Frequently Asked Questions
What is the difference between Code 128, EAN-13, and UPC-A barcodes?
Code 128 is a compact alphanumeric barcode used for internal SKUs, asset tracking, and shipping labels. UPC-A (12 digits) is standard for retail point-of-sale products in the US and Canada, while EAN-13 (13 digits) is used for retail products worldwide and on Amazon.
Can I generate bulk barcodes and print them on a label sheet?
Yes! Switch to Bulk Mode, paste your list of codes (one per line), and click Printable PDF Sheet or Print Sheet to output a clean grid of barcode labels on A4 or US Letter paper, or download all images as a ZIP.
Should I download PNG or SVG for my product packaging?
Choose SVG for professional packaging design (Illustrator, InDesign, Canva, CorelDRAW) because vector graphics scale to any print resolution without blurring. Choose PNG for Word documents, Excel sheets, and thermal label software.
Does the tool calculate the EAN-13 and UPC-A check digit automatically?
Yes. Enter 12 digits for EAN-13 or 11 digits for UPC-A and our encoder automatically computes and appends the modulo-10 check digit.
