Generating barcodes one at a time is fine for a single label. For a product catalog, an inventory count or a shipment of SKUs, you need them in bulk — and you need them validated so a scanner does not choke on a bad check digit.
Generate barcodes in bulk in four steps
- Pick one format for the batch — Code 128, EAN-13, EAN-8, UPC-A or Code 39.
- Paste your values, one per line. Each line becomes its own barcode.
- Generate the whole batch at once, right in your browser.
- Download a single zip with every barcode inside, plus an index manifest.
Which barcode format should I use?
- Code 128 — dense, flexible, good for internal SKUs and shipping labels (letters and numbers).
- EAN-13 / EAN-8 — retail products sold internationally; 13 or 8 digits with a check digit.
- UPC-A — retail products in North America; 12 digits.
- Code 39 — older but widely supported; common in logistics and ID.
EAN and UPC values are validated, including their check digits, so invalid entries are reported instead of silently producing an unscannable code.
Why bulk + zip beats one-at-a-time
When you generate a list, each barcode is named from its value and a index.csv manifest maps every value to its file. That means you can drop the zip straight into a label template or hand it to a print shop without renaming anything.
Is it really free?
Yes. You can generate up to 100 barcodes per batch for free, with no signup. Barcodes are created client-side in your browser — nothing is uploaded to a server. Sign in only if you want to save them to a dashboard.
