telephone number
A unique sequence of digits assigned to a telephone or mobile connection and dialed in order to establish a connection.
Ich habe dich gestern versucht anzurufen, aber die Telefonnummer war nicht mehr gültig.
I tried to call you yesterday, but the telephone number was no longer valid.
The word is made up of 'Telefon' (telephone) and 'Nummer' (number). So it is literally the number of a telephone. The 'n' in the middle is a linking n that connects the two parts of the word.
Notier dir bitte meine neue Telefonnummer.
Please write down my new telephone number.
Common verbs used with 'Telefonnummer' are 'geben' (to give), 'bekommen' (to get), 'wählen' (to dial), 'haben' (to have), and 'notieren' (to write down). You can also say 'unter einer Telefonnummer anrufen' (to call at a telephone number).
Ich habe die falsche Telefonnummer gewählt und eine fremde Person war am Apparat.
I dialed the wrong telephone number, and a stranger was on the line.
To ask someone for their number, you can say: 'Wie ist deine/Ihre Telefonnummer?' (What is your telephone number?) or more politely: 'Könnte ich bitte deine/Ihre Telefonnummer haben?' (Could I please have your telephone number?).
Entschuldigung, wie ist Ihre Telefonnummer? Ich würde Sie gerne zurückrufen.
Excuse me, what is your telephone number? I would like to call you back.
number
'die Nummer' and 'die Telefonnummer' can both mean a sequence of digits. But 'die Nummer' is more general: it can be a telephone number, a house number, a customer number, or another identifying number. 'die Telefonnummer' is more specific and only means the number used to call someone. The words can be confused because in everyday speech people often simply say 'Nummer' when they actually mean a telephone number. If the context is not clear, 'Telefonnummer' is more precise.
Kannst du mir bitte deine Telefonnummer geben, damit ich dich morgen anrufen kann?
Could you please give me your telephone number so I can call you tomorrow?
