You can find your number on the screen/monitor when it's ready.
日本語の日常会話では、主語を省いて話すことがとても多いですが、英語は主語＋動詞＋〜で文が構成されます。日本語に主語がない時は、まず主語を見つけましょう。その場合、主語を「人」にすると意味が通じやすく、自然な英文になります。
「用意が出来ましたら、番号が画面に表示されますので、それまで少しお待ちください。」
＝「あなたは見つけることができます／あなたの番号を／モニターに／準備ができたら」
↑のように単語単位で訳すのではなく、情景を浮かべると英文にしやすくなりますよ。
I hope it helps．
