How it's used
This is a highly formal and polite way to inquire about someone's surname in a professional or service setting. It functions as a set phrase and is rarely used in casual peer-to-peer interactions where it might sound overly stiff or distant. When answering, one should never use 貴姓 to refer to oneself, as the 貴 implies respect for the other person.
Examples
Excuse me, may I ask your surname?

May I ask your surname
Common mistake
Learners often mistakenly use this when introducing themselves, but it is strictly for asking others. If you want to state your own surname, simply use 我姓 followed by your surname.
