Telephone number: 0477140478

These days, most of us have telephones that display the number that’s calling before we answer. This “feature” actually goes right back to the 1960s, and it’s known in North American English as Caller ID, although it doesn’t actually identify the caller, just the caller’s number.

If you haven’t been warned recently that your car warranty has expired, that something has gone badly wrong with your Social Security account or that you are in big trouble with the Internal Revenue Service, then you must not have a phone.
