This was a very fun bit of exploration with @timohetzel @smrqdt & @datawrangler2

Now I know more about how DHL routes packages than any normal person would ever need to know

And if my 📦 doesn't arrive tomorrow... the person at the 📞 centre isn't going to know what hit them!

To cut a long story short: every part of Germany has a Postleitzahl (like a ZIP code), but these cover pretty large areas

Deutsche Post and DHL then have two other numbers at the start of "Leitcode" to route a package - the "Straßenkennzahl" that is the number of the street...

and then the number of the house.

So - for example - 85570.125.008 takes you to:
Schweigerweg 8
85570 Markt Schwaben

Or
32312.302.012 is:
Wittekindstr. 12
32312 Lübbecke

You can basically turn any German address into an 11 figure number.

The problem is finding out what the "Straßenkennzahl" is - as this is not public, but the logic is known - these were allocated alphabetically back some time between 1989 and 1994. And then newly built streets, or streets newly allocated to a Postleitzahl come at the end.

So if your Deutsche Post or DHL packages are *not* arriving, check your Leitcode is correct...

Now fingers crossed some parts of a ceiling lamp arrive tomorrow - so I can get the hall lighting fixed in my new flat!
