Free UPC & EAN Barcode Scanner

Read the numbers on any retail product barcode. This scanner decodes UPC-A, UPC-E, EAN-13 and EAN-8 codes using your camera or an image upload, entirely in your browser.

What Are UPC and EAN Barcodes?

UPC (Universal Product Code) and EAN (European or International Article Number) are standard point-of-sale barcodes found on packaged retail goods across the globe.

UPC-A features 12 numerical digits and is the primary barcode format on consumer goods in the United States and Canada. EAN-13 features 13 numerical digits and is standard on retail products, books, and groceries worldwide.

In international database standards, a 12-digit UPC-A is identical to an EAN-13 with a leading zero added. Both symbologies encode numbers using alternating black and white bars with specific module widths.

UPC-E (6 digits) and EAN-8 (8 digits) are zero-suppressed, compact versions engineered for small packages such as chewing gum, cosmetics, or pharmaceuticals where full-sized 12 or 13-digit labels will not fit.

How to Scan a UPC or EAN Code

You can scan retail barcodes using your smartphone camera, computer webcam, or an uploaded photo:

Scan with Camera

Click "Open Camera", allow browser camera permissions, and point the lens at the retail product. Align the red guidance line across the full width of the vertical bars, and click "Capture" to read the numbers.

Scan from an Image

Switch to the "Upload Image" tab and select or drop a clear photo of the product package barcode. The scanner decodes the numerical digits immediately without uploading the picture to any server.

Understanding the Number

Retail barcodes have a standardized structure designed for global logistics and automated checkout accuracy.

The final digit on the far right is a mathematical check digit. It is calculated from the preceding digits using a modulo-10 algorithm. Scanners use this check digit to verify that every bar was read accurately, eliminating transcription typos.

The leading digits identify the country licensing authority and the manufacturer prefix assigned by GS1. The middle digits represent the specific item reference code chosen by the manufacturer to identify that particular size, color, or formulation.

What This Scanner Does Not Do

This scanner decodes the exact numerical sequence printed within the barcode stripes. It does not look up product names, commercial store prices, or consumer reviews from retail inventory databases.

Keeping the tool focused strictly on optical barcode decoding ensures 100% privacy, zero tracking, and immediate client-side performance without external database dependencies. For general scanning needs, use our free online barcode scanner.

Frequently Asked Questions

1. What is the difference between UPC and EAN?

UPC-A codes have 12 digits and are standard on retail packaging in North America, while EAN-13 codes have 13 digits and are used globally. A 12-digit UPC-A is compatible with EAN systems by adding a leading zero.

2. Can I scan a UPC code with my phone camera?

Yes. Tap "Open Camera", grant browser camera permissions, and align the product barcode in the viewfinder to capture and decode the digits.

3. Does it show product details or prices?

No. This tool decodes the raw 12-digit or 13-digit barcode number. It does not look up product descriptions, retail pricing, or store reviews, which guarantees complete privacy.

4. Why is the code 12 digits on some products and 13 on others?

Products packaged for the North American market use 12-digit UPC-A codes, while products manufactured or distributed internationally use 13-digit EAN-13 codes.
