How to give this address

On a sign, a form or a delivery note

The whole code, #G6TWJ-X10J9. It needs nothing else: no city, no street, no network to read it back.

Copied by hand, or read over a phone

#G6TWJ-X10J9*7. The character on the end catches any single mistyped symbol and any two neighbours swapped.
