How to give this address

On a sign, a form or a delivery note

The whole code, #PX2XG-0P8W4. It needs nothing else: no city, no street, no network to read it back.

Said aloud, in Amsterdam

They give back the exact code for anywhere within 4.0 km north or south and 3.3 km east or west of Albert Cuyp Market. Further away the same five name somewhere else, which is why the whole code is what goes on a sign.
