For a shipment to be processed automatically and delivered without issues, the address must be routable (leitcodierbar) according to DHL and Deutsche Post standards.
What does "leitcodierbar" mean?
DHL and Deutsche Post use automated sorting systems that assign every parcel a numeric routing code (Leitcode) based on the delivery address. For this to work, the address must:
Contain a valid street name and house number
Have a correct postal code (PLZ) that matches the city
Be free of typos or format errors
If an address cannot be routed automatically, the parcel may be delayed, returned, or require manual intervention – all of which cost you time and money.
