What is your number in Spanish is a phrase that appears frequently when you need to exchange contact information, whether you’re meeting a new friend, arranging a business meeting, or simply confirming a phone detail while traveling. Understanding how to ask and answer this question correctly not only helps you communicate effectively but also shows respect for the linguistic nuances of Spanish‑speaking cultures. In this guide, we’ll break down the exact wording, explore formal and informal alternatives, highlight regional variations, and give you practical examples so you can use the phrase confidently in any situation Small thing, real impact..
Direct Translation: The Core Phrase
The most literal translation of “What is your number?” in Spanish is:
¿Cuál es tu número?
- ¿Cuál es? – “What is?” (used when asking for a specific item from a known set)
- tu – informal singular “your”
- número – “number”
If you need to be polite or address someone you don’t know well, replace tu with the formal su:
¿Cuál es su número?
Both versions are grammatically correct and widely understood across the Spanish‑speaking world. The choice between tu and su hinges on the level of familiarity and the social context, a point we’ll expand on in the next section Took long enough..
Formal vs. Informal: Choosing the Right Pronoun
Spanish distinguishes between informal (tú) and formal (usted) address. This distinction affects not only verbs but also possessive pronouns.
| Context | Pronoun | Phrase | When to Use |
|---|---|---|---|
| Informal (friends, peers, same age) | tu | ¿Cuál es tu número? | Business meetings, official appointments, speaking to someone older or in authority |
| Plural informal (Spain) | vuestro | ¿Cuál es vuestro número? | Casual settings, among classmates, teammates, or friends |
| Formal (strangers, elders, professionals) | su | ¿Cuál es su número? | Rarely used; mostly heard in certain regions of Spain when addressing a group familiarly |
| Plural formal (Latin America & Spain) | su (same as singular) | ¿Cuál es su número? |
Note: In many Latin American countries, the formal usted form is used even in situations that might feel informal elsewhere, so erring on the side of politeness is often safe.
Regional Variations and Alternative Expressions
While ¿Cuál es tu/su número? is the standard, Spanish speakers sometimes use synonyms or colloquial shortcuts depending on the region Not complicated — just consistent..
1. Using “teléfono” Explicitly
In contexts where you want to make it clear you’re asking for a phone number, you can add teléfono:
- ¿Cuál es tu número de teléfono?
- ¿Cuál es su número de teléfono?
Adding teléfono removes any ambiguity, especially useful when talking to someone who might think you’re asking for a lucky number, jersey number, or ID number.
2. Colloquial Shortcuts
In everyday speech, especially among younger speakers, you may hear:
- ¿Cuál es tu número? → often shortened to ¿Tu número? in fast conversation (common in Mexico, Colombia, and Chile).
- ¿Me das tu número? – “Can you give me your number?” (a request rather than a question).
- ¿Pass me tu número? – Spanglish heard in border areas or among bilingual youth.
3. Regional Preferences
- Argentina & Uruguay: The voseo form replaces tú with vos, leading to ¿Cuál es tu número? still being understood, but you might also hear ¿Cuál es tu número? with vos verb conjugations in other contexts (e.g., ¿Cómo estás? → ¿Cómo andás?). For the number question, the pronoun stays tu because possessive forms don’t change with voseo.
- Caribbean (Puerto Rico, Dominican Republic): Speakers often drop the s in plural forms, but the singular question remains unchanged.
- Spain: In some northern areas, you might hear ¿Cuál es tu móvil? using móvil (mobile phone) instead of número.
Understanding these nuances helps you sound natural and avoid sounding overly textbook‑like.
Common Situations Where You’ll Need the Phrase
Knowing when to ask for a number is just as important as how to ask it. Below are typical scenarios and the appropriate level of formality.

- Mi número es… – “My number is…”
- Followed by the digits, often paused for clarity.
Example (Mexico)
Mi número es cinco cinco cinco, uno dos tres cuatro, cinco seis siete ocho.
(555‑1234‑5678)
Example (Spain)
Mi número es seis, uno dos tres, cuatro cinco seis, siete ocho nueve.

- Confirm – After giving your number, you can ask ¿Lo entendiste? (“Did you get it?”) to ensure accuracy.
