Frequently Asked Questions
What is a Barcode Generator?
A Barcode Generator is a tool that converts numerical or alphanumeric text data into a visual barcode representation, allowing it to be scanned by optical readers or smartphones.
What types of barcodes can I generate?
This tool supports various formats including UPC-A (retail), EAN-13 (international), Code 128 (logistics/inventory), QR Code (2D data), and ITF-14.
Can I use these barcodes for retail products?
Yes, formats like UPC-A and EAN-13 are standard for global retail. However, for official resale, you must ensure the numbers assigned to you are registered with GS1.
What is the difference between 1D and 2D barcodes?
1D barcodes (like Code 128) represent data by varying the width and spacing of parallel lines. 2D barcodes (like QR Codes) use patterns of squares, dots, and hexagons to store data both horizontally and vertically.
Can I customize the look of the barcode?
Yes, you can often adjust parameters such as the bar width (height), foreground and background colors, and whether the human-readable text is displayed below the code.
Why is the generated barcode not scanning?
This usually happens due to low resolution during printing, insufficient quiet zone (white space) around the barcode, or incorrect color contrast (e.g., red bars on a white background).
