On a sign, a form or a delivery note

The whole code, #7RNFL-3F8RD. It needs nothing else: no city, no street, no network to read it back.

Said aloud, in West Java

Copied by hand, or read over a phone

#7RNFL-3F8RD*2. The character on the end catches any single mistyped symbol and any two neighbours swapped.
