A quick guide

Use the number with context

The answer is only useful when you know what it includes and what it leaves out.

How to use it

  1. Enter sender and recipient addresses.
  2. Add the order reference, parcel count and optional Code 128 barcode.
  3. Print a test label and verify the carrier’s requirements.

Formula

Label = sender + recipient + parcel metadata + optional barcode value

The output is a prepared address label, not a shipment booking.

Make it concrete
