Common ways of asking for someones phone number


I saw somewhere today that [電話]{でんわ}[番号]{ばんごう}は何番ですか is used to ask for
someone's phone number. It seemed strange to me since I usually hear it as
[電話]{でんわ}[番号]{ばんごう}何ですか, and also because the literal translation "What are
the **number** s, in your phone **number**?" sounds like it has some
redundancy in it.

So my question is, which is more common?




あなたの電話番号は何番ですか? is a common way of asking someone’s telephone number. We don’t
have distinction of singular and plural form as you know. So its direct
translation would be “What (number) is your telephone number? We don’t think
it’s redundant.

I think 貴方の電話, 何番ですか？is passable. But “貴方の電話番号は何ですか？” sounds weird and odd to
me. You can also say “(あなたの)電話番号を教えて頂けますか？” in polite manner.




I think both of your sentences are occasionally used but the most common way
of saying it is "電話番号を教えてください".
