Frequently Asked Questions

What is the difference between Code 128, EAN-13, and UPC-A?

Code 128: A highly versatile, high-density format that supports full ASCII characters (alphanumeric, symbols, and case-sensitive data). Used widely in shipping, packaging, and asset tracking.

EAN-13: A standard barcode layout used internationally (outside North America) on retail consumer products. It expects 12 data digits + 1 checksum digit (13 digits total).

UPC-A: The standard retail product barcode layout used in North America. It expects 11 data digits + 1 checksum digit (12 digits total).

How does the automatic barcode validation system help me?
Our system checks your inputs dynamically. If you format an EAN-13 or UPC-A code with missing check digits (e.g. 12 digits for EAN-13), it calculates the checksum digit and appends it automatically. If invalid character configurations are introduced, the generator displays structured warning messages.
How can I print bulk barcode stickers using A4 sticker sheets?
Select the Bulk A4 Sheets mode, choose a standard preset layout (such as 3x8 or 4x10 label layout) or create your own custom layout, and enter your codes. Hit 'Save Print-Ready PDF' to compile your sheet layout perfectly. You can feed this PDF directly into an office printer containing sticker papers.
Are my barcode configurations private?
Yes, 100%. The tool relies entirely on local Javascript modules (JsBarcode, html2canvas, and jsPDF) to compute and render files. None of your data, product titles, or price information is sent to a server.
