How to give this address

On a sign, a form or a delivery note

The whole code, #J213P-6MMT3. It needs nothing else: no city, no street, no network to read it back.

Copied by hand, or read over a phone

#J213P-6MMT3*8. The character on the end catches any single mistyped symbol and any two neighbours swapped.
