I know half a dozen. All from the 80s and 90s, and only two which actually exist today.

Other than that I know mine and my wife’s.

Oddly enough I knew a company which had a phone number which was two digits transposed from my home number - 818614. My number until about 1993 was 818641. Didn’t realise the company was still going until a couple of weeks ago when a lorry pulled up outside my window with the name and phone number on.

The other number I remember is my school number for some reason, I can’t think of ever have rung it. It’s still the same number today, 30 years later.
