sotaさん
ご質問どうもありがとうございます。
様々な表現があると思いますが、いくつか自然な表現を紹介します。
1. Can I ask your age? 年齢聞いていいんですか？
2. May I ask how old you are? おいくつか、聞いていいんですか？
3. If you do not mind me asking. How old are you?
もしよければききたいのですが、おいくつですか？
P.S. もちろん、How old are you でもぜんぜん大丈夫です。とても自然で、丁寧で、よく使われている表現です、しかし、英語圏、Europeのそれぞれの国は、20年代超えは、るよう女性だったら、年齢を聞くのは丁寧でないと思われている声もある。
お好みに合わせて使い分けてみてください。
ご参考にしていただければ幸いです。

You can also say, "I do not mean to be disrespectful but..." and ask their age.
It may not be polite to ask this question as it is personal and some people are sensitive about this topic. In some situations such questioning may be deemed 'ageist'.
If you want to ask how old someone is, you may ask straightforwardly and say: How old are you?

It always important to be polite when asking such personal questions.
