Barcode Generator FAQs
What's the main difference between UPC-A and EAN-13 barcodes?
UPC-A is a 12-digit barcode predominantly used in the United States and Canada. EAN-13 is a 13-digit barcode widely adopted globally. Our generator automatically handles the strict digit rules and check digit math for both formats.
How does the check digit work?
The check digit is the final number in UPC-A and EAN-13 barcodes, calculated to prevent scanning errors. When you use our tool, simply input your 11 (UPC) or 12 (EAN) base digits, and we auto-calculate the final check digit for you instantly.
Can I generate QR Codes in bulk?
Yes! Simply select "QR Code" from the Symbology dropdown, then click the "Excel" tab. Upload a spreadsheet of URLs or text, and the system will instantly build hundreds of high-res QR codes for you to download as a ZIP or PDF.
