Translation:What is your number?
wondering what the context for this would be...
at first i thought asking around as part of a queue, where i'd also be likely to say, 'what number are you?' or 'what number do you have?'
but then, is this perhaps asking what number child you are in your family?
or is about asking for someone's phone number? or house number?
or would this same phrase in indonesian work for all these contexts?
