Listen to this Voki conversation to learn how to ask for a phone number.
¿Cuál es tu número de teléfono? What's your phone number? (Literal translation - Which is your number of telephone?).
Grammar Note #2: The formal way to ask this question, if you are talking to an "usted," is ¿Cuál es su número de teléfono? Remember the pronoun "su" is the formal "your," while "tu" without the accent is the familiar "your."
Mi número es (416) 491-5050. My number is (416) 491-5050.
Other ways to ask for someone's phone number:
¿Cuál es tu celular?
¿Me das tu número de celular?
¿Me das tu número de móvil?
Me das - Can you give me.
Wording Note: In Spain, people will use móvil for mobile phone instead of celular - cell phone, which is more commonly used in Latin America.
