Frequently Asked Questions

How do I generate barcodes in bulk to print?

Use the 'Bulk' tab, paste a list with one code per line (you can paste straight from an Excel column), choose a size, and download an A4 PDF sheet with all of them, ready to print and cut. Rows with errors are highlighted so you can fix them before generating.

Why is the barcode not generating?

Each standard has its own rules. EAN-13 requires numbers and a specific length, UPC also has a fixed digit count, while CODE128 accepts more variations. Change the format or adjust the value entered.

Does the bulk sheet fit adhesive label paper?

The sheet is an A4 grid meant for printing on plain paper and cutting by hand. It is not aligned to adhesive label templates from specific manufacturers, so avoid printing it directly onto that kind of paper.
