what is the word you use to ask for someone's first name?
3 Answers
¿Cuál es tu nombre?
or
¿Cuál es tu nombre de pila?
I don't know about Spain, but if you ask ¿Cuál es su nombre? in Latin America they will tell you their first name. If you want first and last name you would ask ¿Cuál es su nombre completo?
Here's a link from the language guide: How to Say "What's your name?" in Spanish
Both are common in Spain and the Americas. The only difference here is the tú and usted forms.
