Frequently Asked Questions (FAQ)

What is a Barcode?

A barcode is a machine-readable representation of data, typically used to identify products, track inventory, or manage logistics. Barcodes are scanned optically using devices like barcode scanners or smartphone cameras.

What are the supported barcode types?

Our generator supports the following barcode types:

  • Code 128: Alphanumeric, high-density, used in shipping and logistics.
  • EAN-13: 13-digit barcode for retail products worldwide.
  • UPC-A: 12-digit barcode for retail in North America.
  • Code 39: Alphanumeric, used in inventory and industrial applications.

What data can I encode in a barcode?

The data depends on the barcode type:

  • Code 128: Alphanumeric characters (letters, numbers, symbols).
  • EAN-13: Exactly 13 digits (12 + checksum).
  • UPC-A: Exactly 12 digits (11 + checksum).
  • Code 39: Letters (A-Z), numbers (0-9), and some symbols (-, ., $, /, +, %, space).

Are there input restrictions?

Yes, some barcode types have specific requirements:

  • EAN-13 requires exactly 12 digits (the 13th is a checksum calculated automatically).
  • UPC-A requires exactly 11 digits (the 12th is a checksum).
  • Code 39 supports uppercase letters, numbers, and specific symbols, with a maximum length of about 43 characters.
  • Code 128 supports most ASCII characters but should be kept concise for readability.

Are barcodes secure?

Barcodes store data in a machine-readable format and are generated entirely in your browser, so your data stays secure. However, avoid encoding sensitive information, as barcodes can be scanned by anyone.

How do I scan a barcode?

Use a barcode scanner or a smartphone app (e.g., Barcode Scanner, Google Lens). Point the scanner or camera at the barcode to read the encoded data.
