phone number
📞🔢 전화 (電話 electric talk = phone) + 번호 (番號 number) = phone number
Four hanja: 電 electric + 話 speech = 전화, telephone; 番 turn/order + 號 mark = 번호, number. Same characters as Japanese 電話番号 (denwa bangō). 번호 recurs in 비밀번호 (password) and 번호판 (licence plate), so learning it here pays off twice.
