✕Common Mistakes
Prüfen die Seriennummer des Produkts.
The infinitive cannot be used as a command; you need the imperative form.
Prüf der Seriennummer des Produkts.
‘Seriennummer’ is feminine, so the accusative article must be ‘die’, not ‘der’. ‘Der’ is masculine nominative/genitive.
Prüf die Seriennummer des Produkt.
In the genitive, neuter nouns add an -s (Produkts). Leaving it out is a common error.

Cultural Tip
In German business communication the bare imperative can sound abrupt. Adding ‘Bitte’ (Bitte prüf …) softens the request. Also, ‘Prüf’ is typical in spoken, informal contexts; in emails or manuals you’ll usually see ‘Prüfe’ or ‘Überprüfen Sie’.
