✦Grammar Breakdown
Stellsicher,dassdieHausnummerstimmt.
Imperativ (du‑Form)
‘Stell’ is the du‑imperative of the verb ‘stellen’. For ‘ihr’ you would say ‘stellt’, and for a polite form ‘stellen Sie’.
Adverb ‘sicher’
Here ‘sicher’ functions as an adverb meaning ‘surely’ or ‘make sure’. It follows the imperative verb directly.
Subordinate clause with ‘dass’
‘dass’ introduces a dependent clause; the finite verb ‘stimmt’ moves to the end of that clause.
Noun gender & article
‘die Hausnummer’ is feminine; the definite article ‘die’ must agree in gender, number and case.
Verb ‘stimmen’ (3rd person singular)
In the subordinate clause the verb is in present indicative, third person singular, matching ‘die Hausnummer’.

✕Common Mistakes
Stelle sicher, dass die Hausnummer stimmt.
‘Stelle’ is the 1st‑person singular imperative (or polite ‘Sie’ form). For an informal ‘du’ you need ‘Stell’.
Stell sicher, das die Hausnummer stimmt.
‘das’ is the neuter demonstrative pronoun; the conjunction introducing a clause is ‘dass’. Using ‘das’ changes the meaning.
Stell sicher, dass die Hausnummer richtig ist.
While understandable, the idiomatic way to express the idea in a subordinate clause is ‘dass die Hausnummer stimmt’. ‘Richtig’ is less common in this construction.

Cultural Tip
In German addresses the street name comes first, followed by the Hausnummer (e.g., ‘Musterstraße 12’). Because many delivery services rely on the exact number, Germans are very particular about getting it right. Using the imperative ‘Stell sicher…’ is common in informal spoken German, but in formal written communication you might prefer ‘Bitte stellen Sie sicher…’.
