About this Barcode Generator

Barcode Generator builds linear barcodes such as CODE128, EAN-13, and UPC-A for inventory labels, retail SKUs, and warehouse demos. Operations teams print shelf tags; developers mock POS flows; freelancers deliver product sheets with scannable IDs. Choose a symbology, enter a valid payload, generate, and download the barcode image. Generation runs in the browser so internal SKUs need not upload to an external label service. Respect check-digit rules for EAN/UPC—invalid lengths fail scanners—and verify with a hardware scanner when labels ship to stores, not only with phone apps. Validate company prefix ownership before printing retail EAN codes at scale. Leave quiet zones required by the symbology—do not crop them in layout apps. Archive the exact payload string with each SKU for future reprints.

How to use

  1. 1Select the barcode format (CODE128, EAN-13, or UPC-A).
  2. 2Enter a payload that matches the format’s length and digit rules.
  3. 3Generate the barcode preview.
  4. 4Download the barcode image for labels or docs.
  5. 5Verify with a scanner before production printing.

Frequently asked questions

What is CODE128 best for?
Flexible alphanumeric logistics codes. Retail shelf standards more often use EAN-13 or UPC-A.
Why does EAN-13 reject my number?
EAN-13 expects 13 digits including a valid check digit—length and checksum both matter.
Can I encode letters in UPC-A?
UPC-A is numeric. Use CODE128 when alphanumeric payloads are required.
Does print size matter?
Yes—bars need enough width and quiet space to scan reliably under store lighting.
Is this the same as a QR code?
No. Barcodes are linear 1D codes; QR codes are 2D matrices with different scanners and payloads.
