Frequently Asked Questions
What is the difference between barcode formats?
CODE128 is versatile and supports all ASCII characters. EAN13/8 are international product codes (13 or 8 digits). UPC is used for retail products in North America (12 digits). CODE39 supports letters, numbers, and some symbols.
Which barcode format should I use?
Use CODE128 for general purposes or if you need letters and numbers. Use EAN or UPC for retail products (check with your retailer for specific requirements). Use CODE39 if you need a simple alphanumeric barcode.
Why am I getting an error message?
Each barcode format has specific requirements. EAN13 needs 12-13 digits, EAN8 needs 7-8 digits, UPC needs 11-12 digits. CODE39 only accepts uppercase letters, numbers, and certain symbols. CODE128 accepts any ASCII character.
Can I use these barcodes for commercial products?
You can generate the barcode image, but for retail products (EAN/UPC), you need to purchase a legitimate company prefix and product code from GS1 or an authorized reseller. This tool creates the visual barcode from numbers you provide.
What's the difference between PNG and SVG downloads?
PNG is a raster image format suitable for web use and printing at a specific size. SVG is a vector format that scales infinitely without quality loss, ideal for professional printing or when you need flexibility in sizing.
Will my barcode work with standard scanners?
Yes! The barcodes generated follow industry standards and will work with standard barcode scanners. Ensure you use appropriate size and resolution for your application (especially for printing).
Should I show or hide the text below the barcode?
Showing text (default) makes it easier for humans to manually enter the code if scanning fails. Hiding text creates a cleaner look and is useful when the barcode value isn't meant for manual entry.
How large should my barcode be for printing?
For reliable scanning, print barcodes at least 1 inch (2.5cm) wide. Larger is better for outdoor use or scanning from a distance. Use SVG format for printing to ensure crisp edges at any size.
