Frequently Asked Questions
What is a barcode?
＋
A barcode is a machine-readable representation of data in a visual, scannable format. It consists of parallel lines (or patterns) of varying widths that encode information like product IDs, prices, or inventory numbers.
Which barcode format should I use?
＋
Use CODE128 for general alphanumeric data, EAN13 for retail products in Europe, UPC for North American retail, CODE39 for industrial or logistics labels, and ITF14 for shipping/carton barcodes.
Can I download the barcode for free?
＋
Yes. All barcodes generated on UtilityX are completely free to download in both PNG and SVG formats, with no watermarks or account required.
What is the difference between PNG and SVG download?
＋
PNG is a raster image suitable for printing and most use cases. SVG is a vector format that scales to any size without losing quality, ideal for professional printing or design tools.
Does EAN13 require a check digit?
＋
EAN13 requires exactly 13 digits including a check digit at the end. The generator validates the format automatically before rendering.
Can I use these barcodes commercially?
＋
Yes, you can use the generated barcodes for commercial purposes. However, if you need GS1-registered barcodes (e.g., for selling in major retailers), you must obtain an official GS1 company prefix.
