How this calculator works

The mark is formatted locally in your browser. No address, phone number or personal contact fields are requested.

Using this result

The generated mark is a printable handling reference, not a carrier label or transport document.

Next step: Check every non-personal reference before printing and add the official carrier label separately.

Worked example

Use a short consignee or project mark, purchase-order reference, carton sequence and destination code that match your commercial documents.

How to measure

  1. Use a high-contrast printer setting.
  2. Confirm the mark matches the packing list.
  3. Place labels on two visible sides when required.

Common mistakes

Planning note: This result is an estimate, not a carrier quote. Equipment, services, limits and rounding rules can vary. Confirm operational decisions with the relevant provider.
