What is Product Barcode Generator Tool?
A product barcode generator tool creates machine-readable codes that represent product information. These barcodes are essential for retail operations, inventory management, and supply chain tracking. They enable quick product identification, accurate pricing, and efficient checkout processes. Modern barcodes (like EAN-13/UPC-A) contain 12-13 digits encoding country code, manufacturer ID, product number, and checksum. This tool helps businesses create compliant barcodes for product labeling, e-commerce listings, and warehouse management without specialized software.
How to Use
1. Enter 12-digit number in the input field (EAN-13 format)
2. Click "Generate Barcode"
3. Verify the generated barcode
4. Click "Download Barcode" to save as PNG
5. Use "Clear" to reset. Note: EAN-13 requires 12 input digits (automatically calculates checksum). For other formats, ensure proper digit count. The tool validates input length and numeric format. Generated barcodes can be printed or embedded in product packaging and digital listings.
Barcode Formula
EAN-13 barcode uses modulo-10 checksum calculation:
1. Sum even-position digits (excluding check digit) × 3
2. Sum odd-position digits
3. Total = (Step1 + Step2)
4. Checksum = (10 - (Total % 10)) % 10
Example: For 123456789012
(2+4+6+8+0+2)×3 + (1+3+5+7+9+1) = 66 + 26 = 92
Checksum = (10 - 92%10) %10 = 8
Full code: 1234567890128
What is a product barcode generator tool?
A product barcode generator tool is software that creates scannable barcodes for product identification. It converts numeric product codes into machine-readable patterns following international standards like EAN-13 or UPC. Essential for retailers and manufacturers, it automates barcode creation for labeling, inventory tracking, and point-of-sale systems. The tool calculates checksums, ensures format compliance, and provides downloadable images for printing or digital use.
Is the generated barcode scanner-readable?
Yes, barcodes generated using this tool comply with EAN-13 standards and are fully scanner-compatible. They include proper checksum digits, correct bar widths, and quiet zones. Tested with retail scanners and smartphone apps, these barcodes meet ISO specifications for commercial use. Ensure proper printing resolution (minimum 300 DPI) and size (38mm wide × 25mm tall) for optimal scanning.
Can I use these barcodes commercially?
Generated barcodes are technically valid, but commercial use requires GS1 company prefix registration. This tool helps create format-compliant barcodes, but you must obtain legitimate GTIN numbers from GS1 for retail products. Unregistered barcodes may conflict with existing products. Use unregistered codes only for internal inventory management purposes.
