EAN Number Search: How to Look Up European Barcodes Online

EAN (European Article Number) is the international barcode standard used on virtually every product sold outside North America. If you're working with global e-commerce, understanding EAN number search is essential.

What Is an EAN Number?

An EAN is a 13-digit barcode (EAN-13) that uniquely identifies a product worldwide. It's the international counterpart to the 12-digit UPC used in North America.

EAN Structure

EAN-13: 0 012345 678905
        │ │      │
        │ │      └── Check digit
        │ └── Product code (assigned by manufacturer)
        └── Country/region prefix (assigned by GS1)

Country Prefixes

Note: The prefix indicates where the barcode was **registered**, not where the product was manufactured.

How to Search Products by EAN

Method 1: Free Online Lookup

Visit EcomSource.ai and enter any EAN-13 number in the search bar. You'll get instant results including:

• Product name and brand
• Matching UPC and ASIN codes
• Product images and specifications
• Category information

Method 2: API Lookup

ean = "4006381333931" # German product response = requests.post( "https://api.ecomsource.ai/api/v1/search/product", json={"identifier": ean, "identifierType": ""}, headers={ "X-Access-Key": "your_access_key", "X-Secret-Key": "your_secret_key", }, headers={"X-Access-Key": "your_access_key", "X-Secret-Key": "your_secret_key"} )

product = response.json() print(f"Product: {product['title']}") print(f"UPC: {product['upc']}") print(f"ASIN: {product['asin']}") ```

Method 3: Chrome Extension

Install the EcomSource Chrome Extension and scan EAN barcodes directly from any webpage or Amazon listing.

EAN to UPC Conversion

Converting between EAN-13 and UPC-12 is straightforward:

• EAN to UPC: Remove the leading zero (only works for EANs starting with "0")
• UPC to EAN: Add a leading "0"

def ean_to_upc(ean: str) -> str:
    """Convert EAN-13 to UPC-12 (US barcodes only)."""
    if len(ean) == 13 and ean.startswith("0"):
        return ean[1:]

def upc_to_ean(upc: str) -> str: """Convert UPC-12 to EAN-13.""" if len(upc) == 12: return "0" + upc return None ```

Important: Only EANs starting with "0" have equivalent UPCs. A German EAN starting with "400" has no UPC equivalent.

EAN Search for International Sellers

Cross-Border Selling

If you sell products internationally, you need EAN codes for non-US marketplaces. EcomSource maps products across all identifier types, so you can:

1. 1Start with a US UPC code
2. 2Get the corresponding EAN-13
3. 3Use that EAN to list on Amazon EU, Japan, or Australia
