How do you add an expiration date to an FNSKU label?
Enter the Best By date in Amazon's field on the Send to Amazon page like you normally do, then click the "Print Label with Date" button FNSKU Label adds next to "Print SKU labels". The extension reads the date off the page and prints it onto a compliant FNSKU label automatically — no retyping, no PDFs. See the full walkthrough →
Which label printers does FNSKU Label work with?
Any thermal label printer — it prints through your browser. There are built-in size presets for DYMO (LabelWriter 450, 550, 4XL and more), Rollo, and Zebra desktop printers, plus custom label sizes for anything else.
Does it work outside the United States?
Yes. FNSKU Label works on Amazon Seller Central across every marketplace — North America, Europe, and beyond — not just amazon.com, amazon.co.uk, and amazon.ca.
Is my product and shipment data private?
Completely. Your FNSKU, product title, quantity, and dates are read and printed entirely in your browser and never leave your device. The only thing sent off-device is your license key and an anonymous device ID — used solely to validate your subscription. Read the privacy policy →
How many devices can I use one license on?
Up to 3 devices on a single license — for example an office computer, a warehouse station, and a laptop. Chrome and Edge installs each count as one device.
What if FNSKU isn't showing on the Send to Amazon page?
Open Display preferences on the Send to Amazon page and turn on FNSKU (and Condition). FNSKU Label reads what's visible on the row, so if FNSKU isn't shown the print button won't appear — and the extension shows a banner reminding you to enable it.
Can I print labels for items without an expiration date?
Yes. Items without a Best By date print a clean standard FNSKU label with the barcode, FNSKU, and product title — the date line is simply left off. The button reads "Print Label" instead of "Print Label with Date" on those rows.
Can I make a label smaller for tiny products?
Yes — that's the Scale feature. Type a percentage in the per-row Scale % box and the label shrinks to fit, perfectly centered, so it sits on small items without overhanging and the barcode still scans. You can also set a default scale for all labels in Settings. More on scaling →
How much does it cost, and can I cancel?
FNSKU Label is $99/year — unlimited labels, 3 devices, every marketplace, free updates, and email support. Cancel anytime, and there's a 14-day money-back guarantee. See pricing →
Do I need my Amazon password or API access?
No. FNSKU Label never asks for your Amazon credentials and uses no API. It simply reads the information already visible on the Send to Amazon page while you're logged in, the same way you'd read it yourself.
