Frequently Asked Questions

CODE128: A high-density linear barcode that can encode all 128 ASCII characters. It's versatile and used in various applications.

EAN-13: European Article Number, used worldwide on retail products. It encodes 13 digits (12 + a check digit).

UPC: Universal Product Code, primarily used in the US and Canada for retail. Encodes 12 digits (11 + a check digit).

CODE39: An older but reliable barcode that can encode uppercase letters, numbers, and some special characters.

The best barcode format depends on your specific application:

  • For retail products: Use EAN-13 (international) or UPC (US/Canada)
  • For internal tracking systems: CODE128 or CODE39 are typically used
  • If you need to encode letters and numbers: CODE128 provides the best density
  • For simple numeric data: EAN-13 or UPC are standard for retail

Yes! Barcodes generated by this tool follow international standards and can be scanned by:

  • Smartphone barcode scanner apps
  • Professional barcode scanners
  • Point-of-sale systems

For best results when scanning with a phone, use the PNG download option and ensure adequate print quality if you're printing the barcode.

The optimal size depends on your scanner and application, but general guidelines are:

  • Minimum height: 15mm (0.6 inches) for retail barcodes
  • Quiet zone (empty space around barcode): At least 10 times the width of the narrowest bar
  • Width: Depends on the amount of data, but typically 25-50mm (1-2 inches) for retail

Our generator sets reasonable defaults, but you can adjust width and height as needed for your specific application.

PNG: Best for general use, websites, documents, and printing at specific sizes. Good for most applications.

SVG: Vector format that can be scaled to any size without losing quality. Ideal for design work, large format printing, or when you need to edit the barcode in vector design software.

If you're unsure, PNG is usually the safest choice for most applications.
