Home > Guides > Handwriting a shipping address

Can I just write the address on a box instead of printing a label?

For a domestic parcel sent with stamps or counter postage, yes: a handwritten address is accepted and the parcel will move. But handwriting costs you the tracking barcode, and misread addresses route parcels to manual processing. For anything valuable, time-sensitive, or international, print a label instead. Buy a label through LetterAgent and the PDF is ready to print, so handwriting never comes up.

How do I make a handwritten address as reliable as possible?

Use a thick permanent marker, write in block capitals, and keep the address to one flat face of the box, large enough to read from a few feet away. Put the full address on the box: name, street address, city, province or state, and postal code. Add a return address in the upper corner. Cover the writing with a strip of clear packing tape to protect it from rain and scuffing, but write first and tape after, so the tape cannot smear wet ink.

The most common failure is handwriting on a reused box that still shows an old address. Carriers read whatever address they find; if yours is smaller or lighter than the old one, the parcel can go to the wrong destination. Completely cross out or cover every old marking before writing the new address.

What can't handwriting do?

Handwriting cannot buy you postage on its own. A handwritten address with no stamps and no counter receipt is just a marked box: it will not enter the mail stream. International parcels need printed customs forms, which cannot be handwritten; customs declarations are standardized documents with barcodes of their own. And anything you want to track needs a printed label with a tracking number: a hand-scrawled address gives the carrier no code to scan.

There is also a delivery-speed cost. Sorting equipment reads printed labels in a fraction of a second; handwritten addresses get flagged for manual keying, which adds handling steps and time. For a casual domestic gift this hardly matters. For a parcel you need to arrive by a date, the printed label is the safer play.
