If someone is contactable, you can write to them or telephone them — a letter, a call, or a message can get through. Offices like this word: 'Please stay contactable during the trip.' News uses it when a missing person, a parent, or a company cannot be reached. Though actually, in the kitchen nobody says 'Are you contactable?' They say 'Can I call you?' or 'Are you around?' Contactable lives in work English, school notices, and forms. It is about the line being open, not about being friendly, and not about having 'contacts' (people you know). The -able here is the quiet kind: it means 'can be contacted,' the way breakable means 'can be broken.' Some students hear it as 'good at writing to people'; that would be a different idea. You can be contactable and still not want to talk — the word only says a letter or a call can find you.
