How to Ask for and Say a Phone Number
Phone numbers demand accurate listening more than complex grammar. Ask for a number, group its digits at a comfortable pace, and confirm what you heard.
Learning objective
Exchange a phone number slowly and confirm the digits you hear.
A phone-number exchange has three jobs: ask, deliver the digits, and confirm. Ask one person informally ¿Cuál es tu número de teléfono?, meaning What is your phone number? Cuál is the accented question word which or what in this choice-seeking frame. Número means number, and teléfono means telephone.
For respectful singular address, use ¿Cuál es su número de teléfono? Su replaces informal tu here. Address choices vary with region, relationship, age, and setting, so follow local usage rather than assuming one form is always more caring. A person may also choose not to share contact details.
Say the number in short groups at a comfortable pace: Mi número es cero cuatro, uno dos tres, cuatro cinco seis. Mi número es means My number is. Phone numbers, country codes, and grouping customs differ across countries; giving individual digits is a reliable repair strategy when larger groups cause confusion.
Confirm what you heard by repeating the uncertain part: ¿Es uno dos tres? means Is it one two three? You can add Más despacio, por favor, meaning More slowly, please. Accuracy matters more than speed. In a real exchange, never invent or publish another person's private number for practice.
Examples
¿Cuál es tu número de teléfono?
What is your phone number?
Tu addresses one person informally and has no accent as the word your.
¿Cuál es su número de teléfono?
What is your phone number?
Su can accompany respectful singular address in this context.
Mi número es cero cuatro, uno dos tres.
My number is zero four, one two three.
Short digit groups support accurate listening.
¿Es uno dos tres?
Is it one two three?
Repeating a group checks what you heard.
Common mistake
- Instead of
- Mi número son cero cuatro...
- Try
- Mi número es cero cuatro...
The grammatical subject is the singular noun número, so use the singular form es even though many digits follow. Those digits identify the one number; they do not make the subject plural. Keep mi número es as a complete delivery frame.
Practice
Try it yourself
Use the fictional number 04 128 730 for a privacy-safe role-play. Partner A asks informally, Partner B gives the digits in three groups, and Partner A deliberately checks the middle group before thanking them.
