example

Usage tips
Compound word
The word is made up of 'kennen' (to know) and 'Zeichen' (sign). A 'Kennzeichen' is therefore literally a 'sign for recognizing'. This fits both the license plate on a car and a typical feature.
EXAMPLE
Anhand der Spuren im Schnee konnten sie das Tier erkennen.
They were able to recognize the animal from the tracks in the snow.
Context clue
When it has to do with cars, traffic, or the police, it almost always means the license plate. In all other contexts, especially when describing people, animals, or things, it means 'Merkmal' (feature) or 'Eigenschaft' (quality).
EXAMPLE
Der Falschparker hatte ein Hamburger Kennzeichen.
The illegally parked car had a Hamburg license plate.
Typical collocations
In connection with license plates, typical verbs are: 'sich ein Kennzeichen merken' (to remember a license plate), 'ein Kennzeichen notieren' (to note down a license plate), or 'ein Kennzeichen überprüfen' (to check a license plate).
EXAMPLE
Der Zeuge konnte sich das Kennzeichen des Unfallwagens merken.
The witness was able to remember the license plate of the car involved in the accident.
Use with genitive
In the meaning of 'Merkmal' (feature), the genitive or 'von' + dative is often used to indicate what something is a characteristic of. For example: 'das Kennzeichen des Erfolgs' (the characteristic of success) or 'ein Kennzeichen von hoher Qualität' (a characteristic of high quality).
EXAMPLE
Die Fähigkeit zur Anpassung ist ein Kennzeichen intelligenter Systeme.
The ability to adapt is a characteristic of intelligent systems.

Kennzeichen vs Zeichen
sign / symbol
'das Zeichen' and 'das Kennzeichen' can both help you recognize or understand something. 'Zeichen' is very general: it can be a marking, a symbol, or an indication. 'Kennzeichen' more often means a typical feature by which you recognize someone or something. In everyday language, 'Kennzeichen' is also often the license plate of a car. The words can be confused because both can indicate something. If something simply carries a meaning or points to something, 'Zeichen' fits. If it is about recognizing or identifying something, 'Kennzeichen' sounds more precise.
