Check Product Authenticity with Our Barcode Scanner

One of the most valuable uses of our barcode scanner online to check authenticity is verifying whether products are genuine. Counterfeit goods cost businesses and consumers billions annually, but a simple barcode scan can help protect you.

How Authenticity Checking Works:

When you scan a product barcode, our tool instantly decodes the embedded information, including:

• GS1 Country Prefix - Identifies where the product was registered (not necessarily manufactured)
• Manufacturer Code - Unique identifier for the company that produced the item
• Product Code - Specific identifier for the individual product
• Check Digit - Mathematical validation to ensure the barcode is legitimate

By cross-referencing this information with product databases and manufacturer records, you can spot red flags like:

• Barcodes that don't match the claimed country of origin
• Product codes that don't exist in official databases
• Suspiciously low prices for luxury goods with valid-looking barcodes
• Packaging inconsistencies compared to authentic products

While a barcode scan alone can't guarantee 100% authenticity (sophisticated counterfeiters can copy legitimate barcodes), it's an essential first step in verification, especially for high-value purchases.

Comprehensive Barcode Format Support

Our scanner recognizes all major barcode formats used worldwide, making it the most versatile barcode scanner online free tool available:

1D Barcodes (Linear Barcodes)

UPC (Universal Product Code) - The familiar barcodes you see on retail products throughout North America. UPC-A uses 12 digits and is standard for most consumer goods, while UPC-E is a compressed 6-digit version for smaller packages.

EAN (European Article Number) - The global standard for product identification, used on over 90% of retail products worldwide. EAN-13 is the 13-digit international standard, while EAN-8 is used for small products with limited packaging space. Need to create your own? Use our free EAN-13 barcode generator.

Code 128 - A high-density barcode that can encode any ASCII character, making it ideal for logistics, shipping labels, and warehouse management. It's the go-to choice when you need to encode numbers, letters, and special characters. Create your own with our Code 128 barcode generator.

Code 39 - A robust alphanumeric barcode commonly used in automotive, defense, and healthcare industries. While less dense than Code 128, its simplicity makes it reliable for industrial applications.

ITF (Interleaved 2 of 5) - Used primarily on corrugated cardboard boxes in the distribution chain. You'll find these barcodes on shipping cartons and warehouse packaging.

2D Barcodes (Matrix Codes)

QR Codes - The most recognizable 2D barcode, QR codes can store URLs, contact information, WiFi credentials, payment information, and much more. Their error correction capabilities allow them to function even when partially damaged. Generate your own instantly with our free QR code generator.

Data Matrix - Small, square barcodes that can encode large amounts of data in minimal space. Commonly used for marking small electronic components, pharmaceutical products, and manufacturing parts. Perfect for constrained spaces - try our Data Matrix generator.

PDF417 - A stacked linear barcode that stores substantial amounts of data. You'll find these on driver's licenses, boarding passes, and shipping labels where multiple lines of information need encoding. Create them easily with our PDF417 barcode generator.

Aztec Code - Similar to QR codes but more compact, Aztec codes are popular for ticketing applications, including airline boarding passes and event tickets. Generate Aztec codes using our specialized generator tool.
