Shipping Label Maker (4x6 and A6, with Barcode)

Fill in the sender and recipient, an order or reference number, the weight and a service line, and the tool lays out a 4x6 inch or A6 label with a scannable Code 128 barcode of your reference. Print it on a thermal label printer or on paper. Important: this is not a postage label. Carriers such as national post services and courier companies require their own paid labels to carry a parcel; use this for return-address labels, packing labels, local delivery and internal tracking. Everything runs in your browser. Nothing you type or upload is sent to We.Inc or anyone else.

How it works

  1. Choose the label size: 4 x 6 inches (the common thermal label size) or A6 (105 x 148 mm).
  2. Enter the from / return address and the to address. Line breaks are kept exactly as you type them.
  3. Add an order or reference number. The tool encodes it as a Code 128 barcode (code set B, with its check character) right on the label.
  4. Add the weight, the number of parcels (for example 1 of 2), a service line such as "Local delivery" and an optional handling note.
  5. Check the live preview, then press Print label. A window sized to the label opens with the print dialog.
  6. In the print dialog, pick your label printer, set the paper to 4x6 or A6, and set scale to 100% ("actual size").

What this label is for, and what it is not

A shipping label from a carrier is proof that postage was paid, plus routing data the carrier's machines read. Only the carrier can issue that. A label you print yourself cannot replace it, no matter how it looks.

What you can do yourself is everything around it: a return-address label on every box, packing labels that match a box to an order, labels for parcels you deliver by hand or through a local courier you book directly, and barcode labels for tracking stock and orders inside your own business.

Printing a clean barcode

Barcodes fail most often because the printer scaled them. Always print at 100%, with no "fit to page". On thermal printers, set the media size in the printer settings to match the label so the driver does not shrink it.

Leave the white margins around the barcode alone. Scanners need that quiet zone to find where the code starts and ends.

Selling online

If you are packing orders, you may also want a shop that takes them. The brief at the bottom starts an online store website on We.Inc with your business name and shipping details. Starter is $20 a month and includes AI building and custom domains.

Tips

Frequently asked questions

Can I use this label to post a parcel?

No. This tool does not buy postage or talk to any carrier. Postal services and couriers require their own paid label with their own barcodes for a parcel to enter their network. Use this label for return addresses, packing and picking, hand deliveries, local courier runs you arrange yourself, and internal tracking.

What barcode does it make?

Code 128, code set B, which covers letters, numbers and common punctuation. The tool calculates the check character required by the standard and adds the start and stop patterns and quiet zones, so standard barcode scanners can read it.

Why won't my reference make a barcode?

Code set B only covers printable ASCII characters (space through ~). Accented letters, emoji and other symbols cannot be encoded. The tool lists any characters it cannot use so you can remove them.

What sizes are supported?

4 x 6 inches (about 102 x 152 mm), the standard size for most thermal shipping printers, and A6 (105 x 148 mm), which also prints four to a sheet of A4 if you print from a PDF.

Does it save my addresses?

No. Everything stays in this browser tab and is cleared when you close it.
