Free Barcode Generator for SKU, EAN & UPC Codes

Turn your SKU, EAN-13, UPC, or any alphanumeric code into a printable barcode — one at a time, or in bulk from a pasted list.

Paste from Excel/Sheets — each line becomes one barcode.

0 barcodes generated

This renders a barcode image from a code you provide — it does not create or register official marketplace identifiers like Amazon FNSKU or Flipkart FSN, which are assigned inside your seller dashboard.
How to Use

Step by step

1

Choose Single or Bulk

Single generates one barcode at a time; Bulk accepts a pasted list, one code per line.

2

Enter your code(s)

Type or paste your SKU, EAN, UPC, or any alphanumeric code you already have.

3

Select the format

CODE128 works for any text/SKU. EAN-13 and UPC-A are strict numeric retail standards.

4

Generate and download

Download as PNG individually, or as a ZIP for bulk batches.

Rules & Guidance

What to know before you use the output

Format requirements: EAN-13 requires exactly 13 digits, UPC-A requires exactly 12. CODE128 accepts any alphanumeric text, making it the safest choice for internal SKUs that don't follow a strict retail numbering standard.

This tool renders a barcode image from a code you already have — it does not create or register official marketplace identifiers like Amazon FNSKU or Flipkart FSN, which are assigned inside your seller dashboard.

Troubleshooting

Common questions when the output looks off

? "Invalid for format" error
Your code doesn't match the digit requirement for the selected format — 13 digits for EAN-13, 12 for UPC-A. Switch to CODE128 if your code doesn't fit a strict numeric standard.
? Barcode won't scan at checkout or in the warehouse
Print it larger. Very small barcodes lose scannability, especially on lower-resolution printers or thermal label printers.
? Can I use this for my Amazon FNSKU or Flipkart FSN?
Yes — paste the exact FNSKU or FSN text your marketplace dashboard already assigned you, and generate it as CODE128. This tool prints the barcode image; it doesn't create the identifier itself.

This tool solves one piece. SKUforge handles the rest.
