Frequently Asked Questions

Is this a QR code generator?
No. This tool creates 1D Code 128 barcodes. Use the QR Code Generator for 2D QR codes.
Can I generate EAN-13 or UPC here?
Use the EAN-13 / UPC preset landings or GTIN Check Digit Calculator for math. Dedicated EAN/UPC symbology bars are next — today those presets encode digits as Code 128 with honest FAQs.
Can I make official Meesho packaging barcodes?
No. Meesho BP-TP packet codes must come from Meesho-recommended vendors.
How do I print many labels on one page?
Use the Barcode Label Sheet tool for A4 PDF tiling (e.g. 36× 40×30 mm).
