Frequently Asked Questions

It depends on the intended use. We recommend EAN-13 (International) or UPC-A (North America) for general merchandise, Code128 for logistics/inventory management, and Code39 for industrial use. DataMatrix, a 2D barcode, is suitable for small parts or medical devices.

Yes, check digits are automatically calculated for retail barcodes such as EAN-13 or UPC-A. When you enter 12 digits (EAN-13) or 11 digits (UPC-A), the last check digit is automatically added.

Yes, since it is created to standard specifications, it can be scanned normally with a regular barcode scanner. However, please be careful as the recognition rate may decrease if you print in too small a size or if the contrast between the bar color and background color is weak.

You can create up to 100 barcodes at once by uploading the CSV file in the Batch tab or by entering the data directly. Generated barcodes can be downloaded in bulk as a ZIP file or exported to CSV.

As long as there is sufficient contrast between the bar color and the background color, changing the color will not cause any problems in scanning. A combination of a dark bar color and a light background color is generally recommended; red-based bar colors may be difficult to recognize on some red laser scanners.

Tips & Best Practices

  • If you download the printable barcode in PDF format, it will be clear even when enlarged because it is a vector graphic.
  • A quiet zone of at least 2 mm must be secured around the barcode to increase the scanner recognition rate.
  • Frames and captions help you create ready-to-use designs for product labels and price tags.
  • Quickly try out different designs by instantly inverting bar and background colors with Negative Mode.
  • When generating in bulk, leave the CSV file's type column empty to apply the currently selected barcode type to every row.
