What Is Identcode?
The Identcode is Deutsche Post's internal identifier for letter-center-to-letter-center and parcel flows: 12 digits decomposing into an ID-center code, customer code, mailing-date indicator, and a Mod 10 check digit. It is printed as an Interleaved 2 of 5 symbol with a leading start delimiter, historically accompanied by the Leitcode for address-level routing.
The structure belongs to Deutsche Post's POSTA/automation chain rather than to any international standard; the numbers are assigned by DHL/Deutsche Post systems, not chosen freely. For shippers, the practical path is obtaining the code from the postal system that will carry the item. The carrier symbology is plain ITF, so any ITF-capable scanner reads it.
Common Applications
- Deutsche Post internal mail and parcel routing
