Those special 25 interleaved codes are used on parcel labels for shipment through the postal service in Germany. 

Two codes are used on a label:

  • The Leitcode is used to encode the destination area and requires 13 digits
  • The Identcode is used to encode the tracking number and requires 11 digits


To print the code with the correct layout, use 124 for the p parameter and 300 for the h parameter: <Esc>(s124p300h24642T
