Questions

How many barcodes can I make at once?

Up to 1,000 per run. Make several runs for more.

Can I number EAN or UPC barcodes?

Only with a GS1 company prefix your company owns. Shops reject made-up product numbers, so the tool asks you to confirm first.

What is in the CSV file?

One row per code with its number in the run and the exact value in the barcode, including any check digit. It opens in Excel, Google Sheets and label software.

Can I add letters before or after the numbers?

Yes. Use the prefix and suffix, for example BIN-0001-A. Letters need a format that accepts them, such as Code 128; formats like ITF and EAN-13 hold digits only.

Can I print the numbered codes on labels?

Yes. Select Make labels to send the whole run to the Label Maker, then choose a label size, add text such as a lot number, and download a print-ready PDF.

Is anything I type uploaded?

No. Codes are made in your browser. Nothing you enter reaches our server.
