EAN-13: The Global Standard for Product Identification

The EAN-13 (International Article Number) is the most recognized barcode symbology in the world. Used primarily in retail, it allows for the unique identification of products at the point of sale (POS) globally.

1. Understanding the 13-Digit Structure

Every EAN-13 barcode is composed of four distinct sections that provide specific information about the product and its origin:

GS1 Prefix (First 3 digits): Identifies the GS1 Member Organization where the manufacturer is registered (e.g., 869 for Turkey, 000-019 for USA).
Manufacturer Code: A unique code assigned to the company by GS1.
Product Code: Assigned by the manufacturer to identify a specific item.
Check Digit: The final digit, calculated using a mathematical formula to ensure the barcode was scanned correctly.

            Pro Tip: EAN-13 barcodes are mathematically compatible with North American UPC-A codes. A 13-digit EAN-13 is essentially a UPC-A with a leading zero.
          

2. EAN-13 for Amazon and E-Commerce

If you are planning to sell on Amazon, eBay, or Walmart, a valid EAN-13 (or UPC) is mandatory. Amazon verifies your barcode against the GS1 database to ensure authenticity. Using unauthorized or "recycled" barcodes can lead to listing suspension.

3. Technical Printing Requirements

To ensure 100% scannability, EAN-13 barcodes must follow specific dimensions:

Nominal Size: 37.29mm wide x 25.93mm high.
Quiet Zones: Mandatory blank spaces on the left and right sides of the bars. Without these, the scanner cannot differentiate the code from the packaging design.
Color Contrast: High contrast is essential. Black bars on a white background is the industry gold standard.

4. Why Use SVG for EAN-13?

When generating your barcode on Qrivio, we recommend the SVG (Scalable Vector Graphics) format. Unlike PNG, SVG files do not pixelate when resized. This ensures your barcode lines remain perfectly sharp, which is critical for the laser precision of retail scanners.
