yes | Yes |
| Retail Store Compatibility | Yes | Yes |
For most businesses, the practical difference is simply geographic preference rather than functionality.
Are EAN and UPC Barcodes Compatible?
Yes.
Modern retail systems and online marketplaces generally recognise both barcode formats.
In fact, an EAN barcode can often be created by adding a leading zero to a UPC barcode.
This means businesses selling internationally can often use either format depending on their target market.
Which Barcode Does Amazon Require?
Amazon accepts both EAN and UPC barcodes for most product listings.
The specific barcode format is usually less important than ensuring the barcode number is unique and correctly assigned to your product.
Many UK and European Amazon sellers prefer EAN barcodes because they align with international retail standards.
Which Barcode Is Best for Shopify?
Shopify supports both EAN and UPC barcode formats.
Store owners can use either barcode type for:
- Inventory tracking
- Product management
- Order fulfilment
- Retail integrations
If you plan to sell internationally, EAN barcodes are often the preferred choice due to their wider global recognition.
Should You Choose EAN or UPC?
Choose EAN Barcodes If:
- You sell in the UK
- You sell throughout Europe
- You plan to expand internationally
- You want the globally recognised standard
Choose UPC Barcodes If:
- Your primary market is the United States
- You only sell within North America
- Your retail partners specifically request UPC numbers
For many modern businesses, EAN barcodes offer the greatest flexibility because they are recognised worldwide.
Why Barcodes Matter for Online Sellers
Whether you’re selling through Amazon, eBay, Shopify, Etsy, Walmart Marketplace, or traditional retail stores, barcodes help:
- Identify products uniquely
- Improve inventory accuracy
- Reduce fulfilment errors
- Simplify stock management
- Support retail distribution
- Enable marketplace listings
As your business grows, barcode management becomes increasingly important for efficient operations.
Frequently Asked Questions
Is EAN better than UPC?
Neither barcode is inherently better. EAN is simply more widely used internationally, while UPC remains common in North America.
Can I convert a UPC barcode to an EAN barcode?
In many cases, an EAN version can be created by adding a leading zero to the UPC number.
Do I need a barcode to sell on Amazon?
Most products require a valid product identifier such as an EAN, UPC, or GTIN, although some categories may qualify for exemptions.
Which barcode is best for international sales?
EAN barcodes are generally preferred for international retail and eCommerce because they are recognised globally.
Final Thoughts
When comparing EAN vs UPC barcodes, the differences are relatively small. Both formats identify products, support retail sales, and work with major online marketplaces.
For businesses selling in the UK, Europe, or internationally, EAN barcodes are typically the preferred option due to their worldwide acceptance. Businesses focused exclusively on North America may choose UPC barcodes instead.
The most important factor is ensuring your products have unique, valid barcode numbers that support future growth across online and retail sales channels.
