FNSKU/FBA Barcode Label Generator

Amazon FBA and Vendor Central sellers must stick a barcode label on every unit before dispatch, but most sellers don't have label-design software like BarTender. Fill in your SKUs below, pick your label size, and get a print-ready PDF of barcode stickers - built entirely on your device.

  1. 1
    Fill in your SKUs

    Add a row per SKU with its condition, product title, ASIN/FNSKU and how many stickers you need - or download the CSV template, fill it in Excel, and upload it back.

  2. 2
    Pick your paper or label size

    50x25mm and 100x25mm label rolls, a 4x6in shipping-label sheet, or plain A4 - the layout and sticker count per page adjust automatically.

  3. 3
    Click Generate

    A correctly-paginated PDF is built entirely on your device, with one barcode sticker per copy of each SKU.

What this tool does NOT do

Frequently asked questions

Is this tool free?

Yes, completely free, with no signup and no usage limit. There is no paid tier of this specific tool.

Does this tool upload my SKU data anywhere?

No. Everything - your table data, an uploaded template, and the generated PDF - is built and processed entirely inside your browser, in a background Web Worker. Nothing is ever sent to Servicxy or anyone else.

What is the difference between an FNSKU and an ASIN barcode?

FNSKU (Fulfillment Network Stock Keeping Unit) is the barcode Amazon requires on FBA inventory so it can tell your unit apart from another seller's identical stock in its warehouses. ASIN is Amazon's own catalog identifier - Vendor Central sellers shipping brand-new, retail-ready units typically label with the ASIN barcode instead. Either value works in the ASIN/FNSKU column - the tool just encodes whatever you put there.

What paper or label sizes are supported?

Four: a 50 x 25mm label roll (one sticker per label), a 100 x 25mm label roll (two stickers per label), a standard 4 x 6in shipping-label sheet (10 stickers per sheet), and plain A4 (48 stickers per sheet).

What happens if a product title is too long?

It wraps to a second line, and if it still doesn't fit, the second line is cut short with an ellipsis (...) - so the barcode, the ASIN/FNSKU text, and the condition/title line never overlap or run off the sticker, no matter how long the title is.

Can I upload a spreadsheet instead of typing every row?

Yes. Download the CSV template, fill it in Excel or Google Sheets (or export as .xlsx directly), and upload it - it fills the table for you. You can still add, edit or delete rows by hand afterward.

Is the barcode actually scannable?

Yes. It is a real Code128 barcode encoding the exact ASIN/FNSKU value you entered - not a picture, a freshly generated, correctly-encoded symbol.

Does this work on mobile?

Yes, though filling in a table of many SKUs is usually easier from a desktop or by uploading a spreadsheet template.
